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: f Read More

This report assesses the potential of hydrogen (H2) propulsion to reduce aviation’s climate impact. To reduce climate impact the industry will have to introduce further levers such as radically new technology significantly scale sustainable aviation fuels (SAF) such as synthetic fuel (synfuel) temporarily rely on offsets in large quantities or rely on a combination thereof. H2 propulsion is one such technology and this report assesses its potential in aviatio Read More

Fuel cells and hydrogen are a viable solution for European regions and cities to reduce their emissions and realise their green energy transition says new FCH JU study.In 2017 the FCH JU launched an initiative to support regions and cities in this regard. Today 89 regions and cities participate representing about one quarter of Europe's population surface area and GDP. These regions are pursuing ambitious plans to deploy FCH technology in the coming years. F Read More

Multiscale characterization of the hydrogenation process of silicon solar cell contacts based on c-Si/SiOx/nc-SiCx(p) has been performed by combining dynamic secondary ion mass-spectrometry (D-SIMS) atom probe tomography (APT) and transmission electron microscopy (TEM). These contacts are formed by high-temperature firing which triggers the crystallization of SiCx followed by a hydrogenation process to passivate remaining interfacial defects Read More

Hydrogen (H2) is expected to be a key instrument to meet the European Union (EU) Green Deal main objective: i.e. climate neutrality by 2050. Renewable hydrogen deployment is expected to significantly reduce EU greenhouse gas (GHG) emissions by displacing carbon-intensive sources of energy. However concerns have been raised recently regarding the potential global warming impact caused by hydrogen emissions. Although hydrogen is neither in Read More

Hydrogen is indispensable to decarbonise European industry and reach the EU’s 2030 climate targets and 2050 climate neutrality. It is one of the key technologies of Europe’s Net Zero Industry Act. By scaling up its production we will reduce the use of fossil fuels in European industries and serve the needs of hard-to-electrify sectors.

The modelling underpinning the scenarios for the EU long-term strategy did not include hydrogen trade. The assumption was that each Member State (MS) supplies its own needs for hydrogen and synthetic fuels. The goal of this study is to develop a model to undertake optimal geolocation of hydrogen production between MS including the possibility to trade hydrogen and therefore use the RES potential more optimally and decrease energy system costs at E Read More

Renewable and low carbon hydrogen is both an energy carrier able to produce other fuels and downstream products such as the e-fuels or e-ammonia and a decarbonised gas produced through renewable electricity. It has the potential to decarbonise hard to abate sectors which are difficult to directly electrify and play a crucial role in achieving net zero emissions target in 2050. The European Commission has recently outlined the policy context and necessar Read More

The Green Deal Industrial Plan aims to boost the competitiveness of Europe’s net-zero industry and to accelerate the transition to climate neutrality. The Plan is based on four pillars: (1) a predictable and simplified regulatory environment; (2) faster access to funding; (3) developing skills for net-zero industry; and (4) open trade for resilient supply chains.

The European Commission published its hydrogen strategy for a climate-neutral Europe on the 8th July 2020. This strategy brings different strands of policy action together covering the entire value chain as well as the industrial market and infrastructure angles together with the research and innovation perspective and the international dimension in order to create an enabling environment to scale up hydrogen supply and demand for a climate-ne Read More

This report analyses five case study reports in-depth across five EU countries as part of a broader analytical and critical exercise. This analytical work seeks to contribute to the development of new models for regional and local authorities aiming to boost support for Green Transition of their economies through smarter innovation policies using the smart specialisation (S3) approach. The work covered five regions from across the European Union represen Read More

The report provides a detailed examination of the biofuel sector and advanced biofuel sector within the European Union (EU) focusing on its economic environmental and technological dimensions. The report is an update of the CETO 2023 report. The EU is highlighted as the central point of view with specific references to EU Member States showcasing their roles in the sector. The report is essential for understanding the multifaceted role of advanced Read More

The report addresses the environmental challenges faced by European sea ports and aims to provide guidance to smaller ports for improving their environmental performance while achieving sustainability goals through experiences gained by implementing noteworthy green initiatives in practice. Larger ports possess significant advantages in terms of financial resources risk tolerance and organisational capacity. They often have the means to inve Read More

This report is an output of the Clean Energy Technology Observatory (CETO) and is an update of the “Water electrolysis and hydrogen in the European Union” 2023 CETO report. CETO’s objective is to provide an evidencebased analysis feeding the policy making process and hence increasing the effectiveness of R&I policies for clean energy technologies and solutions. It monitors EU research and innovation activities on clean energy technologies needed for th Read More

This report delves into the European renewable hydrogen supply chain to offer recommendations for Europe to become a leader in the hydrogen economy.

Seawater electrolysis is a promising approach for sustainable hydrogen production that could alleviate the ever-growing demand for freshwater resources. This literature review synthesizes current research on direct seawater electrolysis drawing attention to advances in electrode materials catalyst efficiency and system design. Furthermore an overview of indirect seawater electrolysis is given as a benchmark. Key challenges including electrode corrosi Read More
