The same is true on a national or even regional scale. Excepting smaller scale heat storage using phase change and other materials, which can be transported (Pielichowska and Pielichowski, 2014), thermal energy storage and retrieval in underground mines and aquifers must therefore focus on a local or regional scale. In consequence it is

Aquifer Thermal Energy Storage

Aquifer thermal energy storage (ATES) is a natural underground storage technology containing groundwater and high porosity rocks as storage media confined by impermeable layers. Thermal energy can be accessible by drilling wells into such aquifers. The drilling depth is reported up to 1000 m, but the median value is 200 m (Fleuchaus et al., 2021).

Research progress of seasonal thermal energy storage

In aquifer thermal energy storage, geological strata serve as the storage medium and groundwater serves as the heat transport fluid. Aquifer thermal storage can be divided into two types: high-temperature aquifer thermal storage and conventional aquifer thermal storage. In addition, the type of thickening agent, the amount added and the
