Applications & Pathways

Minimising tailpipe emissions and the decarbonisation of transport in a cost effective way remains a major objective for policymakers and vehicle manufacturers. Current trends are rapidly evolving but appear to be moving towards solutions in which vehicles which are increasingly electrified. As a result we will see a greater linkage between the wider energy system and the transportation sector resulting in a more complex and mutual dependency. At the same time major investments into technological innovation across both sectors are yielding rapid advancements into on-board energy storage and more compact/lightweight on-board electricity generators. In the absence of sufficient technical data on such technology holistic evaluations of the future transportation sector and its energy sources have not considered the impact of a new generation of innovation in propulsion technologies. In this paper the potential impact of a number of novel powertrain technologies are evaluated and presented. The analysis considers heavy duty vehicles with conventional reciprocating engines powered by diesel and hydrogen hybrid and battery electric vehicles and vehicles powered by hydrogen fuel cells and freepiston engine generators (FPEGs). The benefits are compared for each technology to meet the expectations of representative medium and heavy-duty vehicle drivers. Analysis is presented in terms of vehicle type vehicle duty cycle fuel economy greenhouse gas (GHG) emissions impact on the vehicle etc.. The work shows that the underpinning energy vector and its primary energy source are the most significant factor for reducing primary energy consumption and net CO₂ emissions. Indeed while an HGV with a BEV powertrain offers no direct tailpipe emissions it produces significantly worse lifecycle CO2 emissions than a conventional diesel powertrain. Even with a de-carbonised electricity system (100 g CO2/kWh) CO₂ emissions are similar to a conventional Diesel fuelled HGV. For the HGV sector range is key to operator acceptability of new powertrain technologies. This analysis has shown that cumulative benefits of improved electrical powertrains on-board storage efficiency improvements and vehicle design in 2025 and 2035 mean that hydrogen and electric fuelled vehicles can be competitive on gravimetric and volumetric density. Overall the work demonstrates that presently there is no common powertrain solution appropriate for all vehicle types but how subtle improvements at a vehicle component level can have significant impact on the design choices for the wider energy system.

The synthesis of low-cost and highly active electrodes for both oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) is very important for water splitting. In this work the novel amorphous iron-nickel phosphide (FeP-Ni) nanocone arrays as efficient bifunctional electrodes for overall water splitting have been in-situ assembled on conductive three-dimensional (3D) Ni foam via a facile and mild liquid deposition process. It is found that the FeP-Ni electrode demonstrates highly efficient electrocatalytic performance toward overall water splitting. In 1 M KOH electrolyte the optimal FeP-Ni electrode drives a current density of 10 mA/cm2 at an overpotential of 218 mV for the OER and 120 mV for the HER and can attain such current density for 25 h without performance regression. Moreover a two-electrode electrolyzer comprising the FeP-Ni electrodes can afford 10 mA/cm2 electrolysis current at a low cell voltage of 1.62 V and maintain long-term stability as well as superior to that of the coupled RuO2/NF‖Pt/C/NF cell. Detailed characterizations confirm that the excellent electrocatalytic performances for water splitting are attributed to the unique 3D morphology of nanocone arrays which could expose more surface active sites facilitate electrolyte diffusion benefit charge transfer and also favourable bubble detachment behaviour. Our work presents a facile and cost-effective pathway to design and develop active self-supported electrodes with novel 3D morphology for water electrolysis.

Fuel cells and hydrogen (FCH) could bring significant environmental benefits across the energy system if deployed widely: low carbon and highly efficient energy conversions with zero air quality emissions. The socio-economic benefits to Europe could also be substantial through employment in development manufacturing installation and service sectors and through technology export. Major corporations are stressing the economic and environmental value of FCH technologies and the importance of including them in both transport and stationary energy systems globally while national governments and independent agencies are supporting their role in the energy systems transition.

Recognising the potential economic and industrial benefits from a strong FCH supply chain in Europe and the opportunities for initiatives to support new energy supply chains the FCH 2 JU commissioned a study to evaluate for the first time the value added that the fuel cell and hydrogen sector can bring to Europe by 2030.

The outputs of the study are divided into three reports:

• A ‘Summary’ report that provides a synthetic overview of the study conclusions;
• a ‘Findings’ report that presents the approach and findings of the study;
• and an ‘Evidence’ report  that provides the detailed background information and analysis that supports the findings and recommendations.

Multiple indicators suggest that the FCH sector is starting to grow and poised to grow fast. In fact this growth must be relatively rapid to create both the size of industry and the mature supply chains required for it to be self-sustaining. The supply chain is currently global and likely to remain so and Europe occupies a strong position within it. The study has concluded and provided evidences showing that the FCH sector offers Europe a chance to benefit economically and environmentally from an emerging industry and strengthen its position in clean technologies generally.

The Value Chain study complements the Hydrogen Roadmap for Europe recently published by the FCH 2 JU. This lays out a pathway for the large-scale deployment of hydrogen and fuel cells to 2050 in order to achieve a 2-degree climate scenario. This study also quantified socio-economic and environmental benefits but with important differences in scope between the two studies. The Hydrogen Roadmap for Europe looked at the wider picture quantifying the scale of FCH roll-out needed to meet the 2-degree scenario objectives. It assessed the socio-economic impacts of a sector of that scale looking top-down at the entire FCH value chain. The Value Chain study presented here is a narrower and more detailed bottom-up assessment of the value-added in manufacturing activities and the immediate ecosystem of suppliers that this is likely to create.

The UK is investigating supplying hydrogen to homes and businesses instead of natural gas by “repurposing” the gas network. It presents a major engineering challenge which has never been done anywhere else in the world.

In a new report titled ‘Transitioning to hydrogen’ experts from a cross-professional engineering institution (PEI) working group including the IET have assessed the engineering risks and uncertainties and concluded there is no reason why repurposing the gas network to hydrogen cannot be achieved. But there are several engineering risks and uncertainties which need to be addressed.

The U.S. transportation sector accounts for 37% of total energy consumption. Automobiles are a primary application of polymer electrolyte membrane (PEM) fuel cells which operate under low temperature and high efficiency to reduce fossil fuel consumption and CO2 emissions. Using hydrogen fuel PEM fuel cells can reach a practical efficiency as high as 65% with water as the only byproduct. Almost all the major automakers are involved in fuel cell electric vehicle (FCEV) development. Toyota and Hyundai introduced FCEVs (the Mirai and NEXO respectively) to consumers in recent years with a driving range between 312 and 402 miles and cold-start capacity from -30 °C. About 50 fuel cell electric buses (FCEB) are operating in California and most of them have achieved the durability target i.e. 25000 h in real-world driving conditions. As of September 2020 over 8573 FCEVs have been sold or leased in the U.S. More than 3521 FCEVs and 22 FCEBs have been sold or leased in Japan as of September 2019. An extensive hydrogen station network is required for the successful deployment of FCEVs and FCEBs. The U.S. currently has over 44 hydrogen fuelling stations (HFSs) nearly all located in California. Europe has over 139 HFSs with ~1500 more stations planned by 2025. This review has three primary objectives: 1) to present the current status of FCEV/FCEB commercialization and HFS development; 2) to describe the PEM fuel cell research/development in automobile applications and the significance of HFS networks; and 3) to outline major challenges and opportunities.

Conventional technologies are largely powered by fossil fuel exploitation and have ultimately led to extensive environmental concerns. Hydrogen is an excellent carbon-free energy carrier but its storage and long-distance transportation remain big challenges. Ammonia however is a promising indirect hydrogen storage medium that has well-established storage and transportation links to make it an accessible fuel source. Moreover the notion of ‘green ammonia’ synthesised from renewable energy sources is an emerging topic that may open significant markets and provide a pathway to decarbonise a variety of applications reliant on fossil fuels. Herein a comparative study based on the chosen design working principles advantages and disadvantages of direct ammonia fuel cells is summarised. This work aims to review the most recent advances in ammonia fuel cells and demonstrates how close this technology type is to integration with future applications. At present several challenges such as material selection NO_x formation CO₂ tolerance limited power densities and long term stability must still be overcome and are also addressed within the contents of this review.

This report is the public version of the deliverable B.3.7 'Life cycle assessment of Hydrogen and Fuel Cell Technologies - Inventory of work performed by projects funded under FCH JU'; it provides an overview of the progress achieved so far and a comprehensive analysis on Life Cycle Assessment (LCA) for various hydrogen technologies and processes. The review considers 73 Fuel Cells and Hydrogen 2 Joint Undertaking (FCH 2 JU) founded projects: for some of those the LCA study was requested in the call topic while other projects decided to perform the LCA study on a voluntary basis. The LCAs have been assessed regarding the adherence to guideline recommendations (e.g. reported properties system boundary definitions goal and scope definitions) methodology and overall quality of the work. Methodology is a critical issue for the comparability of results as this is only possible if all LCAs follow the same guidelines; in addition LCAs were often only partially fulfilling the selected guideline requirements. It is recommended that future FCH 2 JU call topics asking for environmental analysis to be performed are setting out some minimum requirements such as the guidelines to be used and the impacts to be assessed. Based on the outcome of this analysis a harmonisation effort in the approach to LCA for the FCH JU founded projects is proposed; in particular a Life Cycle Inventory (LCI) database useful for the projects is required togheter with the identification of a reference cases to be used as benchmark for future LCAs.

A major transformation and redesign of the global energy system is required towards decarbonisation and to achieve the Paris Agreement targets. This Grand Transition is a complex pressing issue where global joint efforts and system solutions are essential; with hydrogen being one of them.<br/>Hydrogen has the potential to be a powerful effective accelerator towards a low-carbon energy system capable of addressing multiple energy challenges: from facilitating the massive integration of renewables and decarbonisation of energy production to energy transportation in a zero-carbon energy economy to electrification of end uses.

The development of new infrastructure is often a consideration in the introduction of new innovations. Currently there is some confusion around how to develop a hydrogen infrastructure to support the introduction of FCVs. Lessons can be learned from similar technology introduction in the past and therefore this paper investigates how mobile phone infrastructure was developed allowing the mass-market penetration of mobile phones. Based on this successful infrastructural development suggestions can be made on the development of a hydrogen infrastructure. It is suggested that a hydrogen infrastructure needs to be pre-developed 3–5 years before the market introduction of FCVs can successfully occur. A lack of infrastructural pre-development will cause to the market introduction of FCVs to fail.

Improving energy system modelling capabilities can directly affect the quality of applied studies. However some modelling trade-offs are necessary as the computational capacity and data availability are constrained. In this paper we demonstrate modelling trade-offs resulting from the modification in the resolution of four modelling capabilities namely transitional scope European electricity interconnection hourly demand-side flexibility description and infrastructure representation. We measure the cost of increasing resolution in each capability in terms of computational time and several energy system modelling indicators notably system costs emission prices and electricity import and export levels. The analyses are performed in a national-level integrated energy system model with a linear programming approach that includes the hourly electricity dispatch with European nodes. We determined that reducing the transitional scope from seven to two periods can reduce the computational time by 75% while underestimating the objective function by only 4.6%. Modelers can assume a single European Union node that dispatches electricity at an aggregated level which underestimates the objective function by 1% while halving the computational time. Furthermore the absence of shedding and storage flexibility options can increase the curtailed electricity by 25% and 8% respectively. Although neglecting flexibility options can drastically decrease the computational time it can increase the sub-optimality by 31%. We conclude that an increased resolution in modelling flexibility options can significantly improve the results. While reducing the computational time by half the lack of electricity and gas infrastructure representation can underestimate the objective function by 4% and 6% respectively.

Steelmaking is responsible for around 7% of the global emissions of carbon dioxide and new steelmaking processes are necessary to reach international climate targets. As a response to this steelmaking processes based on the direct reduction of iron ore by hydrogen produced via water electrolysis powered by renewable electricity have been suggested. Here we present a novel variant of hydrogen-based steelmaking incorporating methanol as a hydrogen and carbon carrier together with high-temperature co-electrolysis of water and carbon dioxide and biomass oxy-fuel combustion. The energy and mass balances of the process are analyzed. It is found that this methanol-based direct reduction process may potentially offer a number of process-related advantages over a process based on pure hydrogen featuring several process integration options. Notably the electricity and total energy use of the steelmaking process could be reduced by up to 25% and 8% compared to a reference pure hydrogen process respectively. The amount of high-temperature (> 200 °C) heat that must be supplied to the process could also be reduced by up to approximately 34% although the demand for medium-temperature heat is substantially increased. Furthermore the suggested process could allow for the production of high-quality direct reduced iron with appropriate carburization to alleviate downstream processing in an electric arc furnace which is not the case for a process based on pure hydrogen.

Ammonia borane (AB) can be catalytically hydrolyzed to provide hydrogen at room temperature due to its high potentaial for hydrogen storage. Non-precious metal heterogeneous catalysts have broad application in the field of energy catalysis. In this article catalysts precursor is obtained from Co-Ti-resorcinol-formaldehyde resin by sol–gel method. Co/TiO2@N-C (CTC) catalyst is prepared by calcining the precursor under high temperature conditions in nitrogen atmosphere. Co-CoOx/TiO2@N-C (COTC) is generated by the controllable oxidation reaction of CTC. The catalyst can effectively promote the release of hydrogen during the hydrolytic dehydrogenation of AB. High hydrogen generation at a specific rate of 5905 mL min−1 gCo−1 is achieved at room temperature. The catalyst retains its 85% initial catalytic activity even for its fifth time use in AB hydrolysis. The synergistic effect among Co Co3O4 and TiO2 promotes the rate limiting step with dissociation and activation of water molecules by reducing its activation energy. The applied method in this study promotes the development of non-precious metals in catalysis for utilization in clean energy sources.

The production of hydrogen through water electrolysis is a promising pathway to decarbonize the energy sector. This paper presents a techno-economic model of electrolysis plants based on multiple states of operation: production hot standby and idle. The model enables the calculation of the optimal hourly dispatch of electrolyzers to produce hydrogen for different end uses. This model has been tested with real data from an existing installation and compared with a simpler electrolyzer model that is based on two states. The results indicate that an operational strategy that considers the multi-state model leads to a decrease in final hydrogen production costs. These reduced costs will benefit businesses especially while electrolysis plants grow in size to accommodate further increases in demand.

This paper presents a simulation tool for marine hybrid power-plants equipped with polymer exchange membrane fuel cells and batteries. The virtual model through the combination of operational data and dynamically modelled subsystems can simulate power-plants of different sizes and configurations in order to analyze the response of different energy management strategies. The model aims to replicate the realistic behavior of the components included in the vessel's grid to asses if the hardware selected by the user is capable of delivering the power set-point requested by the energy management system. The model can then be used to optimize key factors such as hydrogen consumption. The case study presented in the paper demonstrates how the model can be used for the evaluation of a retrofitting operation replacing a diesel electric power-plant with fuel cells and batteries. The vessel taken into consideration is a domestic ferry operating car and passenger transport in Denmark. The vessel is outfitted with a diesel electric plant and an alternative hybrid power-plant is proposed. The hybrid configuration is tested using the model in a discrete time-domain.

The maritime shipping sector is a major contributor to CO₂ emissions and this figure is expected to rise in coming decades. With the intent of reducing emissions from this sector this research proposes the utilization of the jet stream to transport a combination of cargo and hydrogen using airships or balloons at altitudes of 10–20 km. The jet streams flow in the mid-latitudes predominantly in a west–east direction reaching an average wind speed of 165 km/h. Using this combination of high wind speeds and reliable direction hydrogen-filled airships or balloons could carry hydrogen with a lower fuel requirement and shorter travel time compared to conventional shipping. Jet streams at different altitudes in the atmosphere were used to identify the most appropriate circular routes for global airship travel. Round-the-world trips would take 16 days in the Northern Hemisphere and 14 in the Southern Hemisphere. Hydrogen transport via the jet stream due to its lower energy consumption and shorter cargo delivery time access to cities far from the coast could be a competitive alternative to maritime shipping and liquefied hydrogen tankers in the development of a sustainable future hydrogen economy.

Increased use of renewable energy combined with intensified electrification could prove decisive for the world to meet key climate goals by 2050. This study from the International Renewable Energy Agency (IRENA) highlights immediately deployable cost-effective options for countries to fulfil climate commitments and limit the rise of global temperatures. The envisaged energy transformation would also reduce net costs and bring significant socio-economic benefits such as increased economic growth job creation and overall welfare gains.<br/>The report – the second under the Global Energy Transformation banner – expands IRENA’s comprehensive roadmap which examines technology pathways and policy implications to ensure a sustainable energy future. Ramping up electricity to over half of the global energy mix (up from one-fifth currently) in combination with renewables would reduce the use of fossil fuels responsible for most greenhouse-gas emissions.

Fuel cell technologies have several applications in stationary power production such as units for primary power generation grid stabilization systems adopted to generate backup power and combined-heat-and-power configurations (CHP). The main sectors where stationary fuel cells have been employed are (a) micro-CHP (b) large stationary applications (c) UPS and IPS. The fuel cell size for stationary applications is strongly related to the power needed from the load. Since this sector ranges from simple backup systems to large facilities the stationary fuel cell market includes few kWs and less (micro-generation) to larger sizes of MWs. The design parameters for the stationary fuel cell system differ for fuel cell technology (PEM AFC PAFC MCFC and SOFC) as well as the fuel type and supply. This paper aims to present a comprehensive review of two main trends of research on fuel-cell-based poly-generation systems: tracking the market trends and performance analysis. In deeper detail the present review will list a potential breakdown of the current costs of PEM/SOFC production for building applications over a range of production scales and at representative specifications as well as broken down by component/material. Inherent to the technical performance a concise estimation of FC system durability efficiency production maintenance and capital cost will be presented.

Due to the low density of hydrogen gas under ambient temperature and atmospheric pressure conditions the high-pressure gaseous hydrogen storage method is widely employed. With high-pressure characteristics of hydrogen storage rigorous safety precautions are required such as filling of compressed gas in a hydrogen tank to achieve reliable operational solutions. Especially for the large-sized tanks (above 150 L) safety operation of hydrogen storage should be considered. In the present study the compressed hydrogen gas behavior in a large hydrogen tank of 175 L is investigated for its filling. To validate the numerical approach used in this study numerical models for the adaptation of the gas and turbulence models are examined. Numerical parametric studies on hydrogen filling for the large hydrogen tank of 175 L are conducted to estimate the hydrogen gas behavior in the hydrogen tank under various conditions of state of charge of pressure and ambient temperature. From the parametric studies the relationship between the initial SOC pressure condition and the maximum temperature rise of hydrogen gas was shown. That is the maximum temperature rise increases as the ambient temperature decreases and the rise increases as the SOC decreases.

There is a growing conversation around the role that hydrogen can play in the future of the UK and how to best harness its potential to secure jobs show climate leadership promote industrial competitiveness and drive innovation. The Government’s ‘Ten Point Plan for a Green Industrial Revolution’ included hydrogen as one of its ten actions targeting 5GW of ‘low carbon’ hydrogen production by 2030. Britain is thus joining the EU US Japan Germany and a host of other countries seeking to be part of the hydrogen economy of the future.<br/><br/>A focus on clean green hydrogen within targeted sectors and hubs can support multiple Government goals – including demonstrating climate leadership reducing regional inequalities through the ‘levelling up’ agenda and ensuring a green and cost-effective recovery from the coronavirus pandemic which prioritises jobs and skills. A strategic hydrogen vision must be honest and recognise where green hydrogen does not present the optimal pathway for decarbonisation – for instance where alternative solutions are already readily available for roll-out are more efficient and cost-effective. A clear example is hydrogen use for heating where it is estimated to require around 30 times more offshore wind farm capacity than currently available to produce enough green hydrogen to replace all gas boilers as well as adding costs for consumers.<br/><br/>This paper considers the offer of hydrogen for key Government priorities – including an inclusive and resilient economic recovery from the pandemic demonstrating climate leadership and delivering for all of society across the UK. It assesses existing evidence and considers the risks and opportunities and how they might inform a strategic vision for the UK. Ahead of the forthcoming Hydrogen Strategy it sets expectations for Government and outlines key recommendations.

Long-haul heavy-duty vehicles including trucks and coaches contribute to a substantial portion of the modern-day European carbon footprint and pose a major challenge in emissions reduction due to their energy-intensive usage. Depending on the hydrogen fuel source the use of fuel cell electric vehicles (FCEV) for long-haul applications has shown significant potential in reducing road freight CO2 emissions until the possible maturity of future long-distance battery-electric mobility. Fuel cell heavy-duty (HD) propulsion presents some specific characteristics advantages and operating constraints along with the notable possibility of gains in powertrain efficiency and usability through improved system design and intelligent onboard energy and thermal management. This paper provides an overview of the FCEV powertrain topology suited for long-haul HD applications their operating limitations cooling requirements waste heat recovery techniques state-of-the-art in powertrain control energy and thermal management strategies and over-the-air route data based predictive powertrain management including V2X connectivity. A case study simulation analysis of an HD 40-tonne FCEV truck is also presented focusing on the comparison of powertrain losses and energy expenditures in different subsystems while running on VECTO Regional delivery and Long-haul cycles. The importance of hydrogen fuel production pathways onboard storage approaches refuelling and safety standards and fleet management is also discussed. Through a comprehensive review of the H2 fuel cell powertrain technology intelligent energy management thermal management requirements and strategies and challenges in hydrogen production storage and refuelling this article aims at helping stakeholders in the promotion and integration of H2 FCEV technology towards road freight decarbonisation.

This study investigates and controls the optimal operating oxygen excess ratio (OER) for PEMFC which effectively prevents oxygen starvation and improves the hydrogen economy of proton exchange membrane fuel cells (PEMFC). Firstly the PEMFC output characteristic model and the five-order nonlinear air supply system model are established. Moreover an adaptive algebraic observer was developed to observe the partial pressure of gas in PEMFC and further reconstruct OER. Secondly to achieve the minimum hydrogen consumption under the required power the reference OER is determined by analyzing the PEMFC system output power with its minimum current. Finally the super-twisting algorithm is adopted to track reference OER. Simulation results show that the average absolute observation errors of oxygen nitrogen and cathode pressures under the Highway Fuel Economy Test are 1351.1 Pa (5.1%) 1724.2 Pa (0.9%) and 409.9 Pa (1.6%) respectively. The OER adjust average absolute error is 0.03. Compared with the commonly used fixed OER (e.g. OER of 1.5 and 2.3) the optimal OER strategy can reduce the hydrogen consumption of the PEMFC system by 5.2% and 1.8% respectively. Besides a DSP hardware in loop test is conducted to show the real-time performance of the proposed optimal method.

The iron and steel industry is one of the world’s largest industrial emitters of greenhouse gases. One promising option for decarbonising the industry is hydrogen direct reduction of iron (H-DR) with electric arc furnace (EAF) steelmaking powered by zero carbon electricity. However to date little attention has been given to the energy system requirements of adopting such a highly energy-intensive process. This study integrates a newly developed long-term energy system planning tool with a thermodynamic process model of H-DR/EAF steelmaking developed by Vogl et al. (2018) to assess the optimal combination of generation and storage technologies needed to provide a reliable supply of electricity and hydrogen. The modelling tools can be applied to any country or region and their use is demonstrated here by application to the UK iron and steel industry as a case study. It is found that the optimal energy system comprises 1.3 GW of electrolysers 3 GW of wind power 2.5 GW of solar 60 MW of combined cycle gas with carbon capture 600 GWh/600 MW of hydrogen storage and 30 GWh/130 MW of compressed air energy storage. The hydrogen storage requirements of the industry can be significantly reduced by maintaining some dispatchable generation for example from 600 GWh with no restriction on dispatchable generation to 140 GWh if 20% of electricity demand is met using dispatchable generation. The marginal abatement costs of a switch to hydrogen-based steelmaking are projected to be less than carbon price forecasts within 5–10 years.

Electrifying energy-intensive processes is currently intensively explored to cut greenhouse gas (GHG) emissions through renewable electricity. Electrification is particularly challenging if fossil resources are not only used for energy supply but also as feedstock. Copper production is such an energy-intensive process consuming large quantities of fossil fuels both as reducing agent and as energy supply.

Here we explore the techno-economic potential of Power-to-Hydrogen to decarbonize copper production. To determine the minimal cost of an on-site retrofit with Power-to-Hydrogen technology we formulate and solve a mixed-integer linear program for the integrated system. Under current techno-economic parameters for Germany the resulting direct CO₂ abatement cost is 201 EUR/t CO₂-eq for Power-to-Hydrogen in copper production. On-site utilization of the electrolysis by-product oxygen has a substantial economic benefit. While the abatement cost vastly exceeds current European emission certificate prices a sensitivity analysis shows that projected future developments in Power-to-Hydrogen technologies can greatly reduce the direct CO₂ abatement cost to 54 EUR/t CO₂-eq. An analysis of the total GHG emissions shows that decarbonization through Power-to-Hydrogen reduces the global GHG emissions only if the emission factor of the electricity supply lies below 160 g CO2-eq/kWhel.

The results suggest that decarbonization of copper production by Power-to-Hydrogen could become economically and environmentally beneficial over the next decades due to cheaper and more efficient Power-to-Hydrogen technology rising GHG emission certificate prices and further decarbonization of the electricity supply.
