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. In ATES systems, groundwater is used to carry thermal energy to and from an aquifer, using water wells and storing the heat in the groundwater and in the solid mass around it (Figure 1.7) [17]. This is a commercial technology, with the Netherlands and Sweden as leading countries in terms of implementation. The systems are usually for low temperature building applications. BTES systems have several closely spaced boreholes, between 50 and 200 m deep; they act as heat exchangers to the underground, usually in U-pipe form (Figure 1.8) [17]. There are many countries with thousands of BTES systems, ranging from one borehole to up to a few hundred boreholes, usually for heating and cooling of buildings (residential housing and hotels and office buildings). Another UTES system is energy piles, which use the building foundations as ground heat exchangers [18]. Countries such as Japan see this method as having a lot of potential because it allows cost reduction in the construction of the ground heat exchangers. Energy piles are cast-in-place concrete piles, precasting concrete piles, and steel foundation piles.
