Krefeld wants to use geothermal energy: geological hole starts behind town house!

In Krefeld, the Geological Service North Rhine-Westphalia began carrying out a test bore that focuses on researching the suitability for the use of geothermal energy. The hole, which takes place in the immediate vicinity of the Krefeld town house, will reach up to 1,000 meters. The project aims to analyze the deeper layers of rock and water in order to identify potential heat sources. The work is part of a nationwide initiative that provides for other similar holes in NRW in the coming years to promote the development of geothermal energy. [Welleniederrhein] reports that the project will take about eight weeks and will be carried out around the clock.

During the drilling work, rock and water samples are removed, which are then evaluated in the laboratory. The promising results should provide information about the possibility of using geothermal energy in Krefeld and the surrounding region for heating and electricity generation purposes. In these projects, the focus is on climate -friendly technologies that can ensure sustainable heat supply.

technical details of the hole

The Krefeld hole is special because it is one of the deepest of its kind in North Rhine-Westphalia. A comparable hole in Schwelm only reached a depth of 100 meters. The Krefeld subsoil could have a high level of relevance for the entire region. This is partly due to the fact that the rock in the underground on the Lower Rhine has similar properties that are crucial for geothermal generation. The aim is to penetrate the limestone sandstone layer to meet the sandstones underneath. [WDR] emphasizes that the project is accompanied by extensive geophysical measurements.

In order to protect the residents from noise pollution, special noise barriers were built with a height of ten meters. These protective measures are particularly important because the work takes place both during the day and at night. According to the project manager Ingo Schäfer, the desired results may be achieved after 700 to 800 meters, which could increase the efficiency of the project.

background of the initiative

The hole in Krefeld is part of the GEOTHERMIE NRW master plan, which strives to cover around 20 percent of the heat requirement in North Rhine-Westphalia by 2045. This form of energy generation has the advantage that it is always available regardless of climatic conditions and thus represents a basic load -bearing energy source. [GD NRW] indicates that the geothermal energy is increasingly considered an attractive energy alternative due to its independence of world market prices and low area consumption.

The development of geothermal energy by hydrothermal geothermal energy, which is possible from the depths of about 2 km, can reach water temperatures from 60 ° C to over 90 ° C. This makes the technology interesting for both heating and cooling inserts and electricity generation. The use of renewable energies in this sector is crucial to reduce greenhouse gas emissions and promote climate -friendly alternatives.
