Policy & Socio-Economics

A global transition to hydrogen fuel offers major opportunities to decarbonise a range of different energyintensive sectors from large-scale electricity generation through to heating in homes. Hydrogen can be deployed as an energy source in two distinct ways in electrochemical fuel cells and via combustion. Combustion seems likely to be a major pathway given that it requires only incremental technological change. The use of hydrogen is not however without side-effects and the widely claimed benefit that only water is released as a by-product is only accurate when it is used in fuel cells. The burning of hydrogen can lead to the thermal formation of nitrogen oxides (NOx – the sum of NO + NO2) via a mechanism that also applies to the combustion of fossil fuels. NO2 is a key air pollutant that is harmful in its own right and is a precursor to other pollutants of concern such as fine particulate matter and ozone. Minimising NOx as a by-product from hydrogen boilers and engines is possible through control of combustion conditions but this can lead to reduced power output and performance. After-treatment and removal of NOx is possible but this increases cost and complexity in appliances. Combustion applications therefore require optimisation and potentially lower hydrogen-specific emissions standards if the greatest air quality benefits are to derive from a growth in hydrogen use

In recent years increasing concerns regarding the energy costs and environmental effects of urban motorcycle use have spurred the development of hydrogen-electric motorcycles in Taiwan. Although gasoline-powered motorcycles produce substantial amounts of exhaust and noise pollution hydrogen-electric motorcycles are highly energy-efficient relatively quiet and produce zero emissions features that suggest their great potential to reduce the problems currently associated with the use of motorcycles in city environments. This study identified the significant external variables that affect consumers’ purchase intentions toward using hydrogen-electric motorcycles. A questionnaire method was employed with a total of 300 questionnaires distributed and 233 usable questionnaires returned yielding a 78% overall response rate. Structural equation modeling (SEM) was applied to test the research hypothesis. The research concluded that (1) product knowledge positively influenced purchase intentions but negatively affected the perceived risk; (2) perceived quality via hydrogen-electric motorcycles positively influenced the perceived value but negatively affected the perceived risk; (3) perceived risk negatively affected the perceived value; and (4) the perceived value positively affected purchase intentions. This study can be used as a reference for motorcycle manufacturers when planning their marketing strategies.

In this report we focus on the fundamentals of energy and climate policy as reformulated in the EU Green Deal. The 2022 edition includes updates following the publication of the Fit for 55 Package and the EU Hydrogen and Decarbonised Gas Markets Package. The reader is guided through the landscape of EU climate and energy policy. Starting with the big picture of the foundations of energy and climate policy we then move to discussing in more detail European climate policy security of supply and energy networks. We continue with energy wholesale and retail markets and finish with a closer look at energy innovation. Each chapter is divided into several sections aiming to give the reader a broad overview of the areas of climate and energy policy that are impacted by the EU Green Deal. The references at the end of each section serve as suggestions for further reading on each topic.

The emerging energy transition is particularly described as a move towards a cleaner lower-carbon system. In the context of the global shift towards sustainable energy sources this paper reviews the potential and roadmap for hydrogen energy as a crucial component of the clean energy landscape. The primary objective is to present a comprehensive literature overview illuminating key themes trends and research gaps in the scientific discourse concerning hydrogen production and energy policy. This review focuses particularly on specified geographic contexts with an emphasis on understanding the unique energy policies related to renewable energy in Brazil Austria and Germany. Given their distinct social systems and developmental stages this paper aims to delineate the nuanced approaches these countries adopt in their pursuit of renewable energy and the integration of hydrogen within their energy frameworks. Brazil exhibits vast renewable energy potential particularly in wind and solar energy sectors positioning itself for substantial growth in the coming years. Germany showcases a regulatory framework that promotes innovation and technological expansion reflecting its highly developed social system and commitment to transitioning away from fossil fuels. Austria demonstrates dedication to decarbonization particularly through the exploration of biomethane for residential heating and cooling.

Renewable hydrogen is considered key in the transition towards a carbon-neutral future. This is due to its spatio-temporal storage and sector coupling potential which has seen it referred to as energy vector. However many unresolved issues remain regarding hydrogen's large-scale deployment e.g. least-cost production optimal facility siting and overall implications on power and energy systems. Expansion planning provides an option to study these issues in the holistic context of energy systems. To this end this article presents a comprehensive review on state-of-the-art expansion planning models that consider integrated power natural gas and hydrogen systems. We cluster the existing literature in terms of modelling themes and scope study the applied systematic modelling characteristics and conduct an in-depth analysis of the technical model features regarding hydrogen technologies and natural gas infrastructure. Finally we identify and discuss research gaps in the existing literature.

On this weeks episode the team discuss the Hydrogen Council the global stakeholder forum that has been at the forefront of efforts to advance the role of hydrogen and fuel cell technologies globally. We are excited to have as our guests Pierre-Etienne Franc Vice President for the Hydrogen Energy World Business Unit at Air Liquide and Stephan Herbst General Manager at Toyota Motor Europe. On the show we discuss why Air Liquide and Toyota decided to engage with the Council its strategy vision and perspective on the role that hydrogen can play in the energy transition and how companies can work with policymakers to enable this process. All this and more on the show!

The European Commission aims to establish green hydrogen produced through electrolysis using renewable electricity and in a transition phase hydrogen produced in a low-carbon process or blue hydrogen. In an extensive cost analysis for Germany up to 2050 based on scenario data and a component-based learning rate approach we find that blue hydrogen is likely to establish itself as the most cost-effective option and not only as a medium-term low-carbon alternative. We find that expected CO2 prices below €480/tCO2 have a limited impact on the economic feasibility of electrolysis and show that substantial increases in excise tax on natural gas could lead blue hydrogen to reach a sufficient cost level for electrolysed hydrogen. Unless alternatives for green hydrogen supply through infrastructure and imports become available at lower cost electrolysed hydrogen may require long-term subsidies. As blue hydrogen comprises fugitive methane emissions and financing needs for green hydrogen support have implications for society and competition in the internal market we suggest that policymakers rely on hydrogen for decarbonising only essential energy applications. We recommend further investigations into the cost of hydrogen infrastructure and import options as well as efficient subsidy frameworks.

The Low Carbon Hydrogen Standard sets a maximum threshold for the amount of greenhouse gas emissions allowed in the production process for hydrogen to be considered ‘low carbon hydrogen’. Compliance with the standard will help ensure new low carbon hydrogen production makes a direct contribution to our carbon reduction targets.

This guidance sets out the methodology for calculating the emissions associated with hydrogen production and the steps producers should take to prove that the hydrogen they produce is compliant with the standard.

It is for use by hydrogen producers seeking support from government schemes and policies that have adopted the standard.

The standard requires hydrogen producers to:

• meet a GHG emissions intensity of 20g CO2e/MJLHV of produced hydrogen or less for the hydrogen to be considered low carbon
• calculate their greenhouse gas (GHG) emissions up to the ‘point of production’
• set out a risk mitigation plan for fugitive hydrogen emissions
• meet additional requirements for the use of biogenic inputs where relevant and as appropriate for the feedstock source and classification

On this episode the EAH team discusses the role of hydrogen in the energy transition with Michael Liebreich Chairman and CEO of Liebreich Associates. Michael is an acknowledged thought leader on clean energy mobility technology climate sustainability and finance. He is the founder and senior contributor to Bloomberg New Energy Finance a member of numerous industry governmental and multilateral advisory boards an angel investor a former member of the board of Transport for London and an Advisor to the UK Board of Trade.

Gaseous fuels with low life-cycle emissions of greenhouse gases (GHG) play a prominent role in the European Union’s (EU) decarbonization plans. Renewable and low-GHG hydrogen are highlighted in the ambitious goals for a cross-sector hydrogen economy laid out in the European Commission’s Hydrogen Strategy. Renewable hydrogen and biomethane are given strong production incentives in the Commission’s proposed revision to the Renewable Energy Directive (REDII). The EU uses life-cycle analysis (LCA) to determine whether renewable gas pathways meet the GHG reduction thresholds for eligibility in the REDII. This study aims to support European policymakers with a better understanding of the uncertainties regarding gaseous fuels’ roles in meeting climate goals. Life-cycle GHG analysis is complex and differences in methodology as well as data inputs and assumptions can spell the difference between a renewable gas pathway qualifying or not for REDII eligibility at the 50% to 80% GHG reduction level. It is thus important for European policymakers to use robust LCA to ensure that policy only supports gas pathways consistent with a vision of deep decarbonization. For this purpose we conduct sensitivity analysis of the life-cycle GHG emissions of a number of low-GHG gas pathways including biomethane produced from four feedstocks: wastewater sludge manure landfill gas (LFG) and silage maize; and hydrogen produced from eight sources: natural gas combined with carbon capture and storage (CCS) coal with CCS biomass gasification renewable electricity 2030 EU grid electricity wastewater sludge biomethane manure biomethane and LFG biomethane. For each pathway we estimate the life-cycle GHG intensity using a default central case identify key parameters that strongly affect the fuel’s GHG intensity and conduct a sensitivity analysis by changing these key parameters according to the range of possible values collected from the literature. Figure ES1 summarizes the full range of possible GHG intensities for each gaseous pathway we analyzed in this study—biomethane is depicted in the top figure and hydrogen is shown in the bottom. The bars represent the GHG intensity of the central case and vertical error bars indicate the maximum and minimum GHG intensity of each pathway according to our sensitivity analysis. The dotted orange horizontal line illustrates the fossil comparator which is 94 grams of carbon dioxide equivalent per megajoule (gCO2e/MJ) for transport fuels in the REDII. The dotted yellow line represents the GHG intensity of a 65% GHG reduction goal for biomethane used in the transportation sector or 70% GHG reduction for hydrogen. Pathways are situated from left to right in increasing order of GHG intensity of the central case. Comparing the central cases of the four biomethane pathways the waste-based biomethane pathways generally have negative GHG intensity. However considering the uncertainty in these GHG intensities manure biomethane might have more limited carbon reduction potential in the 100-year timeframe if methane leakage from its production process is high. In contrast wastewater sludge biomethane and LFG biomethane even after accounting for uncertainties retain relatively low GHG emissions. On the other hand biomethane produced from silage maize can have much higher emissions; in the central case we find that silage maize biogas only reduces GHG emissions by 30% relative to the fossil comparator—the low carbon reduction potential is due to the significant emissions emerging from direct and indirect land use change involved in growing maize. Taking into account the variation in assumptions silage maize biomethane can be worse for the climate than fossil fuels.

The goal of the European energy policy is to achieve climate neutrality. The long-term energy strategies of various European countries include additional targets such as the diversification of energy sources maintenance of security of supply and reduction of import dependency. When optimizing energy systems these strategic policy targets are often only considered in a rudimentary manner and thus the understanding of the corresponding interdependencies is lacking. Moreover hydrogen is considered as a key component of a fully decarbonized energy system but its role in the power sector remains unclear due to the low round-trip efficiencies. This study reveals how fully decarbonized European power systems can benefit from hydrogen in terms of overall system costs and the achievement of strategic policy targets. We analyzed a broad spectrum of scenarios using an energy system optimization model and varied model constraints that reflect strategic policy targets. Our results are threefold. First compared to power systems without hydrogen systems using hydrogen realize savings of 14–16% in terms of the total system costs. Second the implementation of a hydrogen infrastructure reduces the number of infeasible scenarios when structural policy targets are considered within the power system. Third the role of hydrogen is highly diverse at a national level. Particularly in countries with low renewable energy potential hydrogen plays a crucial role. Here high levels of self-sufficiency and security of supply are achieved by deploying hydrogen-based power generation of up to 46% of their annual electricity demand realized via imports of green hydrogen.

Worldwide energy systems are experiencing a transition to more sustainable systems. According to the Hydrogen Roadmap Europe (FCH EU 2019) hydrogen will play an important role in future energy systems due to its ability to support sustainability goals and will account for approximately 13% of the total energy mix in the coming future. Correct hydrogen supply chain (HSC) planning is therefore vital to enable a sustainable transition. However due to the operational characteristics of the HSC its planning is complicated. Renewable hydrogen supply can be diverse: Hydrogen can be produced de-centrally with renewables such as wind and solar energy or centrally by using electricity generated from a hydro power plant with a large volume. Similarly demand for hydrogen can also be diverse with many new applications such as fuels for fuel cell electrical vehicles and electricity generation feedstocks in industrial processes and heating for buildings. The HSC consists of various stages (production storage distribution and applications) in different forms with strong interdependencies which further increase HSC complexity. Finally planning of an HSC depends on the status of hydrogen adoption and market development and on how mature technologies are and both factors are characterised by high uncertainties. Directly adapting the traditional approaches of supply chain planning for HSCs is insufficient. Therefore in this study we develop a planning matrix with related planning tasks leveraging a systematic literature review to cope with the characteristics of HSCs. We focus only on renewable hydrogen due to its relevance to the future low-carbon economy. Furthermore we outline an agenda for future research from the supply chain management perspective in order to support HSC development considering the different phases of HSCs adoption and market development.

As result of the adverse effects caused by climate change the nations have decided to accelerate the transition of the energy matrix through the use of non-conventional sources free of polluting emissions. One of these alternatives is green hydrogen. In this context Chile stands out for the exceptional climate that makes it a country with a lot of renewable resources. Such availability of resources gives the nation clear advantages for hydrogen production strong gusts of wind throughout the country the most increased solar radiation in the world lower cost of production of electrical supplies among others. Due to this the nation would be between the lowest estimated cost for hydrogen production i.e. 1.5 USD/kg H2 approximately scenario that would place it as one of the cheapest green hydrogen producer in the world.

Energy networks are the systems of pipes and wires by which different energy vectors are transported from where they are produced to where they are needed. As such these networks are central to facilitating countries’ moves away from a reliance on fossil fuels to a system based around the efficient use of renewable and other low carbon forms of energy. In this review we highlight the challenges facing energy networks from this transition in a sample of key high income countries. We identify the technical and other innovations being implemented to meet these challenges and describe some of the new policy and regulatory developments that are incentivising the required changes. We then review evidence from the literature about the benefits of moving to a more integrated approach based on the concept of a Multi-Vector Energy Network (MVEN). Under this approach the different networks are planned and operated together to achieve greater functionality and performance than simply the sum of the individual networks. We find that most studies identify a range of benefits from an MVEN approach but that these findings are based on model simulations. Further work is therefore needed to verify whether the benefits can be realised in practice and to identify how any risks can be mitigated.

Hydrogen may play a significant part in sustainable energy transition. This paper discusses the sociotechnical interactions that are driving and hindering development of hydrogen value chains in Norway. The study is based on a combination of qualitative and quantitative methods. A multi-level perspective (MLP) is deployed to discuss how exogenous trends and uncertainties interact with processes and strategies in the national energy system and how this influences the transition potential associated with Norwegian hydrogen production. We explore different transition pathways towards a low-emission society in 2050 and find that Norwegian hydrogen production and its deployment for decarbonization of maritime and heavy-duty transport decarbonisation of industry and flexibility services may play a crucial role. Currently the development is at a branching point where national coordination is crucial to unlock the potential. The hybrid approach provides new knowledge on underlying system dynamics and contributes to the discourse on pathways in transition studies.

Under the requirements of China's strategic goal of "carbon peaking and carbon neutrality" as a renewable clean and efficient secondary energy source hydrogen benefits from abundant resources a wide variety of sources a high combustion calorific value clean and non-polluting various forms of utilization energy storage mediums and good security etc. It will become a realistic way to help energy transportation petrochemical and other fields to achieve deep decarbonization and will turn into an important replacement energy source for China to build a modern clean energy system. It is clear that accelerating the development of hydrogen energy has become a global consensus. In order to provide a theoretical support for the accelerated transformation of hydrogen-related industries and energy companies and provide a basis and reference for the construction of "Hydrogen Energy China" this paper describes main key technological progresses in the hydrogen industry chain such as hydrogen production storage transportation and application. The status and development trends of hydrogen industrialization are analyzed and then the challenges faced by the development of the hydrogen industry are discussed. At last the development and future of the hydrogen industry are prospected. The following conclusions are achieved. (1) Hydrogen technologies of our country will become mature and enter the road of industrialization. The whole industry chain system of the hydrogen industry is gradually being formed and will realize the leap-forward development from gray hydrogen blue hydrogen to green hydrogen. (2) The overall development of the entire hydrogen industry chain such as hydrogen production storage and transportation fuel cells hydrogen refueling stations and other scenarios should be accelerated. Besides in-depth integration and coordination with the oil and gas industry needs more attention which will rapidly promote the high-quality development of the hydrogen industry system. (3) The promotion and implementation of major projects such as "north-east hydrogen transmission" "west-east hydrogen transmission" "sea hydrogen landing" and utilization of infrastructures such as gas filling stations can give full play to the innate advantages of oil and gas companies in industrial chain nodes such as hydrogen production and refueling etc. which can help to achieve the application of "oil gas hydrogen and electricity" four-station joint construction form a nationwide hydrogen resource guarantee system and accelerate the planning and promotion of the "Hydrogen Energy China" strategy.

Delivering low-carbon heat will require the substitution of natural gas with low-carbon alternatives such as electricity and hydrogen. The objective of this paper is to develop a method to soft-link two advanced investment-optimising energy system models RTN (Resource-Technology Network) and WeSIM (Whole-electricity System Investment Model) in order to assess cost-efficient heat decarbonisation pathways for the UK while utilising the respective strengths of the two models. The linking procedure included passing on hourly electricity prices from WeSIM as input to RTN and returning capacities and locations of hydrogen generation and shares of electricity and hydrogen in heat supply from RTN to WeSIM. The outputs demonstrate that soft-linking can improve the quality of the solution while providing useful insights into the cost-efficient pathways for zero-carbon heating. Quantitative results point to the cost-effectiveness of using a mix of electricity and hydrogen technologies for delivering zero-carbon heat also demonstrating a high level of interaction between electricity and hydrogen infrastructure in a zero-carbon system. Hydrogen from gas reforming with carbon capture and storage can play a significant role in the medium term while remaining a cost-efficient option for supplying peak heat demand in the longer term with the bulk of heat demand being supplied by electric heat pumps.

Hydrogen as fuel has been a promising technology toward climate change mitigation efforts. To this end in this paper we analyze the contribution of hydrogen technology to our future environmental goals. It is assumed that hydrogen is being produced in higher efficiency across time and this is simulated on Global Change Assessment Model (GCAM). The environmental restrictions applied are the expected emissions representative concentration pathways (RCP) 2.6 4.5 and 6.0. Our results have shown increasing hydrogen production as the environmental constraints become stricter and hydrogen more efficient in being produced. This increase has been quantified and provided on open access as Supporting Information to this manuscript.

Although hydrogen has been used in industry for many years as a chemical commodity its use as a fuel or energy carrier is relatively new and expert knowledge about its associated risks is neither complete nor consensual. Public awareness of hydrogen energy and attitudes towards a future hydrogen economy are yet to be systematically investigated. This paper opens by discussing alternative conceptualisations of risk then focuses on issues surrounding the use of emerging technologies based on hydrogen energy. It summarises expert assessments of risks associated with hydrogen. It goes on to review debates about public perceptions of risk and in doing so makes comparisons with public perceptions of other emergent technologies—Carbon Capture and Storage (CCS) Genetically Modified Organisms and Food (GM) and Nanotechnology (NT)—for which there is considerable scientific uncertainty and relatively little public awareness. The paper finally examines arguments about public engagement and "upstream" consultation in the development of new technologies. It is argued that scientific and technological uncertainties are perceived in varying ways and different stakeholders and different publics focus on different aspects or types of risk. Attempting to move public consultation further "upstream" may not avoid this because the framing of risks and benefits is necessarily embedded in a cultural and ideological context and is subject to change as experience of the emergent technology unfolds.

One of the strategic goals of developed countries is to significantly increase the share of renewable energy sources in electricity generation. However the process may be hindered by e.g. the storage and transport of energy from renewable sources. The European Union countries see the development of the hydrogen economy as an opportunity to overcome this barrier. Therefore since 2020 the European Union has been implementing a hydrogen strategy that will increase the share of hydrogen in the European energy mix from the current 2 percent to up to 13–14 percent by 2050. In 2021 following the example of other European countries the Polish government adopted the Polish Hydrogen Strategy until 2030 with an outlook until 2040 (PHS). However the implementation of the strategy requires significant capital expenditure and infrastructure modernisation which gives rise to question as to whether Poland is likely to achieve the goals set out in the Polish Hydrogen Strategy and European Green Deal. The subject of the research is an analysis of the sources of financing for the PHS against the background of solutions implemented by the EU countries and a SWOT/TOWS analysis on the hydrogen economy in Poland. The overall result of the SWOT/TOWS analysis shows the advantage of strengths and related opportunities. This allows for a positive assessment of the prospects for the hydrogen economy in Poland. Poland should continue its efforts to take advantage of the external factors (O/S) such as EU support an increased price competitiveness of hydrogen and the emergence of a competitive cross-border hydrogen market in Europe. At the same time the Polish authorities should not forget about the weaknesses and threats that may inhibit the development of the domestic hydrogen market. It is necessary to modernise the infrastructure; increase the share of renewable energy sources in hydrogen production; increase R&D expenditure and in particular to complete the negotiations related to the adoption of the Fit for 55 package.

The paper explores options for a 2050 carbon free energy future for India. Onshore wind and solar sources are projected as the dominant primary contributions to this objective. The analysis envisages an important role for so-called green hydrogen produced by electrolysis fueled by these carbon free energy sources. This hydrogen source can be used to accommodate for the intrinsic variability of wind and solar complementing opportunities for storage of power by batteries and pumped hydro. The green source of hydrogen can be used also to supplant current industrial uses of grey hydrogen produced in the Indian context largely from natural gas with important related emissions of CO2. The paper explores further options for use of green hydrogen to lower emissions from otherwise difficult to abate sectors of both industry and transport. The analysis is applied to identify the least cost options to meet India’s zero carbon future.

This paper presents two different scenarios for the energy system of the Netherlands that achieve the Dutch government’s national target of near net-zero greenhouse gas emissions in 2050. Using the system optimisation model OPERA the authors have analysed the technology sector and cost implications of the assumptions underlying these scenarios. While the roles of a number of key energy technology and emission mitigation options are strongly dependent on the scenario and cost assumptions the analysis yields several common elements that appear in both scenarios and that consistently appear under differing cost assumptions. For example one of the main options for the decarbonisation of the Dutch energy system is electrification of energy use in end-use sectors and for the production of renewable hydrogen with electrolysers. As a result the level of electricity generation in 2050 will be three to four times higher than present generation levels. Ultimately renewable energy – particularly from wind turbines and solar panels – is projected to account for the vast majority of electricity generation around 99% in 2050. Imbalances between supply and demand resulting from this variable renewable electricity production can be managed via flexibility options including demand response and energy storage. Hydrogen also becomes an important energy carrier notably for transportation and in industry. If import prices are lower than costs of domestic production from natural gas with CCS or through electrolysis from renewable electricity (2.4–2.7 €/kgH2) the use of hydrogen increases especially in the built environment.

Decarbonisation should be very much on the radar of new LNG projects currently taking FID commissioning around 2024-25 and planning to operate up to 2050. The LNG community needs to replace an `advocacy’ message – based on the generality of emissions from combustion of natural gas being lower than from other fossil fuels – with certified data on carbon and methane emissions from specific elements of the value chain for individual projects. As carbon reduction targets tighten over the coming decade LNG cargoes which do not have value chain emissions certified by accredited authorities or which fail to meet defined emission levels run the risk of progressively being deemed to have a lower commercial value and eventually being excluded from jurisdictions with the strictest standards. There will be no place in this process for confidentiality; nothing less than complete transparency of data and methodologies will be acceptable.<br/>In relation to affordability prospects for new projects look much better than they did three years ago. Cost estimates for most new projects suggest that they will be able to deliver profitably to most established and anticipated import markets at or below the wholesale prices prevailing in those markets over the past decade although affordability in south Asian countries may be challenging. But new projects need to factor in costs related to future decarbonisation requirements in both exporting and importing countries. To the extent that LNG suppliers can meet standards through relatively low-cost offsets – forest projects low-cost biogas and biomethane – this may not greatly impact their commercial viability. However any requirement to transform methane into hydrogen with CCS in either the exporting or importing country would substantially impact project economics and the affordability of LNG relative to other energy choices.

This Insight continues the OIES series considering the future of gas. The clear message from previous papers is that on the (increasingly certain) assumption that governments in major European gas markets remain committed to decarbonisation targets the existing natural gas industry is under threat.   It is therefore important to develop a decarbonisation narrative leading to a low- or zero-carbon gas implementation plan.



Previous papers have considered potential pathways for gas to decarbonise specifically considering biogas and biomethane and power-to-gas (electrolysis) . This paper goes on to consider the potential for production transport and use of hydrogen in the decarbonising energy system. Previous papers predominately focused on Europe which has been leading the way in decarbonisation. Hydrogen is now being considered more widely in various countries around the world so this paper reflects that wider geographical coverage.



Since the term ‘hydrogen economy’ was first used in 1970 there have been a number of ‘false dawns’ with bold claims for the speed of transition to hydrogen.  This Insight argues that this time for some applications at least there are grounds for optimism about a future role for decarbonised hydrogen but the lesson from history is that bold claims need to be examined carefully and treated with some caution. There are no easy or low-cost solutions to decarbonisation of the energy system and this is certainly the case for possible deployment of low-carbon hydrogen. A key challenge is to demonstrate the technical commercial economic and social acceptability of various possibilities at scale. Hydrogen will certainly play a role in decarbonisation of the energy system although the size of the role may be more limited than envisaged in some more optimistic projections.

Since the COP 21 meeting in Paris in December 2015 there has been a growing realisation that with the long-term objective that the energy system should be approaching carbon-neutrality by 2050 continuing to burn significant quantities of fossil-derived natural gas will not be sustainable. If existing natural gas infrastructure is to avoid becoming stranded assets plans to decarbonise the gas system need to be developed as a matter of urgency in the next three to five years given the typical life expectancy of such assets of 20 years or more. One of the options to decarbonise gas is “power-to-gas”: production of hydrogen or renewable methane via electrolysis using surplus renewable electricity. This Energy Insight reviews the status of power-to-gas and makes an assessment of potential future development pathways and the role which it could play in decarbonising the energy system.

New technological solutions are required to control the impact of the increasing presence of renewable energy sources connected to the electric grid that are characterized by unpredictable production (i.e. wind and solar energy). Energy storage is becoming essential to stabilize the grid when a mismatch between production and demand occurs. Among the available solutions Power to Hydrogen (P2H) is one of the most attractive options. However despite the potential many barriers currently hinder P2H market development. The literature reports general barriers and strategies to overcome them but a specific analysis is fundamental to identifying how these barriers concretely arise in national and regional frameworks since tailored solutions are needed to foster the development of P2H local market. The paper aims to identify and to analyze the existing barriers for P2H market uptake in Italy. The paper shows how several technical regulatory and economic issues are still unsolved resulting in a source of uncertainty for P2H investment. The paper also suggests possible approaches and solutions to address the Italian barriers and to support politics and decision-makers in the definition and implementation of the national hydrogen strategy.

A feasible path to limit planetary warming to 1.5°C requires certain countries and sectors to go below net zero and to do so well before the middle of the century according to new analysis from the authors of the Energy Transition Outlook. DNV’s pathway to net zero says North America and Europe must be carbon neutral by 2042 whereas Indian Subcontinent is set to be a net emitter by 2050 Net zero report says carbon capture storage and use is required as energy production will not be carbon neutral by 2050 Aim to halve emissions by 2030 is out of reach but massive early action is needed if we are to have any chance of reaching a 1.5°C future DNV’s new report “Pathway to Net Zero Emissions” describes a feasible way to limit global warming to 1.5°C Policy makers are set to meet in Glasgow for the COP 26 summit with an eye on achieving zero emissions by 2050. For this to happen North America and Europe must be carbon neutral by 2042 and then carbon negative thereafter according to DNV’s pathway to net zero. The pathway also finds that Greater China must reduce emissions by 98% from 2019 levels by 2050. There are regions that cannot realistically transition completely away from fossil fuels in the same timeframe such as the Indian Subcontinent which will reduce emissions by 64%. Pathway to Net Zero Emissions also lays out the pace at which different industry sectors need to decarbonize. The so-called hard-to-abate sectors will take longer to decarbonize and even if sectors like maritime (-90% CO2 emissions in 2050) and iron and steel production (-82%) scale up the introduction of greener technologies they will still be net emitters by 2050.

For many a large-scale hydrogen economy is essential to a a clean energy future with three quarters of the more than 1100 senior energy professionals we surveyed saying Paris Agreement targets will not be possible without it.

DNV’s research Rising to the challenge of a hydrogen economy explores the outlook for emerging hydrogen value chains from production to consumption. It combines the wider view from the energy industry with commentary from business leaders and experts. Our research finds that the challenge is not in the ambition but in changing the timeline: from hydrogen on the horizon to hydrogen in our homes businesses and transport systems.

We see that the energy industry is rising to this challenge. By 2025 almost half (44%) of energy companies globally involved in hydrogen expect it to account for more than a tenth of their revenue rising to 73% of companies by 2030 – up significantly from just 8% of companies today. The research identifies infrastructure and cost as two of the biggest hurdles while the right regulations are deemed the most powerful enabler followed by carbon pricing. Proving the safety case will also be key to scaling the hydrogen economy.

As nations around the world seek to reduce carbon dioxide emissions in order to mitigate climate change risks there has been a resurgence of interest in the use of hydrogen as a zero-emissions energy carrier. Hydrogen can be produced from diverse feedstocks via a range of low-emissions pathways and has broad potential in the process of decarbonization across the energy transport and industrial sectors.<br/>With an abundance of both renewable and fossil fuel energy resources a comparatively low national energy demand and excellent existing regional resource trading links Australia is well positioned to pursue industrial-scale hydrogen production for both domestic and export purposes. In this paper we present an overview of the progress at the government industry and research levels currently undertaken to enable a large-scale hydrogen industry for Australia.

With the restructuring of the power system household-level end users are becoming more prominent participants by integrating renewable energy sources and smart devices and becoming flexible prosumers. The use of microgrids is a way of aggregating local end users into a single entity and catering for the consumption needs of shareholders. Various microgrid architectures are the result of the local energy community following different decarbonisation strategies and are frequently not optimised in terms of size technology or other influential factors for energy systems. This paper discusses the operational and planning aspects of three different microgrid setups looking at them as individual market participants within a local electricity market. This kind of implementation enables mutual trade between microgrids without additional charges where they can provide flexibility and balance for one another. The developed models take into account multiple uncertainties arising from photovoltaic production day-ahead electricity prices and electricity load. A total number of nine case studies and sensitivity analyses are presented from daily operation to the annual planning perspective. The systematic study of different microgrid setups operational principles/goals and cooperation mechanisms provides a clear understanding of operational and planning benefits: the electrification strategy of decarbonising microgrids outperforms gas and hydrogen technologies by a significant margin. The value of coupling different types of multi-energy microgrids with the goal of joint market participation was not proven to be better on a yearly level compared to the operation of same technology-type microgrids. Additional analyses focus on introducing distribution and transmission fees to an MG cooperation model and allow us to come to the conclusion of there being a minor impact on the overall operation.

The unbridled use of fossil fuels is a serious problem that has become increasingly evident over the years. As such fuels contribute considerably to environmental pollution there is a need to find new sustainable sources of energy with low emissions of greenhouse gases. Climate change poses a substantial challenge for the scientific community. Thus the use of renewable energy through technologies that offer maximum efficiency with minimal pollution and carbon emissions has become a major goal. Technology related to the use of hydrogen as a fuel is one of the most promising solutions for future systems of clean energy. The aim of the present review was to provide an overview of elements related to the potential use of hydrogen as an alternative energy source considering its specific chemical and physical characteristics as well as prospects for an increase in the participation of hydrogen fuel in the world energy matrix.

The Republic of Djibouti has untapped potential in terms of renewable energy resources such as geothermal wind and solar energy. This study examines the economic feasibility of green hydrogen production by water electrolysis using wind and geothermal energy resources in the Asal–Ghoubbet Rift (AG Rift) Republic of Djibouti. It is the first study in Africa that compares the cost per kg of green hydrogen produced by wind and geothermal energy from a single site. The unit cost of electricity produced by the wind turbine (0.042 $/kWh) is more competitive than that of a dry steam geothermal plant (0.086 $/kWh). The cost of producing hydrogen with a suitable electrolyzer powered by wind energy ranges from $0.672/kg H2 to $1.063/kg H2 while that produced by the high-temperature electrolyzer (HTE) powered by geothermal energy ranges from $3.31/kg H2 to $4.78/kg H2 . Thus the AG Rift area can produce electricity and green hydrogen at low-cost using wind energy compared to geothermal energy. The amount of carbon dioxide (CO2 ) emissions reduced by using a “Yinhe GX113-2.5MW” wind turbine and a single flash geothermal power plant instead of fuel-oil generators is 2061.6 tons CO2/MW/year and 2184.8 tons CO2/MW/year respectively.

In recent years the development of energy prices in Germany has been frequently accompanied by criticism and warnings of socio-economic disruptions. Especially with respect to the electricity sector the debate on increasing energy bills was strongly correlated with the energy system transition. However whereas fossil fuels have rapidly increased in price recently renewable substitutes such as green hydrogen and synthetic fuels also enter the markets at comparatively high prices. On the other hand the present fossil fuel supply is still considered too low-priced by experts because societal greenhouse gas-induced environmental impact costs are not yet compensated. In this study we investigate the development of the price gap between conventional energy carriers and their renewable substitutes until 2050 as well as a suitable benchmark price incorporating the societal costs of specific energy carriers. The calculated benchmark prices for natural gas (6.3 ct kWh−1 ) petrol (9.9 ct kWh−1 ) and grey hydrogen from steam methane reformation (12 ct kWh−1 ) are nearly 300% above the actual prices for industry customers in 2020 but below the price peaks of early 2022. In addition the price gap between conventional fuels and green hydrogen will be completely closed before 2050 for all investigated energy carriers. Furthermore prognosed future price developments can be considered rather moderate compared to historic and especially to the recent price dynamics in real terms. A gradual implementation of green hydrogen and synthetic fuels next to increasing CO2 prices however may temporarily lead to further increasing expenses for energy but can achieve lower price levels comparable to those of 2020 in the long term.

A new report to the Secretary of State for Business Energy and Industrial Strategy from the Parliamentary Advisory Group on Carbon Capture and Storage (CCS) advises that that the UK  should kickstart CCS in order to save consumers billions a year from the cost of meeting climate change targets.

South Korea developed its hydrogen strategies to achieve carbon neutrality and dominate the hydrogen economy amidst and with the impetus of the coronavirus disease 2019 (COVID-19) pandemic. The government strives toward the goal via continuous investment in green hydrogen technologies as well as strategic collaborations. To facilitate the transition into the hydrogen economy this study presents a research and development (R&D) investment and collaboration framework as a national strategy. The framework offers abundant information to elucidate the technology R&D spectrum and regional dimensions of the strategy. Furthermore the proposed framework was applied to the Korean hydrogen economy comprising 955 nationally funded projects worth USD 565.7 million. The statuses and trends of the government’s investment in nationally funded research projects are illustrated with regard to the value chains of the hydrogen economies of 16 regions as well as nine technology clusters relating to the hydrogen economy thereby determining the research organizations that played crucial roles in each cluster of the 16 regions between 2015 and 2020. The results indicate that the research organizations in Daejeon acquired the highest government R&D funding in many hydrogen-economy-related research fields and that an R&D spectrum-based research/strategic collaboration is required to accomplish specialized complexes in the regions.

The UK’s first-ever Hydrogen Strategy drives forward the commitments laid out in the Prime Minister’s ambitious 10 Point Plan for a green industrial revolution by setting the foundation for how the UK government will work with industry to meet its ambition for 5GW of low carbon hydrogen production capacity by 2030 – the equivalent of replacing natural gas in powering around 3 million UK homes each year as well as powering transport and businesses particularly heavy industry.<br/>A booming UK-wide hydrogen economy could be worth £900 million and create over 9000 high-quality jobs by 2030 potentially rising to 100000 jobs and worth up to £13 billion by 2050. By 2030 hydrogen could play an important role in decarbonising polluting energy-intensive industries like chemicals oil refineries power and heavy transport like shipping HGV lorries and trains by helping these sectors move away from fossil fuels. Low-carbon hydrogen provides opportunities for UK companies and workers across our industrial heartlands.<br/>With government analysis suggesting that 20-35% of the UK’s energy consumption by 2050 could be hydrogen-based this new energy source could be critical to meet our targets of net zero emissions by 2050 and cutting emissions by 78% by 2035 – a view shared by the UK’s independent Climate Change Committee. In the UK a low-carbon hydrogen economy could deliver emissions savings equivalent to the carbon captured by 700 million trees by 2032 and is a key pillar of capitalising on cleaner energy sources as the UK moves away from fossil fuels.

The utilization of hydrogen energy is important for achieving a low-carbon society. Japan has set ambitious goals for hydrogen stations and fuel cell vehicles focusing on the introduction and dissemination of self-refuelling systems. This paper evaluates public trust in the fuel equipment and self-handling technology related to self-refuelling hydrogen stations and compares it with that for widespread gasoline stations. To this end the results of an online survey of 300 people with Japanese driver licenses are reported and analyzed. The results show that trust in the equipment and self-handling is more important for the user than trust in the fuel. In addition to introduce and disseminate new technology such as hydrogen stations users must be made aware of the risk of using the technology until it becomes as familiar as existing gasoline station technology.

The National Hydrogen Roadmap provides a blueprint for the development of a hydrogen industry in Australia.

Recently there has been a considerable amount of work undertaken (both globally and domestically) seeking to quantify the economic opportunities associated with hydrogen. The National Hydrogen Roadmap takes that analysis a step further by focusing on how those opportunities can be realised.

National Hydrogen Roadmap

The National Hydrogen Roadmap provides a blueprint for the development of a hydrogen industry in Australia.

The primary objective of the Roadmap is to provide a blueprint for the development of a hydrogen industry in Australia. With a number of activities already underway it is designed to help inform the next series of investment amongst various stakeholder groups (e.g. industry government and research) so that the industry can continue to scale in a coordinated manner.

Pathways to an economically sustainable industry

The low emissions hydrogen value chain now consists of a series of mature technologies. While there is considerable scope for further R&D this level of maturity has meant that the narrative has shifted from one of technology development to market activation.

Barriers to market activation stem from a lack of supporting infrastructure and/or the cost of hydrogen supply. However both barriers can be overcome via a series of strategic investments along the value chain from both the private and public sector.

The report shows that while government assistance is needed to kick-start the industry it can become economically sustainable thereafter. This is demonstrated by first assessing the target price of hydrogen needed for it be competitive with other energy carriers and feedstocks. Second the assessment considers the current state of the industry namely the cost and maturity of the underpinning technologies and infrastructure. It then identifies the material cost drivers and consequently the key priorities and areas for investment needed to make hydrogen competitive in each of the identified markets.

The opportunity for hydrogen to compete favourably on a cost basis in local applications such as transport and remote area power systems is within reach based on potential cost reductions to 2025. Further the development of a hydrogen export industry represents a significant opportunity for Australia and a potential 'game changer' for the local industry and the broader energy sector due to associated increases in scale."

Over the past three years there has been a rapid increase in discussions across the different levels of Australia's governments about the role that hydrogen might play in helping the world transition to a low carbon future. While those working in the energy industry are aware of the opportunities and challenges that lay ahead the general public is less engaged. However we know from the  introduction of previous technologies that public attitudes towards technologies including whether they view them to be safe can severely impact overall acceptance. Understanding how the public perceives hydrogen both for domestic and export use and the potential benefits it brings to Australia is critical for the industry to progress. In this paper we present the initial findings of a national survey of the Australian public conducted in March 2021 which builds on the results of a previous survey conducted in 2018. The 2021 respondents were drawn from all Australian states and territories (n=3020) and quotas were used to ensure adequate representation of age groups and gender. Overall the respondents have favorable views about using hydrogen for energy in Australia with caveats about production-related environmental impacts and issues such as safety. While there has been a slight increase in support for hydrogen as a possible solution for energy and environmental challenges since the 2018 survey the effect size is very small. This suggests that while hydrogen discussions have increased at a policy level little has been done to improve public understanding of hydrogen in communication strategies will be needed as the Australian hydrogen industry continues to develop and gain more widespread media attention.

Policy Connect Carbon Connect and sector and Parliamentary experts have collaborated to present options for the gas grid to play a useful role in the UK’s transition to a low carbon energy system through the widespread use of low carbon gas. The report calls on Government to support the transition to a more flexible gas grid that uses various forms of gas including low carbon gases such as hydrogen and biomethane.

Global climate change concerns have pushed international governmental actions to reduce greenhouse gas emissions by adopting cleaner technologies hoping to transition to a more sustainable society. The hydrogen economy is one potential long-term option for enabling deep decarbonization for the future energy landscape. Progress towards an operating hydrogen economy is discouragingly slow despite global efforts to accelerate it. There are major mismatches between the present situation surrounding the hydrogen economy and previous proposed milestones that are far from being reached. The overall aim of this study is to understand whether there has been significant real progress in the achievement of a hydrogen economy or whether the current interest is overly exaggerated (hype). This study uses bibliometric analysis and content analysis to historically map the hydrogen economy’s development from 1972 to 2020 by quantifying and analyzing three sets of interconnected data. Findings indicate that interest in the hydrogen economy has significantly progressed over the past five decades based on the growing numbers of academic publications media coverage and projects. However various endogenous and exogenous factors have influenced the development of the hydrogen economy and created hype at different points in time. The consolidated results explore the changing trends and how specific events or actors have influenced the development of the hydrogen economy with their agendas the emergence of hype cycles and the expectations of a future hydrogen economy.

Existing studies of financing efficiency concentrate on capital structure and a single external environment or internal management characteristic. Few of the studies include the internal and external financing environments at the same time for hydrogen energy industry financing efficiency. This paper used the data envelopment analysis (DEA) model and the Malmquist index to measure the financing efficiency of 70 hydrogen energy listed enterprises in China from 2014 to 2020 from both static and dynamic perspectives. Then a tobit model was constructed to explore the influence of external environment and internal factors on the financing efficiency. The contributions of this paper are studying the internal and external financing environments and integrating financing cost efficiency and capital allocation efficiency into the financing efficiency of hydrogen energy enterprises. The results show that firstly the financing efficiency of China’s hydrogen energy listed enterprises showed an upward trend during the years 2014–2020. Secondly China’s hydrogen energy enterprises mainly gather in the eastern coastal areas and their financing efficiency is more than that in western areas. Thirdly the regional economic development level enterprise scale financing structure capital utilization efficiency and profitability have significant effects on the financing efficiency. These results can promote the achievement of “carbon neutrality” in China.

Power to gas (PTG) refers to the technology of converting power into energy-storage gas which can absorb excess power when there is excess power and release energy-storage gas when needed. Based on the carbon dioxide (CO2 ) emission of Karamay City in Northwest China this study designed a process flow of the CO2 absorption process and the hydrogen and CO2 methanation process in PTG technology. The results show that the efficiency of the CO2 absorption process was 91.5% and the methanation efficiency was 77.5%. The heat recovery module was set during the process and the total heat recovered was 17.85 MW. The cost of producing synthetic natural gas (SNG) in the PTG factory was 1782 USD/ton. In terms of cost the cost of hydrogen production from electrolyzed water accounted for the largest proportion. In terms of product profit the sale of pure oxygen was the largest part of the profit. At present the carbon emission reduction index profit brought by SNG production accounted for a small proportion. In the future with technological progress industrial upgrading and the improvement in the carbon trading market PTG technology is expected to become one of the ways to achieve carbon-emission-reduction targets.

Hybrid renewable energy systems that combine heat and electricity generation is an achievable option for remote areas where grid is uneconomical to extend. In this study a renewable-based system was designed to satisfy the electrical and thermal demands of a remote household in an off-grid Greek island. A hybrid DC system consisted of a combination of photovoltaic modules wind turbine electrolyzer-hydrogen tank fuel cell and batteries were analysed using HOMER Pro software. Based on the optimal obtained system it is found that such a system can satisfy both electrical and thermal load demand throughout the year in a reliable manner.

In order to limit the effects of climate change the carbon dioxide emissions associated with the energy sector need to be reduced. Significant reductions can be achieved by using appropriate technologies and policies. In the context of recent discussions about climate change and energy transition this article critically reviews some technologies policies and frequently discussed solutions. The options for carbon emission reductions are grouped into (1) generation of secondary energy carriers (2) end-use energy sectors and (3) sector interdependencies. The challenges on the way to a decarbonized energy sector are identified with respect to environmental sustainability security of energy supply economic stability and social aspects. A global carbon tax is the most promising instrument to accelerate the process of decarbonization. Nevertheless this process will be very challenging for humanity due to high capital requirements the competition among energy sectors for decarbonization options inconsistent environmental policies and public acceptance of changes in energy use.

Green hydrogen will play a key role in building a climate-neutral energy-intensive industry as key technologies for defossilising the production of steel and basic chemicals depend on it. Thus policy-making needs to support the creation of a market for green hydrogen and its use in industry. However it is unclear how appropriate policies should be designed and a number of challenges need to be addressed. Based on an analysis of the ongoing German debate on hydrogen policies this paper analyses how policy-making for green hydrogen development may support industry defossilisation. For the assessment of policy instruments a simplified multi-criteria analysis (MCA) is used with an innovative approach that derives criteria from specific challenges. Four challenges and seven relevant policy instruments are identified. The results of the MCA reveal the potential of each of the selected instruments to address the challenges. The paper furthermore outlines how instruments might be combined in a policy package that supports industry defossilisation creates synergies and avoids trade-offs. The paper’s impact may reach beyond the German case as the challenges are not specific to the country. The results are relevant for policy-makers in other countries with energy-intensive industries aiming to set the course towards a hydrogen future.

This study aims to help the Department for Business Energy and Industrial Strategy (BEIS) determine whether the government should intervene to enable or require hydrogen-ready industrial boiler equipment. It will do this based on information from existing literature along with qualitative and quantitative information from stakeholder engagement. The study draws on evidence gathered through BEIS’ Call for Evidence (CfE) on hydrogen-ready industrial boilers. The assessment will advance the overall understanding of hydrogen-ready industrial boilers based on four outputs: definitions of hydrogen-readiness comparisons of the cost and resource requirement to install and convert hydrogen-ready industrial boiler equipment supply chain capacity for conversion to hydrogen and estimates of the UK industrial boiler population.

Sustainable hydrogen production is a priority for Morocco and it’s part of the country’s national energy strategy which is currently being developed. Many processes can be used for its production. However it’s necessary to select the appropriate one for Morocco’s case. In this study a multi-criteria analysis was followed to select the best clean and renewable catalytic process for hydrogen production on an industrial scale. Ten routes were evaluated using the AHP method coupled with the Fuzzy Vikor method for criteria weighting and ranking of alternatives respectively. The results showed that alkaline water electrolysis coupled with renewable energy sources is the most suitable for industrial production in Morocco. The processes that are not well ranked and require further study and development before deployment on an industrial scale are biophotolysis photo fermentation photolysis and thermolysis. The parametric sensitivity analysis performed validated the result obtained. Then the potential for hydrogen production using solar energy is investigated. It was found that Morocco can produce 1057.26 million tons of green hydrogen showing how attractive the selected catalytic process is. This study enables investors and decision-makers to make an informed decision about whether to develop a green hydrogen production industrial installation in Morocco.

This paper analyses which sources of low-carbon hydrogen for the Northwest European market are most competitive taking into account costs of local production conversion and transport. Production costs of electrolysis are strongly affected by local renewable electricity costs and capacity factors. Transport costs are the lowest by pipelines for distances under 10000 km with costs linearly increasing with distance. For larger distances transport as ammonia is more efficient with less relation to distance despite higher conversion costs. The most competitive low-carbon hydrogen supply to the Northwest European market appears to be local Steam Methane Reforming with Carbon Capture and Storage when international gas prices return back to historical levels. When gas prices however remain high then import from Morocco with electrolysis directly connected to offshore wind generation is found to be the most competitive source of low-carbon hydrogen. These conclusions are robust for various assumptions on costs and capacity factors.

In order to achieve carbon neutrality in a few decades the clean energy proportion in power mix of China will significantly rise to over 90%. A consensus has been reached recently that it will be of great significance to promote hydrogen energy that is produced by variable renewable energy power generation as a mainstay energy form in view of its potential value on achieving carbon neutrality. This is because hydrogen energy is capable of complementing the power system and realizing further electrification especially in the section that cannot be easily replaced by electric energy. Power system related planning model is commonly used for mid-term and long-term planning implemented through power installation and interconnection capacity expansion optimization. In consideration of the high importance of hydrogen and its close relationship with electricity an inclusive perspective which contains both kinds of the foresaid energy is required to deal with planning problems. In this study a joint model is established by coupling hydrogen energy model in the chronological operation power planning model to realize coordinated optimization on energy production transportation and storage. By taking the carbon neutrality scenario of China as an example the author applies this joint model to deploy a scheme research on power generation and hydrogen production inter-regional energy transportation capacity and hydrogen storage among various regions. Next by taking the technology progress and cost decrease prediction uncertainty into account the main technical– economic parameters are employed as variables to carry out sensitivity analysis research with a hope that the quantitative calculation and results discussion could provide suggestion and reference to energy-related companies policy-makers and institute researchers in formulating strategies on related energy development.
