GEOTHERMAL

Geothermal resources exist everywhere. At or near the surface they can be harnessed using trenches or shallow boreholes and Ground Source Heat Pumps. At greater depths, depending on the geothermal gradient, temperatures from a few tens of degrees Centigrade to several hundred degrees can be encountered within sensible drilling range and the heat can be used for anything from moderate temperature direct use to large capacity electricity production.

The heat is accessed by drilling holes or ‘wells’ into the geothermal reservoir and circulating water through the rocks to bring it to the surface, where it can be used directly or passed through heat exchangers before being reinjected back into the ground.

Geothermal energy is a mature technology that has been used for decades to provide renewable heat and power in a commercially attractive and environmentally sensitive way.
