Summary

Warm geothermal fluids at a depth of 500 to 3000 m can range in temperatures from 20 to 100 deg C and provide a valuable source of renewable energy. The first large-scale project for utilizing this so-called hydrogeothermal energy in Switzerland, has been operating since 1994. Using heat pumps, geothermal water at 65 deg C is used to supply a communal district heating network in a residential suburb of Basel. The results so far are very good. The availability forecast have been reached and the consumption of fossil fuels has been reduced to less than a half.
