Abstract

Summary

The geothermal resources of Germany are limited to intermediate and low enthalpy resources (below 200 °C). The hydrothermal resources are predominantly used for balneological applications, space and district heating and even for power production at currently nine sites. Besides balneology, the confined aquifers in northern Bavaria also hold the potential for energy storage.

Therefore, available data was collected and interpreted with the objective to map the hydraulic conductivity of aquifers and to integrate these maps into the Geothermal Information System (GeotIS), a public web-based information system for geothermal project planners, scientists, municipal energy suppliers, and public authorities. About 80 % of all sampling sites show transmissivity and hydraulic conductivity values sufficient for geothermal energy utilization or energy storage. For the Keuper aquifer, even 95% of all sampling sites show transmissivities sufficient for geothermal energy utilization.

These maps do not replace a feasibility study because detailed geological site assessment is still essential when planning a new geothermal facility. As part of this study, a lot of processed geological, hydraulic, and subsurface temperature data will be transferred to the Geothermal Information System GeotIS.
