Summary
Two weeks before the end of 2022, the local utility of Potsdam in Germany, Energie und Wasser Potsdam GmbH (EWP), announced the start of the deep geothermal project. A drilling rig had been deployed in Heinrich-Mann-Allee which will drill a well to a depth of around 1800 meters. Drilling of two boreholes is expected to continue until June 2023.
We had previously reported on the efforts of EWP to make the City of Potsdam climate-neutral, in line with the city’s goals of reducing carbon emissions by 95% by 2025. Starting late 2020, EWP in collaboration with the Potsdam Geo Research Center conducted seismic surveys to characterize the region’s subsurface geology and potential for hosting a geothermal resource.
The project developer expects to tap water at 65 to 70 degrees Celsius from a 200-million-year-old layer of red sandstone at 1800 meters depth. EWP expects that the two boreholes can supply the city’s district heating needs for around 50 years. However, there is still some uncertainty on the permeability of the targeted formation and the flowrate of water that can be produced from it.
