HEATSTORE aims at developing High Temperature (~25°C to ~90°C) Underground Thermal Energy Storage (HT-UTES) technologies, which are crucial for the energy system transformation to be successful. Storing heat underground will allow to manage variations in heat supply and demand and store energy for future use. In Switzerland, HEATSTORE focuses on two demonstration projects for High Temperature Aquifer Thermal Energy Storage (HT-ATES). Scientists from the Universities of Geneva, Bern, Neuchâtel and the Swiss Federal Institute of Technology in Zurich (ETHZ) are working on this project in collaboration with industrial operators (Services Industriels de Geneva SIG and Energie Wasser Bern EWB) within the framework of the SCCER-SoE to assess the feasibility of HT-ATES systems in Switzerland.
For the energy transition to succeed, low carbon heat sources need to be established. Heat storage is essential in this development, because it provides the flexibility to manage the variations in supply and demand of heat (for example seasonal changes in heat demand). Additionally, excess heat produced by industrial and civil activities, until now was emitted to the environment, could be stored underground for seasonal supply. It is the main objective of the HEATSTORE project to further develop HT-UTES technologies.
In Switzerland, HEATSTORE aims at conducting two demonstration projects for High Temperature Aquifer Thermal Energy Storage (HT-ATES), where industrial waste heat is converted into a resource. The demonstration projects are located in the cantons of Geneva and Bern.
The HEATSTORE demonstration projects form part of the SCCER-SoE. Scientists from the Universities of Geneva, Bern, Neuchâtel and the Swiss Federal Institute of Technology in Zurich (ETHZ) tackle the question whether HT-ATES will be feasible or not. They closely collaborate with two industrial partners, the Services Industriels de Geneva (SIG) and Energie Wasser Bern (EWB).
