RAG-Wasserstoffspeicher Rubensdorf

With “Underground Sun Storage”, the first hydrogen storage facility in an underground porous reservoir was opened in Rubensdorf in April 2023. In this unique cross-sector demonstration plant, solar energy is converted into green hydrogen by means of electrolysis and stored in pure form in an underground natural gas storage facility in Gampern, Upper Austria.

The storage volume amounts to 4.2 million kWh (4.2 GWh) and corresponds to the summer surplus of around 1,000 photovoltaic systems on single-family homes. The Rubensdorf storage facility was connected to the RAG site in Gampern/Puchkirchen by an almost 8 km long pipeline.
