Starting with 2022, the scope of the Programme Review has further broadened compared to previous years. At the core of the Programme Review remains still the Annual Programme Technical Assessment performed by the JRC; its recommendations are then complemented by the independent opinions of the wider scientific community, gathered during the EU Hydrogen Research Days as well as the input of the JU’s Stakeholders Group, on the strategic and technological priorities to be addressed by the Clean Hydrogen JU. Additionally, the Programme Review reports on relevant studies commissioned by the JU, reports published by international bodies and selected international developments, providing a more holistic picture on the wider developments in the hydrogen sector and how the Clean Hydrogen JU activities fit in this wider context.

The Programme Review covers 98 projects active between January 2021 - March 2022, which have been assigned to seven thematic pillars: Hydrogen Production, Hydrogen Storage and Distribution, Hydrogen End Uses – Transport, Hydrogen End Uses – Clean Heat and Power, Cross-Cutting Issues, Hydrogen Valleys and Hydrogen Supply Chains.

The report highlights numerous achievements of these projects in all areas of the hydrogen value chain.
