Innargi to deliver target geothermal heating capacity in Aarhus, Denmark with fewer plants
Instead of the planned seven plants, Innargi will only be putting up three geothermal heating plants in Aarhus, Denmark to reach the target heating capacity.
Geothermal developer Innargi has announced that it will now be delivering the target capacity of 110 MW of geothermal heating in the city of Aarhus in Denmark from only three locations, instead of the originally planned seven. The decision was based on the results of the three test wells that the company had started back in 2023.
Advancements in heat pump technology and local district heating company Kredsløb’s ongoing efforts to lower temperatures in the district heating grid also make it possible to consolidate the project into fewer plants. The plan is to now establish the heating facilities in Skejbyvej, Bautavej, and Halmstadgade, while the previously proposed plants in Brokvarteret, Bjørnholms Allé, Sumatravej, and Jens Juuls Vej are being excluded.
The heating plant in Skejby, which started construction in mid-2024, is expected to start supplying geothermal heat by the autumn of this year.
“Thorough analyses of all three test wells have shown that the northern part of Aarhus is the most suitable for geothermal energy from a subsurface perspective. Therefore, we have agreed with Kredsløb to place the geothermal plants in the northern part of the city,” said Sune Birk Kendrup, Project Director at Innargi.
Kendrup further added that a consequence of the new plan is that two additional wells will have to be drilled in the Skejby area. This is expected to commence by 2027.
Lasse Sørensen, Head of Business Development at Kredsløb, maintains that the plan is still for the whole system to be operational by 2029. At full capacity, the 110 MWth from geothermal will be enough to supply about 20% of the heat demand of Aarhus, thus replacing a substantial volume of wood pellets being burned to generate heat.
