Flag ship project - RAG Large-volume storage of hydrogen enables energy transition while maintaining security of supply. With "Underground Sun Storage", the world's first hydrogen storage facility in an underground porous reservoir, RAG Austria AG - Renewables and Gas, together with its project partners, is setting new international standards.
Underground Sun Storage - The lead project "Underground Sun Storage 2030" (USS 2030) is developing the safe, seasonal and large-volume storage of renewable energy in the form of hydrogen in underground gas reservoirs. In addition, all partners involved in the project will gain valuable technical and economic knowledge for the development of a secure hydrogen supply.
HyStorage - Uniper Bierwang, Investigation of the influence of different hydrogen concentrations on porous rock formations and thus verification of the suitability and integrity of porous reservoirs for the storage of hydrogen. Since the fall of 2023, sample holders (developed by voestalpine Tubulars) for material samples have also been installed in this test series, enabling the effects on samples under tension to be tested in situ.
HPC Krumhörn. The HPC Krummhörn project aims to test the design and operation of a 100% hydrogen storage facility under real conditions. During the test operation, we are testing equipment, materials and materials for H2 compatibility and gaining experience in the technology and operation of hydrogen storage. We will use a salt cavern storage facility in Krummhörn, Germany. The demonstration plant is scheduled to go into operation in 2024.
