EWE Hydrogen Storage Rüdersdorf
The project comprises the development of the EWE Hydrogen Storage Rüdersdorf in Rüdersdorf, in the federal state of Brandenburg (Germany) and aims to establish Germany’s first underground storage facility dedicated exclusively to hydrogen. The project includes the conversion of one existing natural gas salt cavern to hydrogen service and the construction of two new salt caverns designed for hydrogen storage, together with the required above-ground process and utility infrastructure, with one of the newly developed caverns realized by extending an existing well and the HyCAVmobil test cavern, while the second cavern will be newly drilled, leached, and completed.
Upon completion, the storage facility will provide a total working gas capacity of approximately 455 GWh, with combined injection and withdrawal capacities of up to 12 GWh per day. The project integrates repurposed natural gas infrastructure and newly constructed hydrogen assets, using hydrogen-compatible materials and safety-relevant technical equipment to ensure long-term integrity, safe operation, and scalability as a core element of future hydrogen infrastructure.
