Overview
- Hamburg laid the foundation for a 100 MW Siemens PEM electrolyser at the former Moorburg coal site, backed as an IPCEI project with about €154 million and aiming for 2027 startup with roughly 10,000 tonnes per year.
- EWE started construction in Emden by awarding civil and structural contracts for a 320 MW electrolyser under Clean Hydrogen Coastline, planning initial industrial supply by late 2027 and about 30,000 tonnes annually.
- The Emden build-out pairs production with a converted Huntorf salt cavern for large-scale storage and pipeline links between Wilhelmshaven, Leer and Emden into Germany’s hydrogen core network and the European Hydrogen Backbone.
- Hamburg’s hub will serve customers via the HH-WIN distribution grid and a planned trailer loading station, with the site prepared for later capacity expansion beyond the initial 100 MW.
- Project leaders call for RFNBO rule updates, competitive power prices and demand signals to secure viability, reflecting an October audit that found Germany’s hydrogen rollout falling behind targets.
