Seasonal thermal energy storage

Appearance. hide. Seasonal thermal energy storage ( STES ), also known as inter-seasonal thermal energy storage, [1] is the storage of heat or cold for periods of up to several months. The thermal energy can be collected whenever it is available and be used whenever needed, such as in the opposing season. For example, heat from solar …

Geothermal technologies

Geothermal resources can be broadly grouped into shallow and deep geothermal. Shallow geothermal energy is the low-grade heat (10 to 25°C) that is stored in the shallow subsurface at depths of up to 500 m. It requires the use of ground-source heat pumps and can be used in most parts of the UK for the heating of buildings.
