The Electricity Hub: RAG Launches World’s First Underground Green Hydrogen Storage Facility

Gas storage company, RAG Austria has launched a demonstration project in Upper Austria to show how green hydrogen can be stored in an underground natural gas reservoir.

In Austria’s northern Gampern municipality, the system was finished two years after the project began. According to RAG’s statement from last week, it has the ability to store 4.2 GWh of summertime solar energy as hydrogen for use in the winter. This is the first hydrogen storage system of its kind in the world, according to the business.

By using this facility, extra solar energy from about 1,000 single-family houses can be converted into hydrogen and stored for the winter and summer.
