Denmark: Three Geothermal District Heating Networks Currently Operating

Increased focus on geothermal energy (Bruun & Hjejle)

Geothermal energy has long been used for district heating in Denmark, but lately political and industry interest therein has been on the rise. This has resulted in an increase in applications to explore for and produce geothermal energy. Since 2017, five new exploration licences have been granted and five additional licences are currently being assessed by the Danish Energy Agency (DEA).

Geothermal energy in Denmark can be used only for district heating and not to produce electricity, due to the low temperature of the saline water reservoirs in the Danish subsoil. Only three geothermal plants are in operation, but this may soon change. Geothermal energy will help to fulfil the political goal of a carbon-neutral Denmark by 2050.

At present, three geothermal plants are in operation, six additional licences for exploration and production of geothermal energy have been granted and applications for five additional areas are being assessed by the DEA. The current geothermal projects that have attracted the most interest are those in Aalborg and Aarhus.
