Areas of use for hydrothermal heat generation

The topic provides an overview of the suitability of areas for heat generation by hydrothermal geothermal energy. Areas with favourable and possibly less favourable geological conditions (mostly required additional heat pump use) are distinguished. According to today’s knowledge, the greatest potential for hydrothermal heat generation lies in the malm of the southern German Molasse basin. The areas of use are based on a blend of temperature maps of different depths with the depth of the Purbeck or Malm surface (border criteria 40 and 70 °C respectively). The geometries of the areas of use are generalised and designed for the viewing scale 1:250,000. The data set provides a basis for large-scale considerations and does not replace the conduct of detailed investigations.
