Things are heating up at Houston-based geothermal power company Fervo Energy.

Fervo recently drilled its hottest well so far at a new geothermal site in western Utah. Fewer than 11 days of drilling more than 11,000 feet deep at Project Blanford showed temperatures above 555 degrees Fahrenheit, which exceeds requirements for commercial viability. Fervo used proprietary AI-driven analytics for the test.

Hotter geothermal reservoirs produce more energy and improve what’s known as energy conversion efficiency, which is the ratio of useful energy output to total energy input.

“Fervo’s exploration strategy has always been underpinned by the seamless integration of cutting-edge data acquisition and advanced analytics,” Jack Norbeck, Fervo’s co-founder and chief technology officer, said in a news release. “This latest ultra-high temperature discovery highlights our team’s ability to detect and develop EGS sweet spots using AI-enhanced geophysical techniques.”

Fervo says an independent review confirms the site’s multigigawatt potential.

The company has increasingly tapped into hotter and hotter geothermal reservoirs, going from 365 degrees at Project Red to 400 degrees at Cape Station and now more than 555 degrees at Blanford.

The new site expands Fervo’s geologic footprint. The Blanford reservoir consists of sedimentary formations such as sandstones, claystones and carbonates, which can be drilled more easily and cost-effectively than more commonly targeted granite formations.

Fervo ranks among the top-funded startups in the Houston area. Since its founding in 2017, the company has raised about $1.5 billion. In January, Fervo filed for an IPO that would value the company at $2 billion to $3 billion, according to Axios Pro.

Houston geothermal entrepreneur gears up 100x business growth

Geothermal energy has been growing in recognition as a major player in the clean energy mix, and while many might think of it as a new climatetech solution, Tim Latimer, co-founder and CEO of Fervo Energy, knows better.

"Every overnight success is a decade in the making, and I think Fervo, fortunately — and geothermal as a whole — has become much more high profile recently as people realize that it can be a tremendous solution to the challenges that our energy sector and climate are facing," he says on the Houston Innovators Podcast.

In fact, Latimer has been bullish on geothermal as a clean energy source since he quit his job as a drilling engineer in oil and gas to pursue a dual degree program — MBA and master's in earth sciences — at Stanford University. He had decided that, with the reluctance of incumbent energy companies to try new technologies, he was going to figure out how to start his own company. Through the Stanford program and Activate, a nonprofit hardtech program that funded two years of Fervo's research and development, Latimer did just that.

And the bet has more than paid off. Since officially launching in 2017, Fervo Energy has raised over $430 million — most recently collecting a $244 million series D round. Even more impressive to Latimer — his idea for drilling horizontal wells works. The company celebrated a successful pilot program last summer by achieving continuous carbon-free geothermal energy production with Project Red, a northern Nevada site made possible through a 2021 partnership with Google.

Next up for Fervo is growing and scaling at around a 100x pace. While Project Red included three wells, Project Cape, a Southwest Utah site, will include around 100 wells with significantly reduced drilling cost and an estimated 2026 delivery. Latimer says there are a dozen other projects like Project Cape that are in the works.

"It's a huge ramp up in our drilling, construction, and powerplant programs from our pilot project, but we've already had tremendous success there," Latimer says of Project Cape. "We think our technology has a really bright future."

While Latimer looks ahead to the rapid growth of Fervo Energy, he says it's all due to the foundation he put in place for the company, which has a culture built on the motto, "Build things that last."

“You’re not going to get somewhere that really changes the world by cutting corners and taking short steps. And, if you want to move the needle on something as complicated as the global energy system that has been built up over hundreds of years with trillions of dollars of capital invested in it – you’re not going to do it overnight," he says on the show. "We’re all in this for the long haul together."

Houston geothermal startup reports 'dramatic acceleration' of drilling operations at Utah project

optimization station

Early drilling results indicate a geothermal energy project operated in Utah by Houston-based startup Fervo Energy is performing better than expected.

Fervo says its drilling operations Utah’s Cape Station show a 70 percent reduction in drilling times, paving the way for advancement of its geothermal energy system. Fervo began construction last year on Cape Station, which is set to deliver clean power to the grid in 2026 and be fully operating by 2028.

The company recently published early drilling results from Cape Station that it says exceed the U.S. Department of Energy’s expectations for enhanced geothermal systems. Fervo says these results “substantiate the rapid learning underway in the geothermal industry and signal readiness for continued commercialization.”

Founded in 2017, Fervo provides carbon-free energy through development of next-generation geothermal power.

Fervo began drilling at Cape Station, a 400-megawatt project in southwest Utah, in June 2023. Over the past six months, the company has drilled one vertical well and six horizontal wells there. The company reports that costs for the first four horizontal wells at Cape Station fell from $9.4 million to $4.8 million per well.

“Since its inception, Fervo has looked to bring a manufacturing mentality to enhanced geothermal development, building a highly repeatable drilling process that allows for continuous improvement and, as a result, lower costs,” Tim Latimer, Fervo’s co-founder and CEO, says in a news release. “In just six months, we have proven that our technology solutions have led to a dramatic acceleration in forecasted drilling performance.”

Trey Lowe, chief technology officer of Oklahoma City-based oil and gas producer Devon Energy, likens Fervo’s drilling results to “the early days of the shale revolution.” Last year, Devon invested $10 million in Fervo.

“When you operate continually and understand the resource, you dramatically streamline operations. That’s the unique value of Fervo’s approach to enhanced geothermal,” says Lowe.

Last summer, Fervo reported the results of another one of its projects, Project Red, which is in northern Nevada and made possible through a 2021 partnership with Google. That site officially went online for the tech company in December.

Houston geothermal company's Google facility in Nevada goes online

up and running

Google is on a mission to run all of its data centers and office campuses on constant carbon-free energy by 2030, and the tech giant is one step closer to that goal.

Last week, Google announced that its 24/7 carbon-free energy, or CFE, in Nevada to power its local data center in the state is officially operational. The facility is powered by Houston-based Fervo Energy's geothermal technology, a project — called Project Red — that began in 2021 and celebrated its successful pilot this summer.

"When we began our partnership with Fervo, we knew that a first-of-a-kind project like this would require a wide range of technical and operational innovations," Michael Terrell, senior director of energy and climate at Google, writes in a blog post about the partnership.

Fervo relies on tried and true drilling techniques from the oil and gas industry, accessing heat energy that previously has been elusive to traditional geothermal methods, Terrell continues. Fervo dug two horizontal wells at the Nevada plant, as well as installed fiber-optic cables to capture data that tracks performance and other key information.

"The result is a geothermal plant that can produce round-the-clock CFE using less land than other clean energy sources and drawing on skills, knowledge, and supply chains that exist in other industries," Terrell says. "From our early commitment to support the project’s development to its successful completion, we’ve worked closely with Fervo to overcome obstacles and prove that this technology can work."

Google also recently announced a partnership with Project InnerSpace, a nonprofit focused on global geothermal energy development.

Fervo is working on another nearby project, the company announced in September. The 400-milliwatt geothermal energy project in Cape Station, Utah, will start delivering carbon-free power to the grid in 2026, with full-scale production beginning in 2028.

The project, in southwest Utah, is about 240 miles southwest of Salt Lake City and about 240 miles northeast of Las Vegas. Cape Station is adjacent to the U.S. Department of Energy’s Frontier Observatory for Research in Geothermal Energy (FORGE) and near the Blundell geothermal power plant.

Houston geothermal energy company announces major milestone

the results are in

A Houston energy startup has announced the news that every early-stage company wants to get to shout from the rooftops: the technology works.

Fervo Energy announced this week that its commercial pilot project has resulted in continuous carbon-free geothermal energy production. The full-scale commercial pilot, Project Red, is in northern Nevada and made possible through a 2021 partnership with Google.

“By applying drilling technology from the oil and gas industry, we have proven that we can produce 24/7 carbon-free energy resources in new geographies across the world," Tim Latimer, Fervo Energy CEO and co-founder, says in a news release. "The incredible results we share today are the product of many years of dedicated work and commitment from Fervo employees and industry partners, especially Google."

The goal of the partnership is to power Google’s Cloud region in Las Vegas with Fervo's geothermal-generated power.

“Achieving our goal of operating on 24/7 carbon-free energy will require new sources of firm, clean power to complement variable renewables like wind and solar,” adds Michael Terrell, senior director for energy and climate at Google. “We partnered with Fervo in 2021 because we see significant potential for their geothermal technology to unlock a critical source of 24/7 carbon-free energy at scale, and we are thrilled to see Fervo reach this important technical milestone.”

In honor of the announcement, today — July 19 — is the inaugural Fervo Energy Technology Day.

Fervo’s unique horizontal drilling technology has made an unprecedented accomplishment with Project Red, which has also proven the reliability and capacity of geothermal energy to supply over 20 percent of country's power needs, the company explains in its news release.

“Power systems modeling confirms that geothermal can be a critical player in a fully decarbonized grid," says Jesse Jenkins, assistant professor and leader of the Zero-carbon Energy systems Research and Optimization lab at Princeton University, in the release. "Fervo’s successful commercial pilot takes next-generation geothermal technology from the realm of models into the real world and starts us on a path to unlock geothermal’s full potential.”

Fervo has started work on its first greenfield development in southwest Utah, which is adjacent to the U.S. Department of Energy's Frontier Observatory for Research in Geothermal Energy (FORGE).

Last year, Fervo raised $138 million to further develop its technology. The series C round was led by California-based investment firm DCVC, with participation from six new investors. In April, Fervo Energy secured the $10 million strategic investment from Devon Energy Corporation (NYSE: DVN). The deal created a partnership between the two entities.

6 Houston companies earn recognition on Time’s global greentech list 2026

green giants

Six Houston-area businesses appear on Time magazine’s 2026 list of the world’s top greentech companies, with a high-flying name leading the pack.

The highest-ranked local company is Houston-based geothermal power producer Fervo Energy, which claims the No. 4 spot—up from No. 14 last year.

In May, Fervo raised nearly $1.9 billion in its IPO, making it the biggest-ever IPO in the clean energy sector. The company’s valuation now exceeds $10 billion.

Founded in 2017, Fervo borrows methods from the oil and gas sector to drill wells that go down vertically into hot rock before turning horizontal, letting water circulate through them and produce electricity from the heat it absorbs. Cape Station in Utah, the company's first utility-scale project, is set to start delivering power to the grid later this year, with capacity expected to grow to 100 megawatts by 2027.

Co-founder and CEO Tim Latimer tells Fast Company, which named him a 2026 Visionary of the Year, that he launched his career as a drilling engineer for fossil fuels, “but quickly became obsessed with this idea that the drilling techniques we were using would actually be transformative for the world of geothermal as well.”

Fast Company notes the geothermal power generated by Cape Station will be available 24/7, unlike wind and solar power.

“When you start adding something to the grid mix that’s affordable and works around the clock,” Latimer says, “that’s going to be a huge asset to meeting our country’s energy needs.”

Time teamed up with data provider Statista to compile the second annual ranking of the 250 top greentech companies in the world. Companies on the list either develop or provide green technology, products, or services that help ease or reverse the environmental impacts of human activity.

Statista gathered and analyzed data from more than 8,300 companies to create the list, and they were scored in three categories: positive environmental impact, innovation, and financial strength. Fervo earned a score of 94.63 out of 100.

Joining Fervo on this year’s list are:

Houston-based Quaise Energy (No. 78), which specializes in terawatt-scale geothermal power
The Woodlands-based Plus Power (No. 112), which develops, owns and operates battery storage projects
Houston-based Utility Global (No. 167), which develops decarbonization technology
Houston-based 1PointFive (No. 217), an Occidental Petroleum subsidiary that offers large-scale carbon removal and storage.
Houston-based Sage Geosystems (No. 250), which produces commercial-scale geothermal power

Earlier this year, six Houston-area companies landed on Time's list of top greentech companies in America: Fervo (No. 1), Quaise Energy (No. 49), Plus Power (No. 71), Utility Global (No. 98), Solugen (No. 199) and Noodoe (No. 215).

Houston-based Syzygy lands global customer for first commercial SAF plant

clean fuel deal

Houston-based Syzygy Plasmonics has secured a major future customer for its sustainable aviation fuel.

Syzygy announced this week that it has entered into a capacity reservation agreement with World Fuel Services, a global fuel distribution and logistics company.

Through the deal, World Fuel has reserved a portion of Syzygy's SAF production for future plants slated for Central and South America. The clean fuel will be produced at Syzygy’s NovaSAF-1 facility in Uruguay, which is moving toward construction.

The NovaSAF-1 will be the world's first electrified facility to convert biogas into sustainable aviation fuel (SAF). The facility is expected to produce over 350,000 gallons of SAF annually, which would be considered “a breakthrough in cost-effective, scalable clean fuel,” according to Syzygy.

The facility is expected to produce SAF with at least an 80 percent reduction in carbon intensity compared to Jet A fuel and make its first deliveries in 2028.

"Following NovaSAF-1, this agreement reflects continued interest in scalable pathways for producing SAF from biogas," Trevor Best, CEO of Syzygy Plasmonics, said in a news release. "Our NovaSAF platform is designed to deliver cost-competitive fuel while supporting the aviation sector's evolving regulatory and sustainability requirements."

Syzygy will make a portion of future production capacity available to World Fuel from its planned facilities, subject to the development and completion of those projects, according to the deal.

"We continue to evaluate supply opportunities that support increased access to lower carbon fuels in aviation, in line with emerging regulatory requirements and customer demand," Michael Ranger, senior vice president of supply EMEAA at World Fuel, added in the release. "Arrangements such as this are part of our ongoing efforts across the supply chain.”

Syzygy also secured an offtake agreement with Singapore-based commodity company Trafigura from NovaSAF-1 earlier this year.

Texas Gov. Abbott seeks data center crackdown as state grapples with growing power demand

growing pains

Just seven months ago, Gov. Greg Abbott trumpeted Google’s $40 billion plan to add three data center campuses in Texas. Now, amid growing public outcry over such projects, Abbott is pushing for a regulatory crackdown on data centers in the Lone Star State.

Abbott recently sent a letter to leaders of the Public Utility Commission of Texas (PUC) and the Electric Reliability Council of Texas (ERCOT) proposing stricter oversight of the state’s data centers. Texas is home to more than 400 data centers, with many more on the way, and is poised to become the world’s largest data center market.

Among other things, Abbott wants to:

Ensure residential electric bills go down — not up — as data centers connect to ERCOT’s grid, which supplies power for about 90 percent of Texans.
Require data centers to cover the costs of upgrades to deliver electricity to the power-hungry facilities.
Repeal sales tax exemptions and other “outdated or unnecessary” financial incentives for data centers.
Institute “best practices,” such as property setbacks and noise-reduction technology, to ease the impact of data centers on nearby residents.
Demand that all new data centers, which use a tremendous amount of water, be built with water-efficient technology.
Require large data centers to generate annual reports on their use of electricity and water.

Abbott has set a July 17 deadline for the PUC and ERCOT to address his recommendations.

“As Texas continues to welcome innovation and investment, we must ensure that growth strengthens our people and their quality of life without placing undue burdens on Texans and local communities,” Abbott wrote.

Abbott’s call for tighter control of data centers has elicited both praise and skepticism.

In a social media post on X, Texas House Speaker Dustin Burrows, a Lubbock Republican, thanked Abbott for seeking “accountability and reform” in the state’s data center industry. Burrows has made data centers one of his priority issues for the 2027 state legislative session.

State oil and gas regulator Wayne Christian, a member of the Texas Railroad Commission, weighed in with similarly positive comments about Abbott’s directive. He says an outright ban on data centers isn’t the answer to residents’ complaints about new facilities.

“The Texas way is not to answer innovation with government overreach or fear-driven bans,” Christian, whose agency wasn’t cited in Abbott’s letter, said in a statement posted on X. “Our job is to protect prosperity, safeguard taxpayers and ensure the infrastructure that powers our economy remains strong and reliable.”

Gina Hinojosa, an Austin Democrat who’s challenging Abbott in this November’s gubernatorial race, took issue with the governor’s edict on data centers.

“Greg Abbott is changing his tune on data centers because he knows his policies are unpopular,” Hinojosa, a state representative, wrote on X. “Nobody believes the arsonist is gonna be the one to put out the fire.”

Abbott’s call for stepped-up regulation of data centers echoes many of the concerns expressed by the state chapter of the Sierra Club, an environmental nonprofit.

“The growth of data centers reflects a broader transformation taking place across Texas,” the Sierra Club says on its website. “The state is becoming a hub for the technologies that will shape the future economy, from artificial intelligence to advanced computing and cloud services. At the same time, Texans deserve transparency about how these projects affect the communities where they are built.”
