This paper analyses the Hydrogen Accelerator proposed in the European Commission’s REPowerEU common action plan and suggests concrete additional EU actions are needed to realize its ’20-Mton-hydrogen-target-by-2030.’ Key recommendations include establishing a European Hydrogen Cross-Border Infrastructure and Storage Facility that complements those of EU Member States, to develop pipelines, port facilities, and strategic hydrogen reserves. Further actions involve developing hydrogen demand per geographical area through ‘gas-to-hydrogen infrastructure conversion,’ creating a temporary Global European Hydrogen Facility to support domestic production and imports of renewable hydrogen, and having the Global European Hydrogen Facility use the H2Global mechanism to strengthen market liquidity and supply.
