We are happy to announce that EUH2STARS has taken over operations at the Rubensdorf site with the beginning of May 2025. The successful conclusion of two storage cycles within the previous project "Underground Sun Storage 2030" marks the start for four further storage cycles within EUH2STARS.

The first cycle started at the beginning of May 2025 and three more cycles are to be conducted until 2029. The learnings from "USS2030" build a valuable basis for EUH2STARS and we are confident that operations will continue successfully.
