The paper "How to deliver on the EU Hydrogen Accelerator" analyses the Hydrogen Accelerator proposed in the European Commission’s REPowerEU common action plan and suggests concrete additional EU actions that are needed to realise its ’20-Mton-hydrogen-target-by-2030’, i.e., 10 Mton produced in the EU and 10 Mton supplied via imports. The aim of these efforts in support of ‘REPowerEU’ is to make the Union 25-50 BCM less dependent on Russian gas.
