Rajandrea Sethi, in Encyclopedia of Energy Storage, 2022 The expression Underground Thermal Energy Storage (UTES) identifies shallow geothermal systems where heat from external sources (solar thermal collectors, industrial processes, combined heat and power systems) is stored seasonally into the ground to be used during periods of higher demand.
We suggest to launch the European Underground Thermal Energy Storage Alliance as part of the mission to bring Europe to the forefront of HT-UTES technology development and valorise the market Surface installation of the HT-ATES in Middenmeer, the Netherlands with connection to the heat network.

Underground thermal energy storage (UTES) uses the ground to store heat and cold. Depending on the geological, hydrogeological and other site conditions, ATES (aquifer TES), BTES (boreholes TES) or CTES (cavern TES) is selected as a storage system. ATES and BTES are commercial today, CTES is rarely applied commercially.
The experience of USTES applications worldwide in recent years shows that most of the solar energy seasonal storage projects have significant economic, social and environmental benefits. However, the key part of solar energy storage system is underground.
Ibrahim Dincer, Marc A. Rosen, in Exergy Analysis of Heating, Refrigerating and Air Conditioning, 2015 Underground heat storage, or underground thermal energy storage (UTES), has storing temperature range from around 0 °C to up to 40-50 °C. This operating temperature range is suitable for heating and cooling applications in HVAC.
The underground is suitable for thermal energy storage because it has high thermal inertia, i.e. if undisturbed below 10-15 m depth, the ground temperature is weakly affected by local above ground climate variations and maintains a stable temperature [ 76, 77, 78 ].
