30% of Denmark’s district heating consumption can be provided by geothermal energy
Large-scale exploitation of geothermal energy is possible in areas where there are subsurface geothermal reservoirs as well as large contiguous district heating grids.
In Aalborg, it may be possible to cover 30-50% of district heating with geothermal energy. This would require approximately 10 geothermal plants with a total of 20 wells. Because geothermal heating would replace coal in Aalborg, the average household in Aalborg that switches to geothermal heating would have its CO2 footprint reduced by 1.5 tonnes a year.
We are currently in the project development phase. We have submitted an application to the Danish Energy Agency for a license to explore and extract geothermal energy in Aalborg. We are currently in dialogue with the local utility company Aalborg Forsyning about a potential heat supply agreement to provide heating to district heating customers in Aalborg. If both the license and heat supply agreement are endorsed, we will move on to the exploration phase.Learn more about the different phases in our business model
In Aarhus, it is possible to provide 30% of the district heating with geothermal energy. A full development would require ten geothermal plants with up to 22 wells. We have planned seven plants in Aarhus, covering up to 20% of the city’s district heating demand.
We are currently in the exploration phase. We have entered an agreement with Kredsløb (The district heating utility company for Aarhus Municipality) to develop and operate EU’s largest geothermal heating plant. The first exploration wells will be drilled 2023, and in 2025 the plant can start supplying the first geothermal district heating. The plant is expected to be completed in 2030 and operate in 30 years.Learn more about the different phases in our business model
