Eavor’s project in Geretsried was featured in a detailed Anthropocene Magazine article as a prime example of the “new generation of geothermal anywhere efforts.”
The project exemplifies modern innovation that harnesses heat radiating from the Earth’s 5,000°C molten core. Since the average temperature rises 30°C every kilometre drilled into the earth, this energy can be accessed virtually anywhere across the globe via geothermal technologies.
According to the article, the key to making geothermal energy economically feasible lies in drilling depth and speed. Eavor has demonstrated that its patented technology can operate in extreme conditions where traditional oil and gas technology fails, drilling up to 5,500 meters where temperatures approach 250°C.
In Geretsried, Eavor is drilling two 4,500-meter-deep wells into the granite subsurface, connecting a system of wellbores to function like radiator coils. This system circulates water that is naturally heated by the Earth’s energy, reaching temperatures of up to 160°C. The heated water is then pumped to the surface to generate heat and electricity for the surrounding region.
Eavor CEO John Redfern emphasizes the importance of district heating in Europe, particularly in countries like Germany, where extensive heating networks are already established. Furthermore, Redfern explains that Eavor’s design not only scales geothermal, but it’s vastly more appealing in countries that are strongly opposed to fracking.
Decarbonizing heating systems is a crucial step in reducing global emissions, which is why European officials are anticipating that capital costs will be curbed as more geothermal projects are developed. Providing a reliable and sustainable energy supply is essential for meeting climate goals, ensuring energy security and transitioning away from fossil fuels.
