Google Backs Fervo Energy's $462M Geothermal Push

Fervo Energy, a leading startup in enhanced geothermal technology, has successfully closed a $462 million Series E funding round. This significant investment, which includes participation from tech giant Google, will fuel the company's efforts to complete its inaugural large-scale power plant and commence development on several new sites, aiming to supply much-needed electricity to a rapidly growing grid, particularly for energy-intensive data centers.

The fresh capital infusion will enable Fervo to continue construction on its 500-megawatt Cape Station power plant in Utah while simultaneously initiating development for other projects, as confirmed by Sara Jewett, Fervo's Senior Vice President of Strategy, to TechCrunch.

The Series E round was spearheaded by B Capital, with a broad consortium of investors joining, including AllianceBernstein, Atacama Ventures, Breakthrough Energy Ventures, CalSTRS, Capricorn Investment Group, Carbon Equity, Centaurus Capital, Climate First, Congruent Ventures, CPP Investments, Devon Energy, Echelon, Galvanize, Google, Impact Science Ventures, Kris Singh, JB Straubel, Liberty Mutual Investments, Marunouchi Innovation Partners, Mercuria, Mitsubishi Heavy Industries, Mitsui and Co., and Sabanci Climate Ventures.

Google's involvement extends beyond this investment; the company already has an existing agreement with Fervo to power its data centers with geothermal electricity.

Progress at Cape Station and Geothermal's Ascent

Fervo aims to bring the first phase of its Cape Station online by 2026, with Jewett confirming that the plant is on track to be "mechanically complete" this year. “It’s very real and very tangible,” she stated.

This latest funding follows a $206 million financing package announced just six months prior, which included loans and project-level preferred equity specifically for Cape Station. Last year alone, Fervo secured nearly $500 million in combined equity and debt.

Enhanced geothermal technology, though under development for years, has recently seen a surge in interest and prospects due to favorable market conditions.

Powering the Future: Data Centers and Geothermal

A primary driver for this renewed interest is the skyrocketing demand from data centers. Major tech companies, including Google and Meta, are actively exploring geothermal energy as a sustainable solution for their substantial energy requirements. An analysis by the Rhodium Group earlier this year projected that by 2030, enhanced geothermal could potentially supply nearly two-thirds of new data center demand at competitive costs.

Geothermal energy also enjoys political favor, notably within the current administration. Energy Secretary Chris Wright, for instance, previously invested in Fervo through his company, Liberty Energy, participating in a $138 million round Fervo raised in 2022. Fervo, like many of its industry peers, employs fracking and directional drilling techniques adapted from the oil and gas sector. Many of Fervo's employees bring their expertise from the oil and gas industry, applying their knowledge of drilling and subsurface development to this new challenge.

Fervo is recognized as a frontrunner among enhanced geothermal startups, distinguishing itself by drilling deeper than conventional geothermal developers to access hotter rock formations and generate greater power output.

Efficiency and Expansion: Fervo's Strategic Approach

The company's expertise has significantly reduced the time required to drill new wells. While Fervo's initial wells took approximately a month, the company announced this summer that it completed one in just 16 days. “We are in the mid-teens these days, on average, for our well drilling times,” Jewett noted, adding, “That is pretty good, but we always have more improvements to make.”

Fervo's focus on optimizing drilling time is both an economic imperative and a source of pride. Jewett explained, “Roughly half the cost of wells is in the drilling time.” Shorter drilling periods translate to faster power plant completion and quicker revenue generation. They also signify a mastery of the technology. “It’s also a good representation of how much you’re investing in the well, how much you’re troubleshooting, how many issues are plaguing you that end up costing money,” she elaborated.

Currently, Fervo's operations are concentrated in the Western U.S., where hot rock formations are closer to the surface. At its Cape Station site in Utah, for example, Fervo drills down 8,500 feet to tap into 450°F rock.

Jewett indicated that expansion to other regions, including internationally, will occur only after the company has fully optimized its drilling efficiency in the West. “If you go to Pennsylvania or West Virginia, [the hot rock] exists much lower,” she said. Despite geographical variations within the U.S., the diverse rock types offer Fervo ample opportunity to accumulate technical experience before venturing abroad, where regulatory differences are expected to be the primary hurdle.

Given the escalating energy demands from data centers and Fervo's rapid progress at Cape Station, there have been rumors of a potential IPO within the next year or so. While Jewett refrained from commenting on these speculations, she affirmed that the company is experiencing “off-the-charts demand.”
