As part of the EU GEOTHERMICA – ERA NET Cofund project HEATSTORE, important lessons learned and operational experience from existing High-Temperature Aquifer Thermal Energy Storage (HT-ATES), Borehole Thermal Energy Storage (BTES) and Pit Thermal Energy Storage (PTES) have been compiled together with Mine Thermal Energy Storage (MTES) current state of technology. Through a literature study and based on actual experience and know-how among the HEATSTORE project partners, relevant cases in, and outside, Europe have been described. Essential learnings covering the entire process from the first pre-investigation phase and feasibility studies through the construction phase, system integration and operations as well as different national legislative, political and public issues are summarized.
