This spreadsheet contains data for two future UK scenarios: a "baseline" (i.e. no climate action after 2008 the start of the carbon budget system) and the "central" scenario underpinning the CCC's advice on the fifth carbon budget (the limit to domestic emissions during the period 2028-32).<br/>The central scenario is an assessment of the technologies and behaviours that would prepare for the 2050 target cost-effectively while meeting the other criteria in the Climate Change Act (2008) based on central views of technology costs fuel prices carbon prices and feasibility. It is not prescriptive nor is it the only scenario considered for meeting the carbon budgets. For further details on our scenarios and how they were generated see the CCC report Sectoral scenarios for the Fifth Carbon Budget. The scenario was constructed for the CCC's November 2015 report and has not been further updated for example to reflect outturn data for 2015 or changes to Government policy.

Hydrogen is recognized as a promising and attractive energy carrier to decarbonize the sectors responsible for global warming such as electricity production industry and transportation. However although hydrogen releases only water as a result of its reaction with oxygen through a fuel cell the hydrogen production pathway is currently a challenging issue since hydrogen is produced mainly from thermochemical processes (natural gas reforming coal gasification). On the other hand hydrogen production through water electrolysis has attracted a lot of attention as a means to reduce greenhouse gas emissions by using low-carbon sources such as renewable energy (solar wind hydro) and nuclear energy. In this context by providing an environmentally-friendly fuel instead of the currently-used fuels (unleaded petrol gasoline kerosene) hydrogen can be used in various applications such as transportation (aircraft boat vehicle and train) energy storage industry medicine and power-to-gas. This article aims to provide an overview of the main hydrogen applications (including present and future) while examining funding and barriers to building a prosperous future for the nation by addressing all the critical challenges met in all energy sectors.

This report sets out our advice on the fifth carbon budget covering the period 2028-2032 as required under Section 4 of the Climate Change Act; the Government will propose draft legislation for the fifth budget in summer 2016.

This report for the CCC by Madano and Element Energy assesses the public acceptability of two alternative low-carbon technologies for heating the home: hydrogen heating and heat pumps.

These technologies could potentially replace natural gas in many UK households as part of the government’s efforts to decrease carbon emissions in the UK.

The report’s key findings are:

• carbon emissions reduction is viewed as an important issue but there is limited awareness of the need to decarbonise household heating or the implications of switching over to low-carbon heating technologies
• acceptability of both heating technologies is limited by a lack of perceived tangible consumer benefit which has the potential to drive scepticism towards the switch over more generally
• heating technology preferences are not fixed at this stage although heat pumps appear to be the favoured option in this research studythree overarching factors were identified as influencing preferences for heating technologies.

These factors manifested differently for different people meaning that the same factor could lead one person to prefer heat pumps and another to prefer hydrogen depending on their overall heating preferences and understanding of the two technologies. The factors are:

• perceptions of the negative installation burden
• familiarity with the lived experience of using the technologies for heating
• perceptions of how well the technologies would meet modern heating needs both hydrogen heating and heat pumps face significant challenges to secure public acceptability

The CCC has established a variety of viable scenarios in which UK decarbonisation targets can be met. Each has consequences for the way in which the UK’s gas network infrastructure is utilised. This report considers the implications of decarbonisation for the future regulation of the gas grid.<br/>The CCC’s 5th Carbon Budget envisaged different scenarios that would enable the UK to meet its emissions targets for 2050. These scenarios represent holistic analyses based on internally consistent combinations of different technologies which could deliver carbon reductions across different sectors of the economy.<br/>The CCC’s scenarios incorporate projections of the demand for natural gas to 2050. The scenarios imply that the volume of throughput on the gas networks1 and the nature and location of network usage is likely to change significantly to meet emissions targets. They are also characterised by significant uncertainty.<br/>Under some decarbonisation scenarios gas networks could be re-purposed to supply hydrogen instead of natural gas meaning there would be ongoing need for network infrastructure.<br/>In other scenarios gas demand in buildings is largely replaced by electric alternatives meaning portions of the low pressure gas distribution networks could be decommissioned.<br/>Patchwork scenarios are also possible in which there is a mixture of these outcomes across the country.<br/>In this project the CCC wished to assess the potential implications for gas networks under these different demand scenarios; and evaluate the associated challenges for Government and regulatory policy. The challenge for BEIS and Ofgem is how to regulate in a way that keeps options open while uncertainty persists about the best solution for the UK; and at the same time how best to make policy and regulatory decisions which would serve to reduce this uncertainty. Both Government and Ofgem have policy and regulatory levers that they can use – and we identify and evaluate such levers in this report.

This is the CCC’s eighth annual report on the UK’s progress in meeting carbon budgets.

The report shows that greenhouse gas emissions have fallen rapidly in the UK power sector but that progress has stalled in other sectors such as:

• heating in buildings
• transport
• industry
• agriculture

The report also outlines the Committee’s view of key criteria for the government’s ’emissions reduction plan’ published later in 2017

In this report the Committee sets out how Northern Ireland can reduce its greenhouse gas emissions between now and 2030 in order to meet UK-wide climate change targets.

The report’s key findings are:

• Existing policies are not enough to deliver this reduction
• There are excellent opportunities to close this gap and go beyond 35%
• Meeting the cost-effective path to decarbonisation in Northern Ireland will require action across all sectors of the economy and a more joined-up approach

Overall Northern Ireland’s fair contribution to the UK’s fifth carbon budget requires emissions reductions of at least 35% against 1990 levels by 2030.

The Scottish Act sets a long-term target to reduce emissions of greenhouse gases (GHGs) by at least 80% in 2050 relative to 1990 with an interim target to reduce emissions by 42% in 2020. Secondary legislation passed in October 2010 and October 2011 also set a series of annual emission reduction targets for 2010 to 2022 and 2023 to 2027 respectively. We advised the Scottish Government on annual targets for the period 2028 to 2032 in March 2016 and July 2016.<br/>The report reveals that Scotland’s annual emissions reduction target for 2014 was met with gross Scottish greenhouse gas emissions including international aviation and shipping falling by 8.6% in 2014. This compares to a 7.3% fall for the UK as a whole. Since 1990 gross Scottish emissions have fallen nearly 40% compared to nearly 33% at a UK level.

This report by the Committee on Climate Change (CCC) assesses the potential role of hydrogen in the UK’s low-carbon economy.

It finds that hydrogen:

• is a credible option to help decarbonise the UK energy system but its role depends on early Government commitment and improved support to develop the UK’s industrial capability
• can make an important contribution to long-term decarbonisation if combined with greater energy efficiency cheap low-carbon power generation electrified transport and new ‘hybrid’ heat pump systems which have been successfully trialled in the UK
• could replace natural gas in parts of the energy system where electrification is not feasible or is prohibitively expensive for example in providing heat on colder winter days industrial heat processes and back-up power generation
• is not a ‘silver bullet’ solution; the report explores some commonly-held misconceptions highlighting the need for careful planning

The report’s key recommendations are:

• Government must commit to developing a low-carbon heat strategy within the next three years
• Significant volumes of low-carbon hydrogen should be produced in a carbon capture and storage (CCS) ‘cluster’ by 2030 to help the industry grow
• Government must support the early demonstration of the everyday uses of hydrogen in order to establish the practicality of switching from natural gas to hydrogen
• There is low awareness amongst the general public of reasons to move away from natural gas heating to low-carbon alternatives
• A strategy should be developed for low-carbon heavy goods vehicles (HGVs) which encourages a move away from fossil fuels and biofuels to zero-emission solutions by 2050

The Committee on Climate Change commissioned Ricardo Energy and Environment to carry out research to assess the infrastructure requirements and costs for the deployment of different zero emission heavy goods vehicle (HGV) technology options. The infrastructure considered includes hydrogen refuelling stations ultra-rapid charge points at strategic locations electric overhead recharging infrastructure on the roads and hybrid solutions combining these options.

The research concluded:

It is feasible to build refuelling infrastructure to support the deployment of zero emission HGVs so that they constitute the vast majority of vehicles on the roads by 2050.

Looking at infrastructure alone deploying hydrogen refuelling stations is the cheapest of the options costing a total of £1.7bn in capital expenditure in the time period from now until 2060. The strategic deployment of ultra-rapid charge points is the most expensive at £10.7bn. In all scenarios a significant number of smaller electric HGVs are deployed as these options are available and operating on the streets today. The cost of installing chargers at depots for these vehicles is included.

When the costs of the fuel as well as the infrastructure are included the costs of deploying electricity or hydrogen HGVs are cheaper compared to the continued use of diesel.

Moving to zero-carbon infrastructure for HDVs is a significant challenge and requires planning co-ordination supply chains resource and materials and a skilled workforce as well as strong government policy to enable the market to deliver.

This research considers the potential role of hydrogen in meeting the UK’s carbon budgets. It was written by consultancy E4tech.<br/>The CCC develops scenarios for the UK’s future energy system to assess routes to decarbonisation and to advise UK Government on policy options. Uncertainty to 2050 is considerable and so different scenarios are needed to assess different trajectories targets and technology combinations. Some of these scenarios assess specific technologies or fuels which have the potential to make a significant contribution to future decarbonisation.<br/>Hydrogen is one such fuel. It has been included in limited quantities in some CCC scenarios but not extensively examined in part due to perceived or anticipated higher costs than some other options. But as hydrogen technology is developed and deployed the cost projections and other performance indicators have become more favourable.

When looking out to 2050 there is huge uncertainty surrounding how gas will be consumed transported and sourced in Great Britain (GB). The extent of the climate change challenge is now widely accepted and the UK Government has introduced a legislative requirement for aggressive reductions in carbon dioxide (CO2) emissions out to 2050. In addition at European Union (EU) level a package of measures has been implemented to reduce greenhouse gas emissions improve energy efficiency and significantly increase the share of energy produced from renewable sources by 2020. These policy developments naturally raise the question of what role gas has to play in the future energy mix.



To help inform this debate the Energy Networks Association Gas Futures Group (ENA GFG) commissioned Redpoint and Trilemma to undertake a long-range scenario-based modelling study of the future utilisation of gas out to 2050 and the consequential impacts of this for gas networks. Our modelling assumptions draw heavily on the Department of Energy and Climate Change (DECC) 2050 Pathways analysis and we consider that our conclusions are fully compatible with both DECC‟s work and current EU policy objectives.

Natural gas plays a central role in the UK energy system today but it is also a significant source of greenhouse gas (GHG) emissions. The UK committed in 2008 to reduce GHG emissions by at least 80% compared to 1990 levels by 2050. In June 2019 a more ambitious target was adopted into law and the UK became the first major economy to commit to “net-zero” emissions by 2050. In this context the Energy Networks Association (ENA) commissioned Navigant to explore the role that the gas sector can play in the decarbonisation of the Great Britain (GB) energy system. In this report we demonstrate that low carbon and renewable gases can make a fundamental contribution to the decarbonisation pathway between now and 2050.

This report commissioned by the Hydrogen Council and announced in conjunction with the launch of the initiative at the World Economic Forum in January 2017 details the future potential that hydrogen is ready to provide and sets out the vision of the Council and the key actions it considers fundamental for policy makers to implement to fully unlock and empower the contribution of hydrogen to the energy transition.

In this paper we explore the role of hydrogen in the energy transition including its potential recent achievements and challenges to its deployment. We also offer recommendations to ensure that the proper conditions are developed to accelerate the deployment of hydrogen technologies with the support of policymakers the private sector and society.

Hydrogen solutions have a critical role to play in the UK not only in helping the nation meet its net-zero target but in creating the economic growth and jobs that will kickstart the green recovery.

The Government must act now to ensure that the UK capitalises on the opportunity presented by hydrogen and builds a world-leading industry.

COVID-19 has caused significant economic upheaval across the country with unemployment expected to reach up to 14.8 per cent by the end of 20201. The UK must identify those areas of the economy which have significant economic growth potential and can deliver long-term and sustainable increases in GVA and jobs. It will be important to consider regional factors and ensure that investment is targeted in those areas that have been hardest hit by the crisis.

Many major economies have identified hydrogen as a key part of both decarbonisation and economic recovery. As part of its stimulus package Germany announced a €9billion investment in green hydrogen solutions aiming to deploy 5GW by 2030. The Hydrogen Council estimates a future hydrogen and equipment market worth $2.5 trillion globally by 2050 supporting 30 million new jobs.

Hydrogen offers the UK a pathway to deep cost-effective decarbonisation while delivering economic growth and job creation. It should therefore be at the heart of the Government’s green recovery programme ensuring that the UK builds back better and greener.

• Economic impact Assessment of the Hydrogen Value Chain of the UK infographic
• Imperial College Consultants Review of the EIA.

The Energy Innovation Needs Assessment (EINA) aims to identify the key innovation needs across the UK’s energy system to inform the prioritisation of public sector investment in low-carbon innovation. Using an analytical methodology developed by the Department for Business Energy & Industrial Strategy (BEIS) the EINA takes a system level approach and values innovations in a technology in terms of the system-level benefits a technology innovation provides. This whole system modelling in line with BEIS’s EINA methodology was delivered by the Energy Systems Catapult (ESC) using the Energy System Modelling Environment (ESMETM) as the primary modelling tool.

To support the overall prioritisation of innovation activity the EINA process analyses key technologies in more detail. These technologies are grouped together into sub-themes according to the primary role they fulfil in the energy system. For key technologies within a sub-theme innovations and business opportunities are identified. The main findings at the technology level are summarised in sub-theme reports. An overview report will combine the findings from each sub-theme to provide a broad system-level perspective and prioritisation.

This EINA analysis is based on a combination of desk research by a consortium of economic and engineering consultants and stakeholder engagement. The prioritisation of innovation and business opportunities presented is informed by a workshop organised for each sub-theme assembling key stakeholders from the academic community industry and government.

This report was commissioned prior to advice being received from the CCC on meeting a net zero target and reflects priorities to meet the previous 80% target in 2050. The newly legislated net zero target is not expected to change the set of innovation priorities rather it will make them all more valuable overall. Further work is required to assess detailed implications.

Where does hydrogen fit into a global sustainable energy strategy for the 21st century as we face the enormous challenges of irreversible climate change and uncertain oil supply? This fundamental question is addressed by sketching a sustainable energy strategy that is based predominantly on renewable energy inputs and energy efficiency with hydrogen playing a crucial and substantial role. But this role is not an ex -distributed hydrogen production storage and distribution centres relying on local renewable energy sources and feedstocks would be created to avoid the need for an expensive long-distance hydrogen pipeline system. There would thus be complementary use of electricity and hydrogen as energy vectors. Importantly bulk hydrogen storage would provide the strategic energy reserve to guarantee national and global energy security in a world relying increasingly on renewable energy; and longer-term seasonal storage on electricity grids relying mainly on renewables. In the transport sector a 'horses for courses' approach is proposed in which hydrogen fuel cell vehicles would be used in road and rail vehicles requiring a range comparable to today's petrol and diesel vehicles and in coastal and international shipping while liquid hydrogen would probably have to be used in air transport. Plug-in battery electric vehicles would be reserved for shorter-trips. Energy-economic-environmental modelling is recommended as the next step to quantify the net benefits of the overall strategy outlined.

Hydrogen will play a pivotal role in achieving an affordable clean and prosperous economy. Hydrogen allows for cost-efficient bulk transport and storage of renewable energy and can decarbonise energy use in all sectors.

The European Union together with North Africa Ukraine and other neighbouring countries have a unique opportunity to realise a green hydrogen system. Europe including Ukraine has good renewable energy resources while North Africa has outstanding and abundant resources. Europe can re-use its gas infrastructure with interconnections to North-Africa and other countries to transport and store hydrogen. And Europe has a globally leading industry for clean hydrogen production especially in electrolyser manufacturing.

If the European Union in close cooperation with its neighbouring countries wants to build on these unique assets and create a world leading industry for renewable hydrogen production the time to act is now. Dedicated and integrated multi GW green hydrogen production plants will thereby unlock the vast renewable energy potential.

We the European hydrogen industry are committed to maintaining a strong and world-leading electrolyser industry and market and to producing renewable hydrogen at equal and eventually lower cost than low-carbon (blue) hydrogen. A prerequisite is that a 2x40 GW electrolyser market in the European Union and its neighbouring countries (e.g. North Africa and Ukraine) will develop as soon as possible.

A roadmap for 40 GW electrolyser capacity in the EU by 2030 shows a 6 GW captive market (hydrogen production at the demand location) and 34 GW hydrogen market (hydrogen production near the resource). A roadmap for 40 GW electrolyser capacity in North Africa and Ukraine by 2030 includes 7.5 GW hydrogen production for the domestic market and a 32.5 GW hydrogen production capacity for export.

If a 2x40 GW electrolyser market in 2030 is realised alongside the required additional renewable energy capacity renewable hydrogen will become cost competitive with fossil (grey) hydrogen. GW-scale electrolysers at wind and solar hydrogen production sites will produce renewable hydrogen cost competitively with low-carbon hydrogen production (1.5-2.0 €/kg) in 2025 and with grey hydrogen (1.0-1.5 €/kg) in 2030.

By realizing 2x40 GW electrolyser capacity producing green hydrogen about 82 million ton CO₂  emissions per year could be avoided in the EU. The total investments in electrolyser capacity will be 25-30 billion Euro creating 140000- 170000 jobs in manufacturing and maintenance of 2x40 GW electrolysers.

The industry needs the European Union and its member states to design create and facilitate a hydrogen market infrastructure and economy. Crucial is the design and realisation of new unique and long-lasting mutual co-operation mechanisms on political societal and economic levels between the EU and North Africa Ukraine and other neighbouring countries.

The unique opportunity for the EU and its neighbouring countries to develop a green hydrogen economy will contribute to economic growth the creation of jobs and a sustainable affordable and fair energy system. Building on this position Europe and its neighbours can become world market leaders for green hydrogen production technologies.

A core theme of the UK Government's new Industrial Strategy is exploiting opportunities for domestic supply chain development. This extends to a special ‘Automotive Sector Deal’ that focuses on the shift to low emissions vehicles (LEVs). Here attention is on electric vehicle and battery production and innovation. In this paper we argue that a more straightforward gain in terms of framing policy around potential economic benefits may be made through supply chain activity to support refuelling of battery/hydrogen vehicles. We set this in the context of LEV refuelling supply chains potentially replicating the strength of domestic upstream linkages observed in the UK electricity and/or gas industries. We use input-output multiplier analysis to deconstruct and assess the structure of these supply chains relative to that of more import-intensive petrol and diesel supply. A crucial multiplier result is that for every £1million of spending on electricity (or gas) 8 full-time equivalent jobs are supported throughout the UK. This compares to less than 3 in the case of petrol/diesel supply. Moreover the importance of service industries becomes apparent with 67% of indirect and induced supply chain employment to support electricity generation being located in services industries. The comparable figure for GDP is 42%.

Hydrogen has emerged as an important part of the clean energy mix needed to ensure a sustainable future. Falling costs for hydrogen produced with renewable energy combined with the urgency of cutting greenhouse-gas emissions has given clean hydrogen unprecedented political and business momentum.



This paper from the International Renewable Energy Agency (IRENA) examines the potential of hydrogen fuel for hard-to-decarbonise energy uses including energy-intensive industries trucks aviation shipping and heating applications. But the decarbonisation impact depends on how hydrogen is produced. Current and future sourcing options can be divided into grey (fossil fuel-based) blue (fossil fuel-based production with carbon capture utilisation and storage) and green (renewables-based) hydrogen. Green hydrogen produced through renewable-powered electrolysis is projected to grow rapidly in the coming years.



Among other findings:



Important synergies exist between hydrogen and renewable energy. Hydrogen can boost renewable electricity market growth and broaden the reach of renewable solutions.

• Electrolysers can add demand-side flexibility. In advanced European energy markets electrolysers are growing from megawatt to gigawatt scale.
• Blue hydrogen is not inherently carbon free. This type of production requires carbon-dioxide (CO2) monitoring verification and certification.
• Synergies may exist between green and blue hydrogen deployment given the chance for economies of scale in hydrogen use or logistics.
• A hydrogen-based energy transition will not happen overnight. Hydrogen use is likely to catch on for specific target applications. The need for new supply infrastructure could limit hydrogen use to countries adopting this strategy.
• Dedicated hydrogen pipelines have existed for decades and could be refurbished along with existing gas pipelines. The implications of replacing gas abruptly or changing mixtures gradually should be further explored.

Trade of energy-intensive commodities produced with hydrogen including “e-fuels” could spur faster uptake or renewables and bring wider economic benefits.

Initial assessment of Scotland’s opportunity to produce green hydrogen from offshore wind

Summary of Key Findings

• Scotland has an abundant offshore wind resource that has the potential to be a vital component in our net zero transition. If used to produce green hydrogen offshore wind can help abate the emissions of historically challenging sectors such as heating transport and industry.
• The production of green hydrogen from offshore wind can help overcome Scotland’s grid constraints and unlock a massive clean power generation resource creating a clean fuel for Scottish industry and households and a highly valuable commodity to supply rapidly growing UK and European markets.
• The primary export markets for Scottish green hydrogen are expected to be in Northern Europe (Germany Netherlands & Belgium). Strong competition to supply these markets is expected to come from green hydrogen produced from solar energy in Southern Europe and North Africa.
• Falling wind and electrolyser costs will enable green hydrogen production to be cost-competitive in the key transport and heat sectors by 2032. Strategic investment in hydrogen transportation and storage is essential to unlocking the economic opportunity for Scotland.
• Xodus’ analysis supports a long-term outlook of LCoH falling towards £2/kg with an estimated reference cost of £2.3 /kg in 2032 for hydrogen delivered to shore.
• Scotland has extensive port and pipeline infrastructure that can be repurposed for hydrogen export to the rest of UK and to Europe. Pipelines from the ‘90s are optimal for this purpose as they are likely to retain acceptable mechanical integrity and have a metallurgy better suited to hydrogen service. A more detailed assessment of export options should be performed to provide a firm foundation for early commercial green hydrogen projects.
• There is considerable hydrogen supply chain overlap with elements of parallel sectors most notably the oil and gas offshore wind and subsea engineering sectors. Scotland already has a mature hydrocarbon supply chain which is engaged in supporting green hydrogen. However a steady pipeline of early projects supported by a clear financeable route to market will be needed to secure this supply chain capability through to widescale commercial deployment.
• There are gaps in the Scottish supply chain in the areas of design manufacture and maintenance of hydrogen production storage and transportation systems. Support including apprenticeships will be needed to develop indigenous skills and capabilities in these areas.
• The development of green hydrogen from offshore wind has the potential to create high value jobs a significant proportion which are likely to be in remote rural/coastal communities located close to offshore wind resources. These can serve as an avenue for workers to redeploy and develop skills learned from oil and gas in line with Just Transition principles.

The next few decades are expected to be among the most transformative the energy sector has ever seen. Arup envisages a world with a much more diverse range of heating sources and with significantly lower emissions and renewable energy powering transport.<br/>As part of this the establishment of a strong hydrogen economy is a very real opportunity and is within reaching distance. Our report uses the UK as a case study example and explores the challenges and opportunities for hydrogen in the context of the whole energy system.<br/>Read about the progress already being made in using hydrogen for transport and heat. And the need to progress policy and collaboration between government the private sector and other stakeholders to shape future demand change consumer perception and create the strong supply chains needed to allow the hydrogen economy to thrive.

With the growing need for decarbonization the future gas demand will decrease and the necessity of a gas distribution network is at stake. A remaining industrial gas demand on the distribution network level could lead to industry becoming the main gas consumer supplied by the gas distribution network leading to the question: can industry keep the gas distribution network alive? To answer this research question a three-stage analysis was conducted starting from a rough estimate of average gas demand per production site and then increasing the level of detail. This paper shows that about one third of the German industry sites investigated are currently supplied by the gas distribution network. While the steel industry offers new opportunities the food and tobacco industry alone cannot sustain the gas distribution network by itself.

Through its “Reducing Carbon whilst Creating Social Value: How to get Started’ initiative Welsh Government is keen to explore whether a ‘circular economy’ (and industry) could be developed for Wales for CO2.<br/>Although most companies have targets to reduce their CO2 by 2030 Wales does not have the space to store or bury any excess with the current choice to ship or ‘move the problem’ elsewhere. Meanwhile other industry sectors in Wales are experiencing shortages of CO2 e.g. food production.<br/>Net Zero commitments will require dealing with CO2 emissions from agricultural and industrial sectors and from the production of blue and grey hydrogen during the transition time of switching to green hydrogen. Sequestration and shipping off of CO2 could be costly are not currently possible at large scale and are not sustainable. The use of CO2 by industry e.g. in construction materials and in food production processes can play a major role in addressing CO2 waste production from grey and blue hydrogen.<br/>In a Cradle-to-Cradle approach everything has a use. Is Wales missing out on creating and developing a new innovative industry around a CO2 circular economy?

This research project brought together members of the public from across the UK to participate in online workshops to explore:

• public understanding and perceptions of what reaching climate targets in the UK will mean for them individually and for society as a whole
• public attitudes and preferences towards the role that individual behaviour change should have in reaching net zero
• public perceptions of the easiest and toughest areas of change to help reach net zero
• public views on how they would prefer to engage with net zero policies and relevant initiatives that they feel could support the delivery of net zero

The EU and a number of its member states have now published hydrogen strategies and Europe continues to lead the way in the decarbonisation of its gas sector. In this latest OIES Energy Podcast James Henderson talks with Martin Lambert and Simon Schulte about their latest paper entitled “Contrasting European Hydrogen Pathways” which examines the plans in six major EU countries. They discuss the outlook for various forms of hydrogen supply contrasting the potential for green hydrogen from renewable energy with the outlook for blue hydrogen using steam-reforming of methane as well as hydrogen generated from surplus nuclear energy. They also examine the potential sources of demand considering existing use of hydrogen in industrial processes as well as the potential for hydrogen to displace hydrocarbons in the steel and cement industries. Finally the podcast also looks at the potential for imports of hydrogen and its distribution within Europe while also considering some key milestones that can provide indicators of how the region’s hydrogen plans are playing out.

This work investigates the impacts of variation management on the cost-optimal electricity system compositions in four regions with different pre-requisites for wind and solar generation. Five variation management strategies involving electric boilers batteries hydrogen storage low-cost biomass and demand-side management are integrated into a regional investment model that is designed to account for variability. The variation management strategies are considered one at a time as well as combined in four different system contexts. By investigating how the variation management strategies interact with each other as well as with different electricity generation technologies in a large number of cases this work support policy-makers in identifying variation management portfolios relevant to their context. It is found that electric boilers demand-side management and hydrogen storage increase the cost-optimal variable renewable electricity (VRE) investments if the VRE share is sufficiently large to reduce its marginal system value. However low-cost biomass and hydrogen storage are found to increase cost-optimal investments in wind power in systems with a low initial wind power share. In systems with low solar PV share variation management reduce the cost-optimal solar PV investments. In two of the regions investigated a combination of variation management strategies results in a stronger increase in VRE capacity than the sum of the single variation management efforts.

This work investigates the connection between electrification of the industry transport and heat sector and the integration of wind and solar power in the electricity system. The impact of combining electrification of the steel industry passenger vehicles and residential heat supply with flexibility provision is evaluated from a systems and sector perspective. Deploying a parallel computing approach to the capacity expansion problem the impact of flexibility provision throughout the north European electricity system transition is investigated. It is found that a strategic collaboration between the electricity system an electrified steel industry an electrified transport sector in the form of passenger electric vehicles (EVs) and residential heat supply can reduce total system cost by 8% in the north European electricity system compared to if no collaboration is achieved. The flexibility provision by new electricity consumers enables a faster transition from fossil fuels in the European electricity system and reduces thermal generation. From a sector perspective strategic consumption of electricity for hydrogen production and EV charging and discharging to the grid reduces the number of hours with very high electricity prices resulting in a reduction in annual electricity prices by up to 20%.

To become climate-neutral by 2050 Europe needs to transform its energy system which accounts for 75% of the EU's greenhouse gas emissions.  The EU strategies for energy system integration and hydrogen adopted today will pave the way towards a more efficient and interconnected energy sector driven by the twin goals of a cleaner planet and a stronger economy.<br/><br/>The two strategies present a new clean energy investment agenda in line with the Commission's Next Generation EU recovery package and the European Green Deal. The planned investments have the potential to stimulate the economic recovery from the coronavirus crisis. They create European jobs and boost our leadership and competitiveness in strategic industries which are crucial to Europe's resilience.

Horizon 2020 is the biggest EU Research and Innovation programme ever with nearly €80 billion of funding available over 7 years (2014 to 2020) – in addition to the private investment that this money will attract. It promises more breakthroughs discoveries and world-firsts by taking great ideas from the lab to the market.<br/>Horizon 2020 is the financial instrument implementing the Innovation Union a Europe 2020 flagship initiative aimed at securing Europe's global competitiveness.<br/><br/>Seen as a means to drive economic growth and create jobs Horizon 2020 has the political backing of Europe’s leaders and the Members of the European Parliament. They agreed that research is an investment in our future and so put it at the heart of the EU’s blueprint for smart sustainable and inclusive growth and jobs.<br/><br/>By coupling research and innovation Horizon 2020 is helping to achieve this with its emphasis on excellent science industrial leadership and tackling societal challenges. The goal is to ensure Europe produces world-class science removes barriers to innovation and makes it easier for the public and private sectors to work together in delivering innovation.<br/><br/>Horizon 2020 is open to everyone with a simple structure that reduces red tape and time so participants can focus on what is really important. This approach makes sure new projects get off the ground quickly – and achieve results faster.<br/><br/>The EU Framework Programme for Research and Innovation will be complemented by further measures to complete and further develop the European Research Area. These measures will aim at breaking down barriers to create a genuine single market for knowledge research and innovation.

As countries around the world rally behind net zero targets hydrogen is increasingly seen as a missing piece of the energy transformation puzzle to decarbonise harder-to-abate sectors. The possible pathway on which hydrogen might evolve still involves many uncertainties. With the growing momentum to establish a global hydrogen market comes the need for a deeper understanding of its broader effects including geopolitical aspects. IRENA has carried out an in-depth analysis of the geopolitics of hydrogen as part of the work of the Collaborative Framework on the Geopolitics of Energy Transformation (CF-GET). The report builds on IRENA’s substantial body of work in hydrogen and benefits from a wide range of expert input in the fields of energy and geopolitics.

This report considers whether and how hydrogen may disrupt future energy systems reflecting on many of the key themes discussed in the Global Commission’s report A New World – The Geopolitics of the Energy Transformation. The analysis offers insights into how countries and stakeholders can navigate the uncertainties and shape the development of hydrogen markets and outlines policy considerations to help mitigate the geopolitical risks and capitalise on opportunities. Some of the key findings of the report include:

• Hydrogen is part of a much bigger energy transition picture and its development and deployment strategies should not be considered in isolation.
• Setting the right priorities for hydrogen use will be essential for its rapid scale-up and long-term contribution to decarbonisation efforts.
• The 2020s could become the era of a big race for technology leadership as costs are likely to fall sharply with learning and scaling-up of needed infrastructure. Equipment manufacturing offers an opportunity to capture value in the coming years and decades.
• Hydrogen trade and investment flows will spawn new patterns of interdependence and bring shifts in bilateral relations.
• Countries with an abundance of low-cost renewable power could become producers of green hydrogen with commensurate geoeconomic and geopolitical consequences.
• Hydrogen could be an attractive avenue for fossil fuel exporters to help diversify their economies and develop new export industries.
• Supporting the advancement of renewable energy and green hydrogen in developing countries is critical for decarbonising the energy system and can contribute to global equity and stability.
• International co-operation will be necessary to devise a transparent hydrogen market with coherent standards and norms that contribute to climate change efforts meaningfully.

This is the tenth consecutive year of the World Energy Council’s (the Council) annual survey of key challenges and opportunities facing energy leaders in managing and shaping Energy Transitions. This year’s Issues Monitor report provides seven global maps six regional maps and fifty national maps.

These maps have been developed by analysing the responses of nearly 2300 energy leaders drawn from across the Council’s diverse and truly global energy community.

The Council’s Issues Monitor identifies the strategic energy landscape of specific countries and regions in the world through an analysis of 42 energy issues and 4 digitalisation-specific issues affecting the energy system. It provides a unique reality check and horizon scanning of persistent and emerging concerns involved in whole energy systems transition. This year’s report welcomes a significant increase in both the participation of global leaders (up over 75% from 1300 to nearly 2300) as well as the participation of 86 countries.

Each Issue Map provides a visual snapshot of the uncertainties and action priorities that energy policymakers CEOs and leading experts strive to address to shape and manage successful Energy

Transitions. Maps can be used in the following ways:

• To promote a shared understanding of successful Energy Transitions
• To appreciate and contrast regional variations to better understand differing priorities and areas of concern
• To follow the evolution of specific technology trends related to the energy sector

The Covid-19 pandemic has dealt a massive blow to countries around the world choking economies and transforming daily life for billions of people. This extraordinary disruption has significantly impacted the energy sector with worrying implications for clean energy transitions. Some key clean energy technologies have been encouragingly resilient to the effects of the crisis but so far there is little to suggest that the dramatic structural progress needed to achieve long-term climate and energy goals will happen in the current turmoil. Unprecedented action and leadership from governments companies and other real-world decision makers will be required to put the world more firmly on a sustainable long-term pathway. The energy sector must achieve dramatic sustained emissions reductions through policy investment and innovation measures across all energy sectors and technologies.

Building on Tracking Clean Energy Progress 2020  and other COVID-19 analysis this article takes stock of how the crisis has affected energy sectors and technologies thus far and explores the potential implications for clean energy transitions over the medium and longer term.

The Hydrogen Taskforce welcomes the opportunity to submit evidence to the Business Energy and

Industrial Strategy Committee’s inquiry into post-pandemic economic growth.

It is the Taskforce’s view that:

• Due to its various applications hydrogen is critical for the UK to reach net zero by 2050;
• The UK holds world-class advantages in hydrogen production distribution and application;
• Other economies are moving ahead in the development of this sector and the UK must respond;
• The post pandemic economic recovery planning should reflect the need to achieve deep decarbonisation and support wider objectives such as achieving net zero and levelling up the
• economy; and 
• The hydrogen sector is well-placed to play a key role in the UK’s economic recovery with the right policies and financial structures in place.

The Taskforce has defined a set of policy recommendations for Government which are designed to ensure that hydrogen can scale to meet the future demands of a net zero energy system:

• Development of a cross departmental UK Hydrogen Strategy within UK Government;
• Commit £1bn of capex funding over the next spending review period to hydrogen production storage and distribution projects;
• Develop a financial support scheme for the production of hydrogen in blending industry power and transport;
• Amend Gas Safety Management Regulations (GSMR) to enable hydrogen blending and take the next steps towards 100 per cent hydrogen heating through supporting public trials and
• mandating 100 per cent hydrogen-ready boilers by 2025; and
• Commit to the support of 100 Hydrogen Refuelling Stations (HRS) by 2025 to support the rollout of hydrogen transport.

This project provides evidence to identify the key innovation needs across the UK’s energy system to inform the prioritisation of public sector investment in low-carbon innovation including any future phases of the Department for Business Energy & Industrial Strategy (BEIS) Energy Innovation1 Programme. The BEIS Energy Innovation Programme aims to accelerate the commercialisation of innovative clean energy technologies and processes into the 2020s and 2030s. The current Programme with a budget of £505 million from 2015-2021 consists of six themes and invests in smart systems industry & CCS (Carbon Capture and Storage) the built environment nuclear renewables and support for energy entrepreneurs and green financing.



Vivid Economics was contracted to lead a consortium with technical expertise in each of the Energy Innovation Needs Assessment (EINA) priority areas. The programme relied on evidence from a programme of workshops with over 180 participants energy system modelling and detailed technical advice. Partners include the Carbon Trust E4tech Imperial College London and Fraser-Nash. The Energy Systems Catapult (ESC) provided analytical evidence using their Energy System Modelling Environment (ESME) to support an early pre-screening of technologies.



Innovations have been prioritised where there is a strong case for UK Government investment. The prioritisation in this report is based on evidence of the potential benefits to the UK via a lower cost energy system and larger export markets. We also consider whether there is a need for UK Government intervention in addition to private and international efforts.

 

A distinctive feature of this project is its focus on innovation that benefits the whole energy system. Internationally there are other efforts attempting to answer the question of where to target resources to maximise benefits from innovation2. In selecting priorities we identify innovations that can unlock value across electricity heat transport sectors and the rest of the economy.

The group concluded that the transition to Net Zero can and will occur and will leave a positive legacy for future generations. They examined the UK as a complex adaptive system and identified recommendations for accelerating progress and reducing the risks of failure. The Group recognised an opportunity for Sensitive Intervention Points (SIPs) coinciding with these recommendations pointing to opportunities to accelerate a transition towards Net Zero by exploiting socio-economic tipping points.

These included:

• Deepening public engagement through investments to support measures to lower ‘thresholds’ to behavioural change such as energy efficiency or dietary alternatives. This can form part of a public engagement strategy for Net Zero that educates the public involves people in decision-making and provides trusted information at key decision points
• Delivering social justice via a clear long-term vision for specific regions coupled with mechanisms that reward the private sector for building industries in otherwise deprived areas starting now
• Government leading on Net Zero by requiring any company meeting with ministers and secretaries of state to have a plan to reach net zero emissions
• Leveraging global dynamics by introducing a border carbon adjustment and consider forming bilateral and multilateral preferential trading arrangements for environmental goods and services
• Penalising emissions by committing in the UK’s NDC to sequester 10% of CO2 emissions generated by fossil fuels and industry by 2030
• Increasing business ambition by identifying businesses that shape industries – celebrate and elevate them
• Accelerating technology via Pathfinder cities that can deliver comprehensive steps towards Net Zero and demonstrate the interactions required across complex systems of low-carbon electricity heat and transport
• Redirecting capital flows by introducing Net zero aligned and transparent accounting and auditing
• Harnessing legal avenues by legislating all regulators to regard the Paris Agreement Sixth Carbon Budget and 2050 Net Zero target in their duties.

The hydrogen economy is a proposition for the distribution of energy by using hydrogen in order to potentially eliminate carbon emissions and end our reliance on fossil fuels. Some futuristic forecasters view the hydrogen economy as the ultimate carbon free economy. Hydrogen operated vehicles are on trial in many countries. The use of hydrogen as an energy source for buildings is in its infancy but research and development is evolving. Hydrogen is generally fed into devices called fuel cells to produce energy. A fuel cell is an electrochemical device that produces electricity and heat from a fuel (often hydrogen) and oxygen. Fuel cells have a number of advantages over other technologies for power generation. When fed with clean hydrogen they have the potential to use less fuel than competing technologies and to emit no pollution (the only bi-product being water). However hydrogen has to be produced and stored in the first instance. It is possible to generate hydrogen from renewable sources but the technology is still immature and the transformation is wasteful. The creation of a clean hydrogen production and distribution economy at a global level is very costly. Proponents of a world-scale hydrogen economy argue that hydrogen can be an environmentally cleaner source of energy to end-users particularly in transportation applications without release of pollutants (such as particulate matter) or greenhouse gases at the point of end use. Critics of a hydrogen economy argue that for many planned applications of hydrogen direct use of electricity or production of liquid synthetic fuels from locally-produced hydrogen and CO2 (e.g. methanol economy) might accomplish many of the same net goals of a hydrogen economy while requiring only a small fraction of the investment in new infrastructure. This paper reviews the hydrogen economy how it is produced and distributed. It then investigates the different types of fuel cells and identifies which types are relevant to the built environment both in residential and nonresidential sections. It concludes by examining what are the future plans in terms of implementing fuel cells in the built environment and discussing some of the needs of built environment sector.

According to the UK’s Committee on Climate Change the economically efficient achievement of Government’s legally-binding carbon-reduction target will require full decarbonisation of all heat in buildings and the decarbonisation of most industrial heat over the next 20 to 30 years (BEIS 2018). This goliath task is not unprecedented. Indeed the scale of this transition is similar to the UK’s former transition from coal to natural gas heating. Albeit the rate of transition away from natural gas will certainly need to be greater than the rate of the transition toward natural gas to achieve net zero greenhouse gas emissions by 2050.<br/><br/>At present Government’s commitment stands in sharp contrast with its inaction on heat decarbonisation to date. Under pressure to progress this agenda Government has charged the Clean Heat Directorate with the task of outlining the process for determining the UK’s long-term heat policy framework to be published in the ‘Roadmap for policy on heat decarbonisation’ in the summer of 2020 (BEIS 2017). This report resulting from one of six EPSRC-funded secondments is designed to support early thinking on the roadmap by answering the research question: How can ‘Transitions’ research informs the roadmap for governing the UK’s heating transition?<br/><br/>‘Transitions’ research is an interdisciplinary field of study within the Social Sciences and Humanities that investigates the co-evolution of social and technological systems (such as the UK heating system) and the dynamics by which fundamental change in these systems occur. To investigate what insights this area of research may hold for the governance of the UK’s heat transition a systematic literature review was conducted focusing specifically on past and ongoing heat transitions across Europe.<br/><br/>The review uncovered learnings about the role of path dependency; power and politics; complexity; cross-sector interactions; multi-level governance; and intermediaries in shaping non-linear transitions toward renewable heat. This report illustrates each learning with real-world examples from case studies undertaken by Transitions researchers and concludes with a long list of policy and process-oriented governance recommendations for the UK Government.

The Sixth Carbon Budget report is based on an extensive programme of analysis consultation and consideration by the Committee and its staff building on the evidence published last year for our Net Zero advice. In support of the advice in this report we have also produced:

• A Methodology Report setting out the evidence and methodology behind the scenarios.
• A Policy Report setting out the changes to policy that could drive the changes necessary particularly over the 2020s.
• All the charts and data behind the report as well as a separate dataset for the Sixth Carbon Budget scenarios which sets out more details and data on the pathways than can be included in this report.
• A public Call for Evidence several new research projects three expert advisory groups and deep dives into the roles of local authorities and businesses.

Our recommended pathway requires a 78% reduction in UK territorial emissions between 1990 and 2035. In effect bringing forward the UK’s previous 80% target by nearly 15 years.

As part of reducing carbon emissions governments across the world are working on measures to transition sectors of the economy away from fossil fuels. The socio-technical regimes being constructed around the energy transition can encourage energy centralisation and constrain actor engagement without proper policy and planning. The energy transition is liable to have significant impacts across all of society but less attention has been given to the role of democratic participation and decision-making in the energy system during this time. Using the energy democracy framework developed by Kacper Szulecki we employ content analysis to investigate how Australia’s renewable hydrogen strategies at the Commonwealth and state levels engage with the broader objective of democratising energy systems. Based on our findings we recommend ways to support a renewable hydrogen regime in Australia in line with the principles of energy democracy such as community engagement built-in participation popular sovereignty community-level agency and civic ownership. This study provides a perspective on the energy transition that is often overlooked and a reminder to policymakers that the topology of an energy transition can take many forms.

Hydrogen has been used as an industrial chemical for more than 100 years. Today hydrogen is used to manufacture ammonia and hence fertilizers as well as methanol and hydrogen peroxide both vital feedstocks for a wide variety of different chemical products. Furthermore in oil refineries hydrogen is used for the processing of intermediate products as well as to increase the hydrogen contents of the final products that are used propel the vehicles. However hydrogen has recently achieved new attention for its capabilities in reducing carbon emissions to the atmosphere. Producing hydrogen via low or totally carbon-free ways and using this “good” low-carbon hydrogen to replace hydrogen with a larger carbon footprint we can reduce carbon emissions. Furthermore using renewable electricity and captured carbon we can synthesise many such chemical products that are currently produced from fossil raw materials. This “Power-to-X” (P2X) is often seen as the eventual incarnation of the hydrogen economy. In addition the progress in technology both in hydrogen fuel cells and in polymer electrolyte electrolysers alike has increased their efficiencies.<br/>Furthermore production costs of renewable electricity by wind or solar power have lowered significantly. Thus cost of “good” hydrogen has also decreased markedly and production volumes are expected to increase rapidly. For these reasons many countries have raised interests in “good” hydrogen and have created roadmaps and strategies for their involvement in hydrogen. Hydrogen plays a key role also in combating climate change and reaching Finland's national goal of carbon neutrality by 2035. In recent years many clean hydrogen and P2X production methods have developed significantly and become commercially viable.<br/>This report was produced by a team of VTT experts on hydrogen and hydrogen-related technologies. The focus is in an outlook for low-carbon H2 production H2 utilization for green chemicals and fuels as well as storage transport and end-use especially during the next 10 years in Finland in connection to renewed EU regulations. This roadmap is expected to serve as the knowledge-base for further work such as shaping the hydrogen policy for Finland and determining the role of hydrogen in the national energy and climate policy.

Many countries including China have implemented supporting policies to promote the commercialized application of green hydrogen and hydrogen fuel cells. In this study a system dynamics (SD) model is proposed to study the evolution of hydrogen demand in China from the petroleum refining industry the synthetic ammonia industry and the vehicle market. In the model the impact from the macro-environment hydrogen fuel supply and construction of hydrogen facilities is considered to combine in incentives for supporting policies. To further formulate the competitive relationship in the vehicle market the Lotka–Volterra (LV) approach is adopted. The model is verified using published data from 2003 to 2017. The model is also used to forecast China’s hydrogen demand up to the year of 2030 under three different scenarios. Finally some forward-looking guidance is provided to policy makers according to the forecasting results.

This paper provides a critical study of current Australian and leading international policies aimed at supporting electrical energy storage for stationary power applications with a focus on battery and hydrogen storage technologies. It demonstrates that global leaders such as Germany and the U.S. are actively taking steps to support energy storage technologies through policy and regulatory change. This is principally to integrate increasing amounts of intermittent renewable energy (wind and solar) that will be required to meet high renewable energy targets. The relevance of this to the Australian energy market is that whilst it is unique it does have aspects in common with the energy markets of these global leaders. This includes regions of high concentrations of intermittent renewable energy (Texas and California) and high penetration rates of residential solar photovoltaics (PV) (Germany). Therefore Australian policy makers have a good opportunity to observe what is working in an international context to support energy storage. These learnings can then be used to help shape future policy directions and guide Australia along the path to a sustainable energy future.

Global warming and fossil fuel depletion have necessitated alternative sources of energy. Biomass is a promising fuel source because it is renewable and can be carbon negative even without carbon capture and storage. This study considers biomass as a clean renewable source for transportation fuels. An Aspen Plus process simulation model was built of a biomass gasification biorefinery with Fischer-Tropsch (FT) synthesis of liquid fuels. A GaBi life cycle assessment model was also built to determine the environmental impacts using a cradle-to-grave approach. Three different product pathways were considered: Fischer-Tropsch synthetic diesel hydrogen and electricity. An offgas autothermal reformer with a recycle loop was used to increase FT product yield. Different configurations and combinations of biorefinery products are considered. The thermal efficiency and cost of production of the FT liquid fuels are analyzed using the Aspen Plus process model. The greenhouse gas emissions profitability and mileage per kg biomass were compared. The mileage traveled per kilogram biomass was calculated using modern (2019-2021) diesel electric and hydrogen fuel cell vehicles. The overall thermal efficiency was found to be between 20-41% for FT fuels production between 58-61% for hydrogen production and around 25-26% for electricity production for this biorefinery. The lowest production costs were found to be $3.171/gal of FT diesel ($24.304/GJ) $1.860/kg of H2 ($15.779/GJ) and 13.332¢/kWh for electricity ($37.034/GJ). All configurations except one had net negative carbon emissions over the life cycle of the biomass. This is because carbon is absorbed in the trees initially and some of the carbon is sequestered in ash and unconverted char from the gasification process furthermore co-producing electricity while making transportation fuel offsets even more carbon emissions. Compared to current market rates for diesel hydrogen and electricity the most profitable biorefinery product is shown to be hydrogen while also having net negative carbon emissions. FT diesel can also be profitable but with a slimmer profit margin (not considering government credits) and still having net negative carbon emissions. However our biorefinery could not compete with current commercial electricity prices in the US. As oil hydrogen and electricity prices continue to change the economics of the biorefinery and the choice product will change as well. For our current biorefinery model hydrogen seems to be the most promising product choice for profit while staying carbon negative while FT diesel is the best choice for sequestering the most carbon and still being profitable. All code and data are given.

The Department of Energy (DOE) Hydrogen Program Plan (the Program Plan or Plan) outlines the strategic high-level focus areas of DOE’s Hydrogen Program (the Program). The term Hydrogen Program refers not to any single office within DOE but rather to the cohesive and coordinated effort of multiple offices that conduct research development and demonstration (RD&D) activities on hydrogen technologies. This terminology and the coordinated efforts on hydrogen among relevant DOE offices have been in place since 2004 and provide an inclusive and strategic view of how the Department coordinates activities on hydrogen across applications and sectors. This version of the Plan updates and expands upon previous versions including the Hydrogen Posture Plan and the DOE Hydrogen and Fuel Cells Program Plan and provides a coordinated high-level summary of hydrogen related activities across DOE.



The 2006 Hydrogen Posture Plan fulfilled the requirement in the Energy Policy Act of 2005 (EPACT 2005) that the Energy Secretary transmit to Congress a coordinated plan for DOE’s hydrogen and fuel cell activities. For historical context the original Posture Plan issued in 2004 outlined a coordinated plan for DOE and the U.S. Department of Transportation to meet the goals of the Hydrogen Fuel Initiative (HFI) and implement the 2002 National Hydrogen Energy Technology Roadmap. The HFI was launched in 2004 to accelerate research development and demonstration (RD&D) of hydrogen and fuel cell technologies for use in transportation electricity generation and portable power applications. The Roadmap provided a blueprint for the public and private efforts required to fulfill a long-term national vision for hydrogen energy as outlined in A National Vision of America’s Transition to a Hydrogen Economy—to 2030 and Beyond. Both the Roadmap and the Vision were developed out of meetings involving DOE industry academia non-profit organizations and other stakeholders. The Roadmap the Vision the Posture Plans the 2011 Program Plan and the results of key stakeholder workshops continue to form the underlying basis for this current edition of the Program Plan.



This edition of the Program Plan reflects the Department’s focus on conducting coordinated RD&D activities to enable the adoption of hydrogen technologies across multiple applications and sectors. It includes content from the various plans and documents developed by individual offices within DOE working on hydrogen-related activities including: the Office of Fossil Energy's Hydrogen Strategy: Enabling a Low Carbon Economy the Office of Energy Efficiency and Renewable Energy’s Hydrogen and Fuel Cell Technologies Office Multi-year RD&D Plan the Office of Nuclear Energy’s Integrated Energy Systems 2020 Roadmap and the Office of Science’s Basic Research Needs for the Hydrogen Economy. Many of these documents are also in the process of updates and revisions and will be posted online.



Through this overarching document the reader will gain information on the key RD&D needs to enable the largescale use of hydrogen and related technologies—such as fuel cells and turbines—in the economy and how the Department’s various offices are addressing those needs. The Program will continue to periodically revise the Plan along with all program office RD&D plans to reflect technological progress programmatic changes policy decisions and updates based on stakeholder input and reviews.

This document summarizes current hydrogen technologies and communicates the U.S. Department of Energy (DOE) Office of Fossil Energy's (FE's) strategic plan to accelerate research development and deploymnet of hydrogen technologies in the United States. It also describes ongoing FE hydrogen-related research and development (R&D). Hydrogen from fossil fuels is a versatile energy carrier and can play an important role in the transition to a low-carbon economy.

In an integrated energy system hydrogen can support the decarbonisation of industry transport power generation and buildings across Europe. The EU Hydrogen Strategy addresses how to transform this potential into reality through investments regulation market creation and research and innovation.

Hydrogen can power sectors that are not suitable for electrification and provide storage to balance variable renewable energy flows but this can only be achieved with coordinated action between the public and private sector at EU level. The priority is to develop renewable hydrogen produced using mainly wind and solar energy. However in the short and medium term other forms of low-carbon hydrogen are needed to rapidly reduce emissions and support the development of a viable market.

This gradual transition will require a phased approach:

• From 2020 to 2024 we will support the installation of at least 6 gigawatts of renewable hydrogen electrolysers in the EU and the production of up to one million tonnes of renewable hydrogen.
• From 2025 to 2030 hydrogen needs to become an intrinsic part of our integrated energy system with at least 40 gigawatts of renewable hydrogen electrolysers and the production of up to ten million tonnes of renewable hydrogen in the EU.
• From 2030 to 2050 renewable hydrogen technologies should reach maturity and be deployed at large scale across all hard-to-decarbonise sectors.
• To help deliver on this Strategy the Commission is launched the European Clean Hydrogen Alliance with industry leaders civil society national and regional ministers and the European Investment Bank. The Alliance will build up an investment pipeline for scaled-up production and will support demand for clean hydrogen in the EU.

To target support at the cleanest available technologies the Commission will work to introduce common standards terminology and certification based on life-cycle carbon emissions anchored in existing climate and energy legislation and in line with the EU taxonomy for sustainable investments. The Commission will propose policy and regulatory measures to create investor certainty facilitate the uptake of hydrogen promote the necessary infrastructure and logistical networks adapt infrastructure planning tools and support investments in particular through the Next Generation EU recovery plan.

This technical report accompanies the ‘Net Zero’ advice report which is the Committee’s recommendation to the UK Government and Devolved Administrations on the date for a net-zero emissions target in the UK and revised long-term targets in Scotland and Wales.<br/>The conclusions in our advice report are supported by detailed analysis that has been carried out for each sector of the economy plus consideration of F-gas emissions and greenhouse gas removals. The purpose of this technical report is to lay out that analysis.
