Mazama Energy is a Frisco, Texas geothermal developer building Enhanced Geothermal Systems that tap superhot rock (SHR) - underground formations above 374 C - to deliver low-cost, round-the-clock, carbon-free electricity. Incubated by Khosla Ventures and backed by Gates Frontier, the company reached a world-record 629 F (331 C) bottomhole temperature at its Newberry Volcano pilot in Oregon and aims to produce power at under 5 cents per kWh, with 10x the power density, 75% less water, and 80% fewer wells than conventional geothermal.
Fervo Energy is a Houston-based next-generation geothermal company that borrows horizontal drilling and fiber-optic sensing from the oil and gas playbook to make enhanced geothermal systems (EGS) commercially viable. By drilling into hot dry rock almost anywhere - not just rare natural hotspots - Fervo produces around-the-clock, carbon-free firm power. Its flagship Cape Station project in Utah is on track to be the world's largest next-generation geothermal development, and the company has become a go-to supplier of clean baseload electricity for AI data centers and utilities.
Tim Latimer is the co-founder and CEO of Fervo Energy, the company that took horizontal drilling and fiber optic sensing out of the shale fields and pointed them straight down into hot rock. A former oil-and-gas drilling engineer who grew up next to the last coal plant built in America, he left the industry, talked his way into Stanford, met a geothermal PhD named Jack Norbeck, and bet that geothermal could become 24/7 carbon-free power at utility scale. Fervo has since raised over a billion dollars, broken drilling records once thought decades away, signed Google as a customer, and gone public on the Nasdaq in 2026 while building Cape Station, the world's largest next-generation geothermal project.
