BTES (borehole thermal energy storage). BTES stores can be constructed wherever boreholes can be drilled, and are composed of one to hundreds of vertical boreholes, typically 155 mm (6.1 in) in diameter. Systems of all sizes have been built, including many quite large.
Seasonal storage typically requires considerable planning and co-ordination between end-use demands and energy resources, and it is economically viable only when costs are low, given that the storage systems charge or discharge so infrequently.
For cooling applications, often only circulation pumps are used. Sorption and thermochemical heat storage are considered the most suitable for seasonal storage due to the theoretical absence of heat loss between charging and discharging. However, studies have shown that actual heat losses currently are usually significant.
Warm-temperature seasonal heat stores can be created using borehole fields to store surplus heat captured in summer to actively raise the temperature of large thermal banks of soil so that heat can be extracted more easily (and more cheaply) in winter.
