RWE Gas Storage West is starting to market the last available capacities in the Epe H2 hydrogen storage facility

RWE Gas Storage West GmbH (RGSW) is starting to market the last available storage capacities in the hydrogen storage facility currently under construction at the Gronau-Epe site. RGSW is launching a binding tender on 16 June. This is aimed at companies that wish to secure available storage capacity for hydrogen from 1 January 2028.

Construction work on Germany's first commercial hydrogen storage facility is already underway. RWE will fill the first cavern with hydrogen from mid-2026. At the same time, hydrogen will be used to pressurise the brine from a second cavern so that it can also be used for storage. Once completed, the storage facility with its two caverns will have an injection and withdrawal capacity of 50,000 cubic metres per hour and a working gas volume of around 38 million cubic metres. Around 70% of this has already been marketed. Commercial storage operations will start on 1 July 2027.

The current tender is for the 30% storage capacity that, for technical reasons, will not be available until 2028. In a market survey in spring 2025, RGSW asked potential customers about their requirements. The findings from this survey have been incorporated into the tender.

Transport and storage infrastructure will play a key role in the ramp-up of the hydrogen economy: storage facilities help to buffer the fluctuating hydrogen production from wind and solar power. This will enable hydrogen produced in the future to be made available to industrial customers as needed.
