HyStorage project unlocks Bavaria’s hydrogen storage potential

Hydrogen

Germany – HyStorage project has marked the completion of its first operating phase, showcasing the viability of utilizing Bavarian porous rock formations for hydrogen storage.

Partner companies, including Uniper and OGE, presented interim results, revealing a 90% recovery of injected hydrogen without impacting reservoir performance.

The overarching goal of the HyStorage project is to assess the feasibility and integrity of porous rock formations, specifically in southern Germany’s Alpine Molasse Basin, for storing hydrogen. Hydrogen storage is increasingly recognized as an essential element in the transition to a decarbonized energy market.

The project involves three cycles with varying hydrogen concentrations (5%, 10%, and 25%) injected into former natural gas reservoirs. The success of the first phase, with a 5% hydrogen blend, establishes a foundation for further testing and development. Material testing during the process has demonstrated the resilience of materials against hydrogen corrosion, a critical aspect for the long-term viability of hydrogen storage.

HyStorage impact

The successful recovery of almost 90% of injected hydrogen during the initial phase bodes well for the potential impact of HyStorage on the hydrogen landscape. If subsequent phases validate these results, it could pave the way for larger-scale hydrogen storage projects. The stored hydrogen has the potential to play a crucial role in ensuring a stable and secure energy supply, especially during periods of high demand or when renewable energy sources are intermittent. Additionally, this project aligns with the broader European push for hydrogen as a clean energy carrier.

The support from Bavarian Minister of Economic Affairs, Regional Development, and Energy, Hubert Aiwanger, underscores the project’s significance for Bavaria and the broader energy industry. The collaboration of experienced European project partners, including Uniper, OGE, RAG Austria, SEFE Securing Energy for Europe, and NAFTA, along with interdisciplinary support from industry and science, ensures a robust evaluation of the project’s results.
