RWE Gas Storage West GmbH in Gronau-Epe, North Rhine-Westphalia, has initiated the marketing of available storage capacity at its hydrogen storage facility, targeting companies interested in securing hydrogen storage from January 2028. This marks the development of Germany's first commercial hydrogen storage site. The facility is in progress with RWE aiming to fill the first cavern with hydrogen by mid-2026 while also displacing brine from a second cavern to prepare it for hydrogen storage. The facility will provide a significant working gas volume of 38 million cubic metres and an injection/withdrawal capacity of 50,000 cubic metres per hour, with 70% of this capacity already assigned. A binding tender, launched in June, addresses the remaining 30% of capacity, set for availability in 2028 due to technical constraints. The offer has been influenced by insights from a market survey conducted in spring 2025 to align with customer requirements. Commercial operations are scheduled to commence on 1 July 2027, showcasing a strategic step towards hydrogen infrastructure development in Germany.
