Geo-Energie Suisse AG has developed the multi-stage geostorage facility together with Energie Wasser Bern. Since the pilot project Geospeicher Forsthaus (Bern) is a pilot and demonstration project, it is not yet economically viable on its own. Due to its importance for the desired energy transition, the project is funded by the federal government as a pilot and demonstration project within the framework of GEOTHERMICA.
