The Rheinfelden Electrolyser Project is a renewable hydrogen production project located in Rheinfelden (Baden), Germany. The facility will consist of a 100 MW electrolyser (2 times 50 MW) and will primarily supply renewable hydrogen to industrial consumers in Germany. The project will use electricity from the grid, supported by renewable energy sources PV and wind generation.
The project will connect to Germany’s hydrogen core network, enabling hydrogen transport to customers in Germany and over the time facilitating cross-border hydrogen transport to neighbouring countries including France, Switzerland, Austria and Liechtenstein.

The project has been included on the European Union’s Projects of Common Interest and Projects of Mutual Interest (PCI/PMI) list and is progressing through engineering and permitting activities.
The permit granting process will be carried out in accordance with German and European regulatory requirements.

Stakeholder engagement and public consultation activities will be conducted throughout project development.
Information concerning consultation periods, project documentation and stakeholder events will be made available on this website as required by the permitting process.

The Rheinfelden project is included on the Second Union List of Projects of Common Interest (PCI) and Projects of Mutual Interest (PMI) adopted in April 2026 under reference number 9.18.3. The project has been identified as a strategic energy infrastructure project supporting the development of an integrated European hydrogen network and contributing to the EU’s decarbonisation objectives.
A key feature of the project is that its location near the border in the tri-border region between Germany, Switzerland, and France provides excellent access to European hydrogen customers, thereby ensuring a stable and sustainable industrial supply.
