GEOTHERMAL ENERGY SITUATION IN GALICIA

The use of geothermal systems in Galicia, focuses on HVAC systems and thermal
water, using low and very low enthalpy geothermal resource.
Geothermal energy of very low enthalpy, with temperatures of just a few degrees is
available anywhere on our planet, but like any other mining resource its use
depends on the geological conditions of the area where its use is intended. In the
case of the Galicia, the existence of a subsoil with predominance of crystalline
rocks of high thermal conductivity (granites), easily drivable and with a very
shallow water table, makes that practically all its territory is optimal for the
implementation of the Ground Source Heat Pump.

Objectives: answering environmental concerns in terms of both impacts and risks, by
first setting an adapted methodology for assessing environment impacts to the project
developers, and by assessing the environmental impacts and risks of geothermal
projects operational or in development in Europe. The project will propose
recommendations on harmonised European environmental regulations to the decision-
makers and elaborate simplified LCA models to assess environmental impacts.
