Summary

A 2D seismic survey has been completed in the city of Hanover in Lower Saxony, Germany, mapping out the subsurface to provide the basis for a novel, closed-loop geothermal system that will provide heating to the city. The survey was led by Eavor GmbH, which is executing this project with partner enercity.

Initiated in 2023 with a contract signing between the two project partners, the Hanover geothermal project envisions a 2 x 15 MW facility that will supply up to 250 million kWh of heat for 20,000 homes in the enercity supply area. This will replace part of the heat supply that is currently sourced from a coal-fired plant in Hannover-Stöcken that is due for shut down possibly by 2026 but no later than 2030.

A critical component of the project is Eavor’s signature Eavor-Loop technology, which harnesses geothermal energy without the prerequisite natural permeability or in-situ reservoir fluids.
