    Thermal energy storage technologies need to be further developed and need to become an integral component in the future energy system infrastructure to meet variations in both the availability and demand of energy. The main objectives of project HEATSTORE are to lower the cost, reduce risks, improve the performance of high temperature (~25°C to ~90°C) underground thermal energy
    storage (HT-UTES) technologies and to optimize heat network demand side management (DSM). This is primarily achieved by 6 new demonstration pilots and 8 case studies of existing systems with distinct configurations of heat sources, heat storage and heat utilization. It will advance the commercial viability of HT-UTES technologies and, through an optimized balance between supply, transport, storage and demand, enable geothermal energy production to reach its maximum deployment potential in the European energy transition.
