Geretsried, a town in southern Germany with a population of approximately 26,000, has intensified efforts to transition from fossil fuels to geothermal energy. Around 15 years ago, previous attempts to extract geothermal energy failed due to a lack of sufficient hot water near the surface. However, recent advancements in drilling technology, incorporating techniques from the oil and gas sector, have made deeper geothermal energy extraction more feasible. Eavor, a Canadian company, has established its first commercial geothermal power plant in Geretsried, positioning the town as a testing ground for this pioneering technology. The International Energy Agency (IEA) has acknowledged the potential of deeper drilling, which extends beyond 3 kilometers and allows geothermal energy to become a more viable source of power in multiple regions. This initiative aligns with Germany’s broader strategy to lower carbon emissions and enhance energy independence.

The project employs an innovative closed-loop system called the “Eavor Loop,” which consists of two wells drilled approximately 4 kilometers deep, with several lateral extensions to maximize heat extraction. Heated water circulates through hot rock, absorbing energy before resurfacing, eliminating the need for fracking. This system is expected to provide energy for around 36,000 homes. Additionally, steam generated from the process will facilitate electricity production with minimal environmental impact. The adoption of geothermal energy strengthens Germany’s energy resilience and supports long-term sustainability goals.
