Publication in the International Journal of Hydrogen Energy: Scientific confirmation of the successful demonstration of Underground Sun Storage
The scientific paper documents the results of the Underground Sun Storage 2030 demonstration project and describes the world’s first successful demonstration of the storage of pure hydrogen in an underground natural gas reservoir
With this newly published and citable paper, the results of the demonstration operation are not only scientifically documented but also validated through an international peer-review process.

Ground-breaking ceremony for Austria’s largest green hydrogen production plant:
- RAG Austria are expanding together with Andritz the electrolysis facility at RAG Valley Gampern (Upper Austria) from 2.5 MW to 15 MW.
- Winter 2025/26 makes it clear: massive dependence on imports for electricity supply cannot be resolved through wind power expansion or battery and pumped-storage solutions – gas storage facilities and power stations have maintained supply.
- An integrated energy system comprising renewable generation, storage and energy use is urgently needed in Austria.
- RAG Valley Gampern had already demonstrated in the winter of 2025/26 how solar power generated in the summer could be stored and used in the winter – a solution that is now being scaled up further.
- Strengthening regional industry through the consistent scaling up of green hydrogen production
Electrolyzes convert domestic solar power into a storable energy carrier, which is why I wholeheartedly welcome the project in Gampern.

It's time: Thinking about winter during summer
RAG Austria uses surplus energy from the summer and stores it for the winter in the form of hydrogen. With our innovative technologies and clear regulatory framework, we can
- reduce our dependence on energy imports,
- green the gas,
- drive the roll-out of hydrogen efficiently and sustainably, and
- ease the strain on the electricity grids.
“We have been shaping the energy world for nine decades, successfully ensuring security of supply, driving innovation and pointing out new paths and prospects for the future.”
