Project Kiel, Germany

Project • Seismic

Innargi and Stadtwerke Kiel have agreed to investigate the potential for a geothermal district heating project in Kiel. The purpose of the agreement is to further decarbonize district heating in order to ensure the planned climate neutral heat production of the district heating company in Kiel in 2035.

In brief

In Kiel, geothermal water with a temperature of up to 76 degrees will be extracted from a two-to-three-kilometres deep production well.
If the test results are positive, development of geothermal heating could start in 2025.

“This is another important step towards making our district heating carbon neutral. We want to investigate whether deep geothermal energy could be a building block in our energy transition program, ‘Kurs Klimaneutralität’, in the future.”
Dr. Jörg Teupen,
Chief of Technology and HR at Stadtwerke Kiel AG

Current status

We have been granted the geothermal exploration license for Kiel and the surrounding area by the State Office for Mining, Energy, and Geology, (LBEG Niedersachsen).

The license enables us to develop a geothermal project in or around the city. We expect the subsurface to be favorable for geothermal energy, which is why it could prove to be a stable and safe source of energy for the city of Kiel.

The permit is valid for five years and covers an area of just over 280 square kilometers. It includes the state capital, the Kiel Fjord, and adjacent areas between Strande in the north, Klein Barkau in the south, Melsdorf in the west, and Dobersdorf in the east.

The permit gives Innargi the right to conduct the exploration. However, actual exploration activities may only begin after approval of operating plans under the German mining law, which requires, among other things, a separate participation process.
