The demo operation of hydrogen production and storage in the USS2030 project has been successfully completed, showing that it is technically possible to offer hydrogen storage services on a scaled and commercial basis in depleted underground gas reservoirs.
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 – and its project partners are setting new international standards.
In the lead project "Underground Sun Storage 2030" (USS 2030), the safe, seasonal and large-scale storage of renewable energy in the form of hydrogen in underground gas reservoirs is being developed. In addition, all partners involved in the project will jointly gain valuable technical and economic knowledge for the development of a secure hydrogen supply.
