PCI status for EWE’s hydrogen storage projects underscores the key role of storage for Europe’s hydrogen infrastructure
In December 2025, three hydrogen storage projects developed by EWE in Huntorf, Jemgum and Rüdersdorf were granted Project of Common Interest (PCI) status and included in the second Union PCI-PMI list under the revised Trans-European Networks for Energy (TEN-E) Regulation. The projects aim to strengthen the European hydrogen infrastructure by providing large-scale underground storage capacities that are essential for balancing supply and demand, enhancing system flexibility, and ensuring security of supply in a future hydrogen-based energy system.
Hydrogen storage plays a key role in the development of a resilient and integrated European hydrogen market, as it enables the temporal decoupling of hydrogen production from consumption and supports the integration of renewable energy sources. The PCI status highlights the strategic relevance of these projects at European level and provides important benefits such as accelerated permitting procedures, enhanced cross-border coordination, and eligibility for funding under the Connecting Europe Facility (CEF), thereby supporting the timely implementation of critical hydrogen infrastructure.
