Hot on the heels of the successful completion of its grid-connected geothermal power plant in Nevada, Fervo Energy is raising $221 million per SEC documents, TechCrunch has exclusively learned. Previous geothermal plants have only scratched the surface by accessing hot springs or shallower rock formations. Fervo uses directional drilling techniques pioneered by the oil and gas industry to extend its wells far beyond their surface footprints. Once those wells are drilled, Fervo then strings them with fiber optic cables connected to a range of sensors. Previous investors include BHP Ventures, Breakthrough Energy Ventures, Congruent Ventures, DCVC, and Prelude Ventures.
