Underground Thermal Energy Storage (UTES) is a powerful set of solutions that allows efficient management of thermal energy sources, both heat and cold, the demand of which is subjected to seasonal variations. Underground can store available in excess heat or cold for periods of up to several months and use whenever needed, especially in the opposing season. Sources of thermal energy that can be stored underground are, among others: solar thermal energy, cold winter air, waste heat from ventilation and waste heat from industrial processes. Two primary methods of under ground energy storage are Aquifer Thermal Energy Storage (ATES) where water reservoir is a thermal energy accumulator and Borehole Thermal Energy Storage (BTES) where rock formation acts as a heat/cold store. UTES allows to minimizing consumption of fossil fuels and therefore reduce costs of energy purchase, limiting the amount of greenhouse gases emission into atmosphere, and increasing energy security.
