Services - Geothermics

Geothermics is based on the use of the Earth’s interior heat.

There are two types of geothermal energy:

Medium-enthalpy geothermal energy is collected from resources at moderately elevated temperatures to be used, for example, in district heating systems.

High enthalpy geothermal energy is currently used for the direct production of clean electrical power in appropriate areas where the geothermal gradient can reach 200ºC/km.

Shallow or low and very low enthalpy geothermal energy takes advantage of the absence of seasonal temperature changes at low depths to perform heat exchange in HVAC and hot water systems connected to geothermal heat pumps. This clean and sustainable option exists in the subsoil of any land in any inhabited area on earth and its use is ecological, affordable and sustainable in single family homes as well as buildings and large retail stores.

In this connection, CGS offers a wide range of services directed at making the most of the geothermal potential of subsoil.

Deep Geothermics

Since 1979, CGS has carried out numerous research studies on geothermal resources and potential in Spain (Asturias, the Balearic Islands, the Canary Islands, Cantabria, Catalonia, Ciudad Real, Huesca, La Rioja, Madrid, Orense, the Basque Country and Valencia).
