Polymer electrolyte membrane (PEM) water electrolysis has demonstrated its potentialities in terms of cell efficiency (energy consumption ≈ 4.0-4.2 kW/Nm3 H2) and gas purity (> 99.99% H2). Current research activities are aimed at increasing operating pressure up to several hundred bars for direct storage of hydrogen in pressurized vessels. Compared to atmospheric pressure electrolysis high-pressure operation yields additional problems especially with regard to safety considerations. In particular the rate of gases (H2 and O2) cross-permeation across the membrane and their water solubility both increase with pressure. As a result gas purity is affected in both anodic and cathodic circuits and this can lead to the formation of explosive gas mixtures. To prevent such risks two different solutions reported in this communication have been investigated. First the chemical modification of the solid polymer electrolyte in order to reduce cross-permeation phenomena. Second the use of catalytic H2/O2 recombiners to maintain H2 levels in O2 and O2 levels in H2 at values compatible with safety requirements.

The paper presents HyResponse project i.e. a European Hydrogen Safety Training Platform that targets to train First responders to acquire professional knowledge and skills to contribute to FCH permitting process as approving authority. The threefold training program is described: educational training operational-level training on mock-up real scale transport and hydrogen stationary installations and innovative virtual training exercises reproducing entire accident scenarios. The paper highlights how the three pilot sessions for European First Responders in a face to face mode will be organized to get a feedback on the training program. The expected outputs are also presented i.e. the Emergency Response Guide and a public website including teaching material and online interactive virtual training.

The Programme Review Report ensures that the FCH JU programme is aligned with its strategy and objectives. This year the programme review was performed following a new procedure: it was carried out by the European Commission’s in-house science service the Joint Research Committee (JRC). The 2017 review pays particular attention to the added value effectiveness and efficiency of FCH JU activities. The review is structured around six panels under three pillars: transport energy and cross-cutting projects summarising the FCH JU Project Portfolio

This report shows that low-carbon hydrogen supply at scale is economically and environmentally feasible and will have significant societal benefits if the right localised approach and best-practices for production are used. The report also demonstrates that there is not one single hydrogen production pathway to achieve low lifecycle greenhouse gas (GHG) emissions but rather the need for a fact-based approach that leverages regional resources and includes a combination of different production pathways. This will achieve both emission and cost reductions ultimately helping to decarbonize the energy system and limit global warming.

In 2020 more than 15 countries launched major hydrogen plans and policies and industry players announced new projects of more than 35GW until 2030. As this hydrogen momentum accelerates it is increasingly clear that decision makers must put the focus on decarbonization to ensure hydrogen can fulfil its potential as a key solution in the global clean energy transition making a significant contribution to net zero emissions. To support this effort the two-part Hydrogen Council report provides new data based on an assessment of the GHG emissions generated through different hydrogen supply pathways and the lifecycle GHG emissions for different hydrogen applications (see report part 1 – A Life-cycle Assessment). In addition the report explores 3 hypothetical hydrogen supply scenarios to measure the feasibility and impact of deploying renewable and low-carbon hydrogen at scale (report part 2 – Potential Supply Scenarios).

The report outlines that there are many ways of producing hydrogen and although GHG emissions vary widely very high CO2 savings can be achieved across a broad range of different hydrogen production pathways and end-uses. For example while “green” hydrogen produced through water electrolysis with renewable power achieves the lowest emissions “blue” hydrogen produced from natural gas with high CO2 capture rate and storage can also achieve low emissions if best technologies are used and best practices are followed. Across eight illustrative pathways explored in the report analysis shows that if hydrogen is used significant GHG emission reductions can be made: as much as 60-90% or more compared to conventional fossil alternatives. The study also looked into the gross water demand of hydrogen supply pathways. Water electrolysis has a very low specific water demand of 9 kg per kg of hydrogen compared to cooling of thermal power plants (hundreds of kg/kg) or biomass cultivation (hundreds to thousands of kg/kg).

Furthermore low-carbon hydrogen supply at scale is fully achievable. Having investigated two hypothetical boundary scenarios (a “green-only” and a “blue-only” scenario) to assess the feasibility and impact of decarbonized hydrogen supply the report found that both scenarios are feasible: they are not limited by the world’s renewables potential or carbon sequestration (CCS) capacities and they do not exceed the speed at which industry can scale. In the Hydrogen Council’s “Scaling up” study a demand of 21800 TWh hydrogen has been identified for the year 2050. To achieve this a compound annual growth rate of 30-35% would be needed for electrolysers and CCS. This deployment rate is in line with the growth of the offshore wind and solar PV industry over the last decade.

Hydrogen Council data released in January 2020 showed that a wide range of hydrogen applications can become competitive by 2030 driven also by falling costs of renewable and low-carbon hydrogen[1]. The new study indicates that a combination of “green” and “blue” production pathways would lead to hydrogen cost reductions relative to either boundary scenario. By making use of the near-term cost advantage of “blue” while also scaling up “green” hydrogen as the most cost-efficient option in many regions in the medium and long-term the combined approach lowers average hydrogen costs between now and 2050 relative to either boundary scenario.

Part 1 – A Life-cycle Assessment

• The life-cycle assessment (LCA) analysis in this study addresses every aspect of the supply chain from primary energy extraction to end use. Eight primary-energy-to-hydrogen value chains have been selected for illustrative purposes.
• Across the hydrogen pathways and applications depicted very high to high GHG emission reduction can be demonstrated using green (solar wind) and blue hydrogen.
• In the LCA study renewables + electrolysis shows strongest GHG reduction of the different hydrogen supply pathways assessed in this study with a best-case blue hydrogen pathway also coming into the same order of magnitude.

Part 2 – Potential Supply Scenarios

• Currently the vast majority of hydrogen is produced by fossil pathways. To achieve a ten-fold build-out of hydrogen supply by 2050 as envisaged by the Hydrogen Council in its ‘Scaling Up’ report (2017) the existing use of hydrogen – and all its many potential new roles – need to be met by decarbonized sources.
• Three hypothetical supply scenarios with decarbonized hydrogen sources are considered in the study: 1) a “green-only” renewables-based world; 2) a “blue-only” world relying on carbon sequestration; and 3) a combined scenario that uses a region-specific combination of green and blue hydrogen based on the expected regional cost development of each source.
• The study finds that a decarbonized hydrogen supply is possible regardless of the production pathway: while both the green and blue boundary scenario would be highly ambitious regarding the required speed of scale-up they do not exceed the world’s resources on either renewable energy or carbon sequestration capabilities.
• A combination of production pathways would result in the least-cost global supply over the entire period of scale-up. It does so by making best use of the near-term cost advantage of “blue” in some regions while simultaneously achieving a scale-up in electrolysis.
• In reality the decarbonized supply scenario will combine a range of different renewable and low-carbon hydrogen production pathways that are optimally suited to local conditions political and societal preferences and regulations as well as industrial and cost developments for different technologies.

This paper addresses how a global climate target may influence iron and steel production technology deployment and scrap use. A global energy system model ETSAP-TIAM was used and a Scrap Availability Assessment Model (SAAM) was developed to analyse the relation between steel demand recycling and the availability of scrap and their implications for steel production technology choices. Steel production using recycled materials has a continuous growth and is likely to be a major route for steel production in the long run. However as the global average of in-use steel stock increases up to the current average stock of the industrialised economies global steel demand keeps growing and stagnates only after 2050. Due to high steel demand levels and scarcity of scrap more than 50% of the steel production in 2050 will still have to come from virgin materials. Hydrogen-based steel production could become a major technology option for production from virgin materials particularly in a scenario where Carbon Capture and Storage (CCS) is not available. Imposing a binding climate target will shift the crude steel price to approximately 500 USD per tonne in the year 2050 provided that CCS is available. However the increased prices are induced by CO₂ prices rather than inflated production costs. It is concluded that a global climate target is not likely to influence the use of scrap whereas it shall have an impact on the price of scrap. Finally the results indicate that energy efficiency improvements of current processes will only be sufficient to meet the climate target in combination with CCS. New innovative techniques with lower climate impact will be vital for mitigating climate change.

The main goal of the project is to enable the wide adoption of H2NG (hydrogen in natural gas) blends by closing knowledge gaps regarding technical impacts on residential and commercial gas appliances. The project consortium will identify and recommend appropriate codes and standards that should be adapted to answer the needs and develop a strategy for addressing the challenges for new and existing appliances.<br/>This deliverable on market segmentation is part of work package 2 and provides a quantitative segmentation of the gas appliance market in terms of appliance population numbers. It therefore prepares the project partners to perform the subsequent selection of the most representative product types to be tested in the laboratories of the THyGA partners.<br/>The classification is developed to categorise appliances installed in the field based on available statistics calculation methods and estimations. As a result appliance populations are provided for each technology segment that draw a representative picture of the installed end-use appliances within the European Union in 2020.

Globally the accelerating use of renewable energy sources enabled by increased efficiencies and reduced costs and driven by the need to mitigate the effects of climate change has significantly increased research in the areas of renewable energy production storage distribution and end-use. Central to this discussion is the use of hydrogen as a clean efficient energy vector for energy storage. This review by experts of Task 32 “Hydrogen-based Energy Storage” of the International Energy Agency Hydrogen TCP reports on the development over the last 6 years of hydrogen storage materials methods and techniques including electrochemical and thermal storage systems. An overview is given on the background to the various methods the current state of development and the future prospects. The following areas are covered; porous materials liquid hydrogen carriers complex hydrides intermetallic hydrides electro-chemical storage of energy thermal energy storage hydrogen energy systems and an outlook is presented for future prospects and research on hydrogen-based energy storage

This work is part of a project that aims to develop a micromechanics based damage law taking into account hydrogen assisted degradation. A 'vintage' API 5L X56N and a 'modern' API 5L X70M pipeline steel have been selected for this purpose. The paper focuses on an experimental calibration of ductile damage properties of the well known complete Gurson model for the two steels in absence of hydrogen. A basic microstructural characterization is provided showing a banded ferrite-pearlite microstructure for both steels. Charpy impact tests showed splits at the fracture surface for the X70 steel. Double-notched round bar tensile tests are performed aiming to provide the appropriate input for damage model calibration. The double-notched nature of the specimens allows to examine the material state at maximum load in the unfailed notch and the final material state in the failed notch. Different notch radii are used capturing a broad range of positive stress triaxialities. The notches are optically monitored for transverse necking in two perpendicular directions (transverse to rolling and through thickness) to reveal any anisotropy in plastic deformation and/or damage. It is explained how the occurrence of splits at the segregation zone and anisotropy complicate the calibration procedure. Calibration is done for each steel and acceptable results are obtained. However the occurrence of splits did not allow to evaluate the damage model for the highest levels of tested stress triaxiality.
