Each one links to its EU funding record and the partners it works with: a starting list for building a consortium.
Sustainability of Fuel Cells and Hydrogen (FCH) products is a key requirement in the path towards a hydrogen economy. In this regard, measuring the sustainability of FCH systems from a life cycle perspective has become a crucial need. To that end, guidelines for life cycle sustainability assessment (LCSA) of FCH systems have already been developed and applied within the scope of the JU-funded project SH2E[1], as well as ecodesign guidelines based on life cycle sustainability within the JU-funded projects eGHOST[2] and GUESS-WHy[3]. Moreover, when considering only the environmental dimension, the first Product Environmental Footprint Category Rules (PEFCRs) specific to FCH products are being proposed and applied within the JU-funded project HyPEF[4]. This expands the spectrum of methodological initiatives on environmental life cycle assessment (LCA) guidelines for FCH systems under the JU-funded projects SH2E1 and FC-HyGuide[5]. Hence, beyond regular LCA implementation in JU-funded projects, previous LCA and FCH-specific efforts have focused on providing guidance for calculating products’ life cycle impacts with increased reproducibility, relevance, and consistency. However, a successful and widespread adoption of these FCH-specific approaches is mainly conditioned by the limited availability of high-quality datasets (i.e. inventories) across the value chain of hydrogen-related systems. According to the identified gap (lack of robust datasets relevant to FCH systems), this topic addresses the development and application of a number of high-quality, open-access (e.g. CC BY license) and freely accessible datasets, also referred to as Life Cycle Inventories (LCIs), to enhance the data used when performing LCA, LCC (life cycle costing), S-LCA (social life cycle assessment) or LCSA studies of FCH systems.
Accordingly, the main outcome of the topic will consist of a number of datasets developed for, and applied to, FCH product systems. Moreover, project results are expected to contribute to all of the following outcomes:
Project results are expected to contribute to the following objectives of the Clean Hydrogen JU SRIA for cross-cutting issues and the specific area on sustainability:
Given the importance of further enabling a robust and transparent assessment of FCH products to support the penetration of those in compliance with sustainability standards, this topic promotes the timely development of high-quality datasets for key FCH-relevant products and technologies across the hydrogen value chain. As regards scope, the project is expected to focus on the development of at least 20 high-quality, open-access and freely accessible datasets (LCIs) for several key FCH-relevant products and technologies. Besides, projects should also illustrate LCIs usefulness through their application in life cycle (sustainability) assessment studies.
The addressed materials, components, equipment, and technologies should be relevant to the hydrogen value chain, involve different technology readiness levels (thus including emerging technologies), and enable the assessment of a complete FCH system. In this regard, at least one entire FCH product system should be fully covered and assessed using both existing LCIs and the new ones to be built. When relevant, the developed inventories should address current data gaps regarding aspects such as critical raw materials, hydrogen losses, recycling, and end-of-life processes. According to current maturity in life cycle databases, inventory building should be relevant to at least the environmental dimension, while exploring opportunities for economic and social dimensions (which are subject to deeper geographical concerns).
The funded project should involve:
The expected consortium should involve experts in the field of LCA/LCSA of FCH product systems and FCH companies relevant to data acquisition. Letters of support from OEMs (original equipment manufacturers) should be made available at the proposal stage.
The datasets developed by the project for environmental LCA should be ready for their publication in the hydrogen node of the Life Cycle Data Network (LCDN)[6], which is managed by the European Commission’s Joint Research Centre (JRC).
Cooperation with the JRC and the European Hydrogen Sustainability and Circularity Panel (EHS&CP) should be foreseen. Moreover, synergy with other initiatives such as the IEA Hydrogen TCP Task 50 on Cost and Carbon Intensity Analysis and Model Comparison of Hydrogen Supply Chains[7] could be considered.

1. Admissibility Conditions: Proposal page limit and layout
described in Annex A and Annex E of the Horizon Europe Work Programme General Annexes.
Proposal page limits and layout: described in Part B of the Application Form available in the Submission System.
Page limit for Innovation Actions: For all Innovation Actions the page limit of the applications are 70 pages.
2. Eligible Countries
described in Annex B of the Work Programme General Annexes.
A number of non-EU/non-Associated Countries that are not automatically eligible for funding have made specific provisions for making funding available for their participants in Horizon Europe projects. See the information in the Horizon Europe Programme Guide.
3. Other Eligible Conditions
described in Annex B of the Work Programme General Annexes.
Additional eligibility condition: Maximum contribution per topic
For some topics, in line with the Clean Hydrogen JU SRIA, an additional eligibility criterion has been introduced to limit the Clean Hydrogen JU requested contribution mostly for actions performed at high TRL level, including demonstration in real operational environment and with important involvement from industrial stakeholders and/or end users such as public authorities. Such actions are expected to leverage co-funding as commitment from stakeholders. It is of added value that such leverage is shown through the private investment in these specific topics. Therefore, proposals requesting contributions above the amounts specified per each topic below will not be evaluated
Additional eligibility condition: Membership to Hydrogen Europe / Hydrogen Europe Research
For the topics listed below, in line with the Clean Hydrogen JU SRIA, an additional an additional eligibility criterion has been introduced to ensure that one partner in the consortium is a member of either Hydrogen Europe or Hydrogen Europe Research. This concerns topics targeting actions for large-scale demonstrations, flagship projects and strategic research actions, where the industrial and research partners of the Clean Hydrogen JU are considered to play a key role in accelerating the commercialisation of hydrogen technologies by being closely linked to the Clean Hydrogen JU constituency, which could further ensure full alignment with the SRIA of the JU. This approach shall also ensure the continuity of the work performed within projects funded through the H2020 and FP7, by building up on their experience and consolidating the EU value-chain. In the Call 2026 this applies to: development and demonstration of flexible and standardised hydrogen storage systems and demonstration and operation of reversible solid oxide cell systems operation for local grid-connected hydrogen production and utilisation. This will also apply to the Hydrogen Valleys (flagship) topics as they are considered of strategic importance for the European Union ambitions to double the number of Hydrogen Valleys by 2025 as well as to the more recent European Commission’s inspirational target to have at least 50 Hydrogen Valleys under construction or operational by 2030 across the entire EU. For the Hydrogen Valleys topics a large amount of co-investment/co-funding of project participants/beneficiaries including national and regional programmes is expected.
