Geothermal energy is becoming "advanced" and earthquake safe with Eavor!

Another company has taken an even more risk-averse approach. Eavor, based in Calgary, Canada, calls its geothermal technology ‘advanced’ rather than ‘enhanced’, and foregoes fracking altogether. Instead, the company has developed a sophisticated magnetic guidance system, in which the drill heads from the two boreholes guide each other and form closed loops underground. “There’s no GPS when you are four and a half kilometres underground,” says Matt Toews, the company’s chief technology officer. In an Eavor project, each borehole branches out into a grid of parallel, horizontal pipes, which then reconnect at the other borehole. This also means that the water never comes into direct contact with the rock, but has to absorb heat through the pipes’ casings. “The advantage is that we don’t have to frack,” says Carsten Reinhold, chief geologist at Eavor’s German arm in Düsseldorf. Eavor is building its first commercial geothermal plant near Geretsried, Germany, and this should start exploiting 160 °C water from a depth of 4,500 m next year. The plant will mostly provide heating to buildings in the nearby town, but will also generate about 8 MW of electricity. here is a link to the story! https://www.nature.com/articles/d41586-024-03621-w
