RWE Gas Storage West - RWE H2-storage Gronau-Epe (DE24)

RWE H₂-storage Gronau-Epe

Within the GET H2 IPCEI consortium, 8 companies have joined forces with the common goal of establishing a first hydrogen large scale value chain for hydrogen in West Germany. It consists of hydrogen production, transport and storage as well as its connection to first industrial end users. RWE Gas Storage West's project, the construction and operation of a large-scale hydrogen storage facility, completes the hydrogen value chain with the necessary flexibility. This allows the enlargement of the associated hydrogen cluster and the perspective connection of hydrogen clusters in Europe. Thus, the project makes a significant contribution to the development of the European Hydrogen Backbone. 

RWE Gas Storage West’s project aims to use two salt caverns for the storage of renewable hydrogen at the RGSW site in Gronau-Epe, Germany. The storage plant will have a capacity of 135 GWh and will be capable to inject and withdraw 50,000 Nm³/h (approx. 4,500 kg/h) of hydrogen and to store up to 38 million Nm³ (3,420 tonnes) of hydrogen working gas volume in two salt caverns. The caverns are expected to be commissioned and available for commercial utilisation in 2027. Refineries and companies operating in industrial sectors such as the steel industry will be the most important customers. The project plans to have a cross-border connection to the Dutch hydrogen backbone.

The H₂ storage will be located in Gronau-Epe in Germany. Detailed planning and the application for the necessary permits to implement the project started in June 2022. Directly after the necessary permits were obtained, the construction work itself began. The caverns will be filled with hydrogen for the first time in 2026, meaning that the hydrogen storage facility will go into commercial operation in 2027.
