Cologne-Dellbrück: 1000 meters deep for sustainable geothermal energy!
From the end of 2023, the state of North Rhine-Westphalia (NRW) in Cologne-Dellbrück is planning a comprehensive research hole to a depth of 1000 meters. This was confirmed by the Cologne city administration and the Ministry of Economic Affairs and Climate Protection of North Rhine-Westphalia (MWIKE). This measure is part of the "exploration and drilling program", which was launched as part of the Geothermia NRW master plan.
The main goal of the master plan is to cover up to 20 percent of the heat requirement in NRW by geothermal energy by 2045. The location for the hole was carefully selected: a former sports field on Thurner Kamp, which is currently unused. This place was originally supposed to be converted into an ecological compensation area, as the district council of Mülheim 2022 decided. In addition, SV Adler Dellbrück has registered the area to fix the lack of space of the association.
Details about the drilling work
The drilling work is expected to begin at the end of 2025 and take a period of about a year. During this time it is expected that important knowledge about the limestone layer will be gained at 600 to 1000 meters. This layer could potentially be suitable for the use of geothermal energy. To protect residents, noise barriers and a noise “are installed. After completing the holes, a restoration of the area is planned, but a complete repair as a natural lawn area is not guaranteed.
So far, two flatter holes in Düsseldorf and Schwelm have already been carried out as part of the program. Another bore in Krefeld is currently underway. The results of these measures are published in the Geothermieportal NRW, which provides comprehensive information on the geological nature of the underground. The portal is a central point of contact for geographical suitability for various geothermal projects and includes over 10,000 geological layer lists.advantages of geothermal energy
geothermal energy is considered a climate -friendly and regenerative heat source, which is available regardless of weather conditions and requires little space for high energy production. These are some of the advantages that the GEOTHERMIE NRW master plan emphasizes. In April 2024, Minister Mona Neubaur presented the intention to open up between 24 and 33 terrawatt hours annually by using geothermal energy. In order to achieve these goals, extensive exploration measures are necessary, since the deep geological structures in NRW have so far been insufficiently known.
The state government has commissioned the geological service of North Rhine -Westphalia with intensive investigations to create a solid planning basis for municipalities, industry and project developers. This justifies the need to explore suitable rock formations in order to be able to use the heat efficiently. A central challenge remains the implementation of detailed on-site examinations, which should ideally be implemented by specialized specialist companies.
In summary, it can be said that the planned bore in Cologne-Dellbrück represents a further step in the sustainable heat supply of North Rhine-Westphalia, which could significantly influence the long-term energy supply of the region. Trained specialists and modern technologies are needed to optimally develop the potential of geothermal energy.| Details | |
