Green Therma and Aalborg Forsyning have found the location for a new geothermal demonstration plant that will test a new method for utilizing the earth's heat in the district heating network. The plant will be located on a commercial property in Storvorde and marks the next phase in the work of developing geothermal solutions for large-scale district heating. This is written by Aalborg Forsyning.
- We have now found the perfect location for the demonstration plant on a commercial property in Storvorde. The location here is optimal, among other things, due to favorable geological conditions and because of the proximity to the existing district heating network, says Mads Sylvest Eegholm, project manager at Green Therma.
The project will document and test Green Therma's in-house developed technology, which is expected to be able to deliver around 17,520 MWh of heat per year - equivalent to the heat consumption of more than 900 households. Aalborg Forsyning has entered into a 30-year agreement to purchase heat from the plant, while Green Therma is responsible for financing, establishment and operation with support from EUDP.
- Aalborg Forsyning is participating in the project based on a desire to actively contribute to the testing, development and maturation of future district heating technologies. The plant represents a very small part of our total district heating production, but the primary purpose of the project is to test the solution and investigate whether geothermal energy can be included in the district heating production of the future,” says Mathias Tjell Brassøe, Business Development Manager at Aalborg Forsyning.
The next step will be to obtain a building permit and conduct an EIA screening. In addition, Green Therma and Aalborg Forsyning are planning a citizens' meeting to inform about the project and the upcoming construction phase.
The first seismic surveys will be carried out by GEUS in early 2026 to map the subsoil and determine the exact location of the drilling site. The drilling itself is expected to begin in the fall of 2026. When the plant is completed, it is expected to be able to deliver stable and sustainable heat for more than 50 years.
