EWE Hydrogen Storage Jemgum  

The EWE Hydrogen Storage Jemgum project is located in Jemgum, in the federal state of Lower Saxony (Germany), and aims to develop a large-scale underground hydrogen storage facility at an existing storage site. The project focuses on the construction of multiple newly built hydrogen storage caverns, including the development of the required above-ground process and utility installations, thereby contributing to the expansion of hydrogen storage capacities in north-western Germany. 

The implementation of the project is foreseen to be carried out in several phases. In an initial development stage, several caverns are planned to be brought into operation, providing a substantial working gas capacity. In subsequent phases, the storage facility may be further expanded through the addition of further caverns, significantly increasing the overall hydrogen storage capacity of the site in the medium to long term. 

Located within the HI West hydrogen corridor, the project benefits from a strategically favourable position with good connectivity to the emerging hydrogen core network and existing large-scale transport infrastructure. The storage facility is designed to provide flexibility for the hydrogen system and to support security of supply by enabling large-volume, seasonal hydrogen storage. Depending on market demand, the stored hydrogen can contribute to cross-border supply and be marketed on a non-discriminatory basis, supporting the development of an integrated and resilient European hydrogen market.
