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.

Texas City ammonia plant acquired by Yara in $1.3 billion deal

Ammonia Acquisition

Yara North America, a subsidiary of Norwegian fertilizer and ammonia producer Yara International, has agreed to buy an ammonia production plant in Texas City for $1.3 billion.

The seller is GCA Holdings, an affiliate of Texas City-based chemical manufacturer Gulf Coast Ammonia, which is owned by private equity firms Lotus Infrastructure Partners and MB Energy.

The Texas City plant, with an eventual annual capacity of 1.3 million metric tons, is expected to start full production by the end of this year. Yara says the ammonia produced by the plant will serve its own fertilizer production system and its key customers.

During a recent call with analysts and investors, Magnus Ankarstrand, executive vice president and CFO of Yara International, said the plant holds the potential to become one of the company’s most profitable plants. The $1.3 billion purchase price, he added, “is a very attractive entry ticket to ammonia production in the U.S. at a very attractive cost.”

The Texas City plant will add to Yara’s holdings in the Lone Star State, as Yara is the majority owner of an ammonia, hydrogen and nitrogen production plant in Freeport.

Construction of the ammonia plant began in 2020, but technical and infrastructure issues delayed the project. On its website, Gulf Coast Ammonia says the plant represented a $600 million investment.

“Gulf Coast Ammonia is a world-class asset that required disciplined execution across development, financing, construction, and commercial structuring,” Philipp Pletka, managing director of Lotus Infrastructure Partners, says in a news release.

Trexlertown, Pennsylvania-based Air Products, which owns and operates the country’s largest hydrogen pipeline network, will continue to supply hydrogen and nitrogen for the plant under a long-term deal with Yara, according to the release.

However, the news comes two days after Yara International announced that it would no longer be purchasing ammonia assets in the Louisiana Clean Energy Complex (LCEC) from Air Products. In a separate release, Yara said it planned to reallocate funds toward "alternative mature U.S. ammonia investment opportunities with more competitive returns."

Houston hypersonic engine company lands $91M to accelerate production

Clean Speed

Houston-based Venus Aerospace has closed a $91 million Series B round and plans to scale the production of its hypersonic engine.

The round was led by Houston-based Mercury Fund with participation from Lockheed Martin Ventures, MESH, PEAK6, Draper Associates, Starboard Star Venture Capital, Green Sands Equity and other investors, according to a news release.

The investment comes about a year after Venus completed the first U.S. flight test of its high-thrust rotating detonation rocket engine (RDRE). The engine is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus Aerospace says the latest round of funding will allow it to move the RDRE from demonstration to deployment and meet customer requirements for the near-term defense and space industries. The company says that the reusable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types.

“This financing marks an important step in moving Venus from breakthrough demonstration to scaled capability,” Sassie Duggleby, co-founder and CEO, said in the news release. “Our customers need propulsion systems that go farther, can be produced reliably and are built on supply chains they can trust. We are advancing that capability with American engineering and manufacturing talent to strengthen U.S. defense, expand space access and support the future of high-speed flight.”

Venus Aerospace raised a $20 million Series A in 2022, led by Wyoming-based Prime Movers Lab. At the time, the company said it would put the funding toward three main technologies: a next-generation rocket engine, aircraft shape and leading-edge cooling system.

The company also picked up an investment from Lockheed Martin Ventures, the investment arm of aerospace and defense contractor Lockheed Martin, in November 2025—in addition to funding from other investors over the years.

“Since our initial investment, Venus has progressed very quickly in its technology development," Chris Moran, vice president and general manager of Lockheed Martin Ventures, added in the release. "Our reinvestment in Venus recognizes Venus’ accomplishments to date and focus on speed to manufacture, cost management and reduction of supply chain constraints. Venus is working effectively to position its propulsion system for the production scale required by defense programs.”

"Venus is exactly the kind of company Houston capital should be backing," Blair Garrou, co-founder and managing partner at Mercury Fund, added in the release. "It combines multiple frontier technologies, domestic manufacturing and clear commercial and national security relevance. We believe this team is positioned to lead an important new chapter in defense and space, and we are proud to support a company building breakthrough technology here in Texas."

Venus Aerospace and Houston clean tech startup Vaulted Deep were also named to the World Economic Forum's Technology Pioneers community earlier this summer.
