Kurzbeschreibung (Abstract)
The federal government of Germany has committed itself to ambitious climate protection goals in international treaties. Achieving these goals is only possible with the inclusion of all renewable energies. So far, geothermal energy plays hardly any role in the expansion of renewable energies, whereas some regions of Germany and Hesse are well suited for geothermal energy. The state of Hesse is rich in thermal springs, some of which have been used for various purposes for centuries. But little effort is made to exploit these hydrothermal systems geothermal. One reason might be that the exploration of geothermal reservoirs and the assessment of underground properties is still a major challenge. The establishment of a hydrochemical database on reservoir fluids provides parameters for the evaluation of hydrothermal systems. The data are derived from a comprehensive literature research in cooperation with the HLNUG and the BGR. Hydrochemical data sets from the Hessian territory that meet one of the following criteria and are not older than 1910 have been added to the database: -water temperature at least 20 °C (definition thermal water) -solution content at least 1 g/l (definition mineral water) -depth at least 100 m (definition of the future formation water database of the BGR) The database contains thousands of data sets with metadata (coordinates, altitude, tapping type, etc.), references (analysis date, citation, etc.), physical parameters (like temperature, electrical conductivity, pH), chemical parameters (concentrations of ions and elements), sum parameters, dissolved and free gas contents, as well as isotope data. In a first evaluation step, the database is used to assess the distribution and composition of mineral and thermal waters. The most important criteria for this are the water type (e. g. Ca-HCO3 or Na-Cl waters), the water temperature, the salinity, the CO2 concentration and the depth of the tapping. In a second step, hydrothermal provinces are defined for Hesse and adjacent regions. Within a province, the water quality is similar, so it can be assumed that the genesis of the fluid is also similar. In a third step, hydrothermal potentials can be identified.
