The People Who Perfected Fracking Are Now Using It to Unlock Unlimited Clean Energy

Fervo Energy's CEO Tim Latimer used to drill oil wells. Now he's using the exact same techniques — horizontal drilling, hydraulic fracturing, fibre-optic sensing — to tap Earth's heat instead of its fossil fuels. Three weeks ago, his team drilled their hottest well ever: 555°F at 11,200 feet deep, in under 11 days.

That well matters more than most people realise.

The oil industry's strangest pivot

Here's what makes Fervo unusual. Most clean energy companies are built by engineers who've never touched a drill rig. Latimer's first job out of college was drilling wells in the Eagle Ford Shale. He spent years perfecting the craft of punching holes into rock and pulling energy out.

"If it wasn't for climate change, I probably wouldn't have ever changed my career," he told Bloomberg.

He went to Stanford, got an MBA, met co-founder Jack Norbeck, and came back with a question: what if the same horizontal drilling that unlocked the shale revolution could unlock the heat sitting beneath every square metre of Earth?

Traditional geothermal needs natural hot springs. You find a spot where hot water already exists underground, and you tap it. That limits geothermal to volcanic regions — Iceland, parts of California, New Zealand. Only about 4 gigawatts of geothermal capacity exists in the US today.

Enhanced geothermal doesn't need natural reservoirs. It creates them. Drill two wells deep underground, first vertically then horizontally. Pump water at high pressure to fracture the rock. The water flows through the hot cracks, heats up, returns as steam. Electricity, 24 hours a day, zero emissions.

The US Department of Energy says there's at least 300 gigawatts of this sitting underground. We've tapped less than 1%.

The numbers that got Google's attention

Google became Fervo's first major customer in 2021, signing a 115-megawatt deal to power data centres in Nevada. The project went live in late 2023 — the world's first corporate-backed enhanced geothermal system delivering carbon-free electricity around the clock.

That "around the clock" part is the killer feature. Solar works when the sun shines. Wind works when it blows. Geothermal runs at up to 96% capacity factor. It's the only renewable that can match nuclear for reliability.

Google's AI data centres are desperate for 24/7 clean power. Solar and wind need massive battery banks to fill the gaps. Geothermal doesn't.

In December 2025, Fervo raised $462 million in an oversubscribed Series E round led by B Capital, the VC firm founded by Facebook co-founder Eduardo Saverin. The company's now preparing for an IPO, expected sometime in 2026-2027.

Cape Station: the project that proves it scales

Fervo's flagship is Cape Station in Beaver County, Utah. Phase I delivers 100 megawatts to the grid starting this year. Phase II adds another 400 megawatts by 2028. When complete, it'll be the world's largest next-generation geothermal project.

Then came Project Blanford.

On February 9, Fervo announced it had drilled a well at a new site in Millard County, Utah, hitting temperatures above 555°F at roughly 11,200 feet. They did it in fewer than 11 days. Hotter rock means more energy per well. Faster drilling means lower costs per megawatt.

The company calls Blanford a "giga-scale" site. Translation: they think there's enough heat under that patch of Utah to power a small country.

Why both sides of the aisle want this

Clean energy is partisan in America. Solar and wind trigger culture war reflexes. Nuclear takes decades to permit.

Geothermal is different. It uses oil and gas workers, oil and gas techniques, and oil and gas supply chains. Fervo is headquartered in Houston. Their drilling rigs look identical to the ones pulling crude out of the Permian Basin.

Republicans like it because it employs their voters and uses their industry's technology. Democrats like it because it's zero-emission baseload power. The DOE under both administrations has backed it, announcing $171.5 million to expand US geothermal capacity.

In a political environment where solar companies get targeted and wind farms get blocked, geothermal slides through because it looks and feels like oil and gas. The workers are the same. The skills are the same. The paychecks are the same. Only the output is different.

The catch nobody mentions

Enhanced geothermal isn't cheap yet. Drilling deep wells into hot rock costs millions per well. Fervo's technology works, but it hasn't proven it can compete with solar on cost — and solar is now the cheapest electricity source in human history.

The fracking comparison cuts both ways, too. Hydraulic fracturing underground raises the same questions it always does: induced seismicity (small earthquakes), water use, and community concerns. Fervo says their monitoring systems (fibre-optic sensors in every well) make it safer than conventional fracking. But "trust us, it's different this time" is a tough sell in communities that lived through the shale boom.

And there's a scale question. Fervo has one commercial project delivering power and another under construction. Solar added 55,809 megawatts to the US grid last year. Geothermal needs to go from science project to industrial rollout — fast.

The reason it matters anyway

Here's the thing about geothermal that gets lost in the solar-vs-wind debate: the energy transition needs baseload power. You can't run a hospital on sunshine. You can't power an aluminium smelter when the wind stops.

Right now, that baseload comes from natural gas (mostly) and nuclear (some). Both have problems — gas emits carbon, nuclear takes 15 years to build.

Geothermal is the only clean energy source that runs 24/7, can be built in years not decades, and works almost anywhere on Earth if you drill deep enough. The heat is always there. It doesn't depend on weather, latitude, or season.

The US is sitting on 300 gigawatts of it. An oil driller from Houston figured out how to get it. His company just drilled the hottest well it's ever seen, in 11 days, and is about to go public.

The tools that cracked the fossil fuel age might be the same ones that end it.
