RWE Gas Storage West GmbH (RGSW) has initiated the process of marketing free storage capacity for hydrogen at the Gronau-Epe site in North Rhine-Westphalia, Germany. The company is set to launch a binding tender on 16 June for companies interested in securing storage capacity for hydrogen from January 1, 2028. The construction of Germany's first commercial hydrogen storage facility is already in progress, with RWE planning to fill the first cavern with hydrogen by mid-2026. Additionally, hydrogen will be used to displace brine from a second cavern to prepare it for storage. Once completed, the facility will have a substantial injection and withdrawal capacity of 50,000 cubic meters per hour and a working gas volume of around 38 million cubic meters, of which 70% has already been allocated. The remaining 30% of storage capacity will be made available in 2028 due to technical reasons, and a recent market survey has guided the current tender process. This strategic development in energy infrastructure underlines the importance of storage facilities in stabilizing hydrogen production from renewable sources like wind and solar energy. The RWE Epe-H2 hydrogen storage facility is poised to enhance the hydrogen economy by ensuring flexibility in supplying industrial customers with hydrogen as required.
