From Geothermal Energy
Geothermal systems exploit heat from underground to produce energy for heating purposes, and where geothermal temperatures are sufficiently high, this heat can be used to generate electrical energy. The term surface geothermal is used to refer to sources down to a depth of 400 metres, below that we use the term deep geothermal. In the field of geothermal energy gec-co is involved exclusively with deep geothermal projects for the production of heating energy and/or electricity. There is also a distinction between hydrothermal geothermal energy, where water-bearing underground strata are present, and enhanced geothermal systems (EGS) where man-made heat exchangers are created underground.
So far the enormous potential of geothermal energy remains largely untapped. In Germany the South German Molasse Basin, the North-German Basin and the Upper Rhine Rift offer good potential for utilising deep geothermal energy.
Geothermal energy is a renewable energy source. Based on today’s knowledge the usable resources are unlimited. Base-load capability and being independent from seasonal influences are additional important characteristics of geothermal energy.
Geothermal energy is a domestic energy source – no global-warming fuel transports are necessary. Geothermal energy also offers the prospect of energy independence as it does not rely on the availability of fuels nor on deliveries of oil or gas.
Geothermal energy is a carbon-free energy source.
Being base-load capable, geothermal can be combined in a useful way with other renewable energy sources.
