Germany has three regions that are particularly well situated for geothermal energy use: the North German Basin, the Upper Rhine Graben, and the South German Molasse Basin. Each of these regions has characteristic features that pose different challenges for using geothermal heat. The main features of the thermal water in the North German Basin are its moderate flow rates and temperatures and in places very high salinity; whereas in the South German Molasse Basin there are some high flow rates, high temperatures and mostly low salinity. The heterogeneous geology and numerous fault zones of the Upper Rhine Graben make it more difficult to develop; but, its high temperatures and flow rates mean it has good, possibly even the best, conditions in Germany for commercial use of geothermal energy.
