VESTA - Very-High-Temperature Heat Aquifer Storage

Energy storage is one of the key challenges of the energy transition. Eight international partners from Germany, Switzerland and the USA address this challenge in the joint project VESTA. Goal of VESTA is the generic development and demonstration of high-temperature storage in the underground. Four pilot sites in the DACH region in various geologies and project phases allow feedback loops between generic scientific investigations and application of new geothermal technologies. Specifically, pilot sites that shall 1) demonstrate HT-ATES technology, 2) evaluate technical and non-technical barriers, 3) support development and implementation by providing techniques and optimized component design, and 4) support agencies with scientific and technical knowledge as a basis for advancing regulatory provisions. With this scientific program, VESTA shall form a technical-economic bases for future operational concepts.
