About
Fervo Energy is an enhanced geothermal systems (EGS) company founded to unlock the vast heat energy stored in the Earth's crust at locations that conventional geothermal technology cannot reach. Traditional geothermal power requires naturally occurring hydrothermal reservoirs that are geographically rare; Fervo's EGS technology drills horizontal wells and hydraulically fractures hot dry rock to create engineered reservoirs anywhere there is sufficient heat at depth. This breakthrough — borrowed from the oil and gas industry's directional drilling playbook — transforms geothermal from a niche resource into a potentially ubiquitous baseload clean energy source.\n\nFervo's flagship project, Cape Station in Utah, is the world's largest EGS facility and is on track to deliver 100 megawatts of firm, 24/7 clean power in 2026, scaling to 500 megawatts by 2028. Unlike solar and wind, geothermal power is dispatchable and not weather-dependent, making it the rare clean energy technology that can provide carbon-free baseload power to complement intermittent renewables. Google signed a power purchase agreement with Fervo, making it one of the first large technology companies to source EGS-generated electricity for its data centers — a landmark commercial validation for the technology.\n\nFervo Energy raised $462 million in a Series E round in December 2025 led by B Capital Group with participation from Google, bringing its total funding to approximately $1.5 billion. The company is positioned at the center of the clean energy transition's firm power problem — the challenge of decarbonizing the grid when renewables are not generating. With proven technology, a major commercial customer in Google, and a clear megawatt delivery roadmap, Fervo is the most advanced EGS company globally and a critical infrastructure bet for the deep decarbonization of electricity.
