This report was produced jointly by the unit JRC.C.1 of the European Commission and the Clean Hydrogen Joint Undertaking. It collects and summarises the work performed by the JRC for the 2025 Annual Programme Technical Assessment. This work was performed under the Framework Contract between the Clean Hydrogen JU and JRC signed on 29/11/2022. The Annual Assessment of the Programme is formal part of the regular improvement cycle of the Clean Hydrogen JU. It informs the decisions of future Annual Work Plans, by identifying gaps and possible improvement actions. It also provides feedback to the members of the Programme Office of the Joint Undertaking on the performance of the areas directly in their remits. The assessment evaluates the effectiveness and relevance of key performance indicators (KPIs) and their targets over a multi-annual period, identifying areas for refinement to inform future revisions. It also establishes a fact-check basis which can be used by other Programme Technical Assessments (for example the mid-term and the ex-post assessments). Finally, the data collection performed annually assists the assessment of long-term, historical progress of specific hydrogen technologies. This iterative approach ensures that KPIs remain adaptive to evolving program goals and technological landscapes. This Assessment Report has been structured around eight Strategic Research Innovation Agenda (SRIA) Pillars, representing the major action lines of the multi-annual programme of the Clean Hydrogen JU. Each of these Pillars have been assessed, according to an established JRC methodology. The major achievements of the projects in each Pillar were summarised in the ‘Highlights’ sections, compared with the Pillar objectives and put in a multi-annual perspective. The progress against the SRIA targets was also assessed. A dedicated State of the Art (SoA) section is included, providing an overview of the international landscape relevant to the specific area and referencing other European projects addressing the same research topic. Based on these insights, pillar-specific gaps were identified to guide future improvements and actions, resulting in a set of pillar-specific recommendations, as well as overarching recommendations applicable across all pillars.
