This new project actually was built on the outskirts of an existing geothermal field where, in Terrell’s words, “there’s hot rock, but there’s no fluid.” To generate geoethermal energy there, Fervo had to drill two horizontal wells through which it pumps water. Fervo pushes cold water through fractures in the rock, which heats it up so it can generate steam back at the surface. It’s a closed-loop system, so the water gets reused — an important feature in a drought-prone region like Nevada.

Interesting they describe it as "closed loop", because that's assuming there is no or little loss downhole. Unlike Eavor, they have an open reservoir so you really need to understand the geology a lot more.
