Earth heating project in Wilhelmsburg: New delays by 2026!
The geothermal warproject in Hamburg-Wilhelmsburg, which was supposed to supply many households with sustainable energy, is stuttering. t-online.de reports that the commissioning of the facility has delayed again. The commercial thermal deliveries planned for spring 2025 should not take place until 2026. The original goal of supplying up to 6,000 households with geothermal energy is moving far away. The first bore that was carried out in 2021 already showed that the geological conditions are not optimal, because no sufficient occurrence could be obtained from a depth of 3,000 meters.
The delays are due to changed plans. Those responsible want to keep the option for a second geothermal mole open. In order to make room for these projects, the former drilling space in the port area is prepared, and fundamental work has been initiated for the construction of a heating house. Welt.de adds that had to revise the approval applications for the system, which the planning also pulls.
Details about the project
It is now planned to promote water from about 1,000 meters depth and to heat it to about 80 degrees using heat pumps. This is an amendment to the original concept, in which water should get up to 130 degrees hot. However, the efficiency of this system remains unclear because it will be operated with electricity in the future and the actual electricity consumption depends on various factors such as the ambient temperature and the mode of operation. [The website of German geothermal energy] (https://Deutsche-erdwaerme.de/) points out that the efficiency tested in the laboratory is 4.5 times the power consumption as heat energy.At the moment, the energy works in Wilhelmsburg are already supplying two decentralized heating networks, which together supply 157 buildings and around 3,700 residential units with heat. This is part of the larger project "Realabor Integrated Heat Wende Wilhelmsburg", which is funded by the Federal Ministry of Economics at 22.5 million euros. So far, however, there is no clear information on the total costs of the geothermal project.
increases in district heating prices
Another challenge is the increase in prices for district heating and hot water, which have risen by almost a third since May 1st. This fact could become an additional financial burden, especially in times of delay for the citizens in Wilhelmsburg. The hope of reliable and inexpensive heat supply through the geothermal heat project remains unbroken with many, while they are waiting for clear information for further development of the project.
