Finding heat deep underground

30. August 2011

Online geothermal information system provides access to basic data

At many places in Germany, deep geothermal heat provides a climate and environmentally friendly alternative to fossil fuels for supplying electricity and heat. However, in order to find sufficient temperatures and water at great depths using expensive boreholes, planners require detailed information in advance. This is where the GeotIS geothermal information system comes into play. The BINE-Projektinfo brochure “On the trail of deep geothermal energy” (09/2011) presents the system, which provides easy access to online data on geothermal potentials and sites in Germany.

IIn the form of a digital geothermal atlas, GeotIS provides interested parties such as planners, investors, local authorities and insurance companies with data for assessing sites for new geothermal projects. This information makes it easier to assess the exploration risk and thus determine the economic feasibility. In answering user queries, the system offers various interactive map formats, vertical and horizontal sections, tables and the ability to export data. The existing database covers regions that have already been used geothermally such as the North German Basin, the South German Molasse Basin in the Alpine Foreland and the Upper Rhine Graben. During the next few years, this information shall be supplemented with data on further regions and petrothermal geothermal energy, which uses the heat deposits in rock strata.

The Leibniz Institute for Applied Geophysics in Hanover coordinates and manages GeotIS. Further partners include the geological services of the various German federal states, Freie Universität Berlin and Geothermie Neubrandenburg GmbH. Wirtschaftsverband Erdöl- und Erdgasgewinnung (WEG) has also provided data for the first time from previous boreholes. The BINE Projektinfo brochure “On the trail of deep geothermal energy” (09/2011), which can be obtained free of charge from the BINE Information Service at FIZ Karlsruhe, is available online at or by calling +49 228 92379-0.
