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.
