The technical and economic feasibility of developing a geothermal resource in the cities of Düsseldorf and Duisburg in North Rhine-Westphalia (NRW), Germany is being analyzed under the “Geothermie-Rhein” inter-municipal project. This project stems from a resolution passed by the state parliament in March 2019 to promote the heat transition by developing geothermal energy.
The joint feasibility study is being undertaken by the respective municipal utilities, Stadtwerke Düsseldorf AG and Stadtwerke Duisburg AG, along with Fraunhofer IEG, the University of Duisburg-Essen, and the Düsseldorf Airport.

Part of the study also analyzes the economics of the expansion of the district heating network. Stadtwerke Duisburg, together with the chair for energy technology at the University of Duisburg-Essen, is analyzing the details of the economics and technology of the local energy systems.
