| Abstract |
The geothermal resources and reserves have been estimated for selected aquifers in the Northwest German Basin, the Upper Rhine Graben and the South German Molasse Basin. The highest reserves are located in the Malm aquifer in the Molasse Basin. Geothermal energy is utilized in 15 localities using low enthalpy water. The total installed capacity is about 8 MWt. Two small new installations (Waldsee, Weiden) have been realized in the last years. In another project (Bruchsal) the doublet, which is necessary because of the high saline water, is now in working order. A prefeasability study for a Hot Dry Rock system has been performed by a German-French group. The HDR test site is located in the Upper Rhine Graben. |
