Project: Flensburg, Germany

Project • Geothermal

Project • Seismic

Innargi and Stadtwerke Flensburg have agreed to investigate the potential for a geothermal district heating project in Flensburg. The aim of the agreement is to examine to what extent geothermal energy can further decarbonise district heating in Flensburg and thus contribute to the planned climate-neutral heat production of the district heating company in 2035.

In brief

  • The geothermal potential of the subsurface in Flensburg will be determined and evaluated within the next year.
  • If the test results are positive, there is nothing to prevent the construction and commissioning of a geothermal system

“At best, we can use geothermal energy to cover 25% of Flensburg’s district heating consumption. This would be a huge step towards climate neutrality, as geothermal energy is a suitable complement to our large-scale seawater pumps.”
