Houston-based Fervo Energy has received yet another accolade—MIT Technology Review named the geothermal energy startup to its 2025 list of the 10 global climatetech companies to watch.

Fervo, making its second appearance on the third annual list, harnesses heat from deep below the ground to generate clean geothermal energy, MIT Technology Review noted. Fervo is one of four U.S. companies to land on the list.

Fervo “uses fracking techniques to create geothermal reservoirs capable of delivering enough electricity to power massive data centers and hundreds of thousands of homes,” MIT Technology Review said.

MIT Technology Review said it produces the annual list to draw attention to promising climatetech companies that are working to decarbonize major sectors of the economy.

“Though the political and funding landscape has shifted dramatically in the US since the last time we put out this list,” MIT Technology Review added, “nothing has altered the urgency of the climate dangers the world now faces — we need to rapidly curb greenhouse gas emissions to avoid the most catastrophic impacts of climate change.”

In addition to MIT Technology Review’s companies-to-watch list, Fervo has appeared on similar lists published by Inc.com, Time magazine and Climate Insider.

In an essay accompanying MIT Technology Review’s list, Microsoft billionaire Bill Gates said his Breakthrough Energy Ventures investment group has invested in more than 150 companies, including Fervo and another company on the MIT Technology Review list, Redwood Materials.

In his essay, Gates wrote that ingenuity is the best weapon against climate change.

Yet climate technology innovations “offer more than just a public good,” he said. “They will remake virtually every aspect of the world’s economy in the coming years, transforming energy markets, manufacturing, transportation, and many types of industry and food production. Some of these efforts will require long-term commitments, but it’s important that we act now. And what’s more, it’s already clear where the opportunities lie.”

In a recent blog post highlighting Fervo, Gates predicted geothermal will eventually supply up to 20 percent of the world’s electricity, up from his previous estimate of as much as 5 percent.

Fervo is one of the pioneers in geothermal energy. Gates and other investors have pumped $982 million into Fervo since its founding in 2017. With an estimated valuation of $1.4 billion, Fervo has achieved unicorn status, meaning its valuation as a private company exceeds $1 billion.

Aside from Breakthrough Energy Ventures, oilfield services provider Liberty Energy is a Fervo investor. U.S. Energy Secretary Chris Wright was chairman and CEO of Denver-based Liberty Energy before assuming his federal post.

Axios reported on Oct. 1 that Fervo is raising a $300 million series E round, which would drive up the startup’s valuation. News of the $300 million round comes as the company gears up for a possible IPO, according to Axios.

Fervo co-founder and CEO Tim Latimer told Axios this spring that a potential IPO is likely in 2026 or 2027. Ahead of an IPO, the startup is aiming for a $2 billion to $4 billion valuation, Axios reported.

The first phase of Fervo’s marquee Cape Station geothermal energy plant in Utah is scheduled to go online next year, with the second phase set to open in 2028. Once it’s completed, the plant will be capable of generating 500 megawatts of power. This summer, the startup said it secured $205.6 million in capital to finance construction of the plant.

Houston energy SPAC goes public through IPO

blank check

Houston-based CO2 Energy Transition Corp. — a “blank check” company initially targeting the carbon capture, utilization, and storage (CCUS) sector — closed November 22 on its IPO, selling 6 million units at $10 apiece.

“Blank check” companies are formally known as special purpose acquisition companies (SPACs). A SPAC aims to complete a merger, acquisition, share exchange, share purchase, reorganization or similar business combination in certain business sectors. CO2 Energy Transition will target companies valued at $150 million to $250 million.

Each CO2 Energy Transition unit consists of one share of common stock, one warrant to purchase one share of common stock at a per-share price of $11.50, and the right to receive one-eighth of a share of common stock based on certain business conditions being met.

The IPO also included the full exercise of the underwriter’s option to buy 900,000 units to cover over-allotments. Kingswood Capital Partners LLC was the sole underwriter.

Gross proceeds from the IPO totaled $69 million. The money will enable the company to pursue CCUS opportunities.

“Recent bipartisan support for carbon capture legislation heavily emphasized the government’s willingness to advance and support technologies for carbon capture, utilization, storage, and other purposes as efforts to reduce greenhouse gas emissions [continue],” Co2 Energy Transition says in an October 2024 filing with the U.S. Securities and Exchange Commission (SEC).

Brady Rogers is president and CEO of CO2 Energy Transition. He also is CEO of Carbon Capture Development Co., a Los Angeles-based developer of direct air capture (DAC) technology, and president of Houston-based Antelope Energy Partners LLC, a provider of oil and gas services.

Former Houston energy services CEO's SPAC announces $700M merger with energy transition materials company

M&A moves

Houston-based Pyrophyte Acquisition Corp., a “blank check” SPAC, plans to merge with Canadian quartz silica producer Sio Silica Corp. in a deal valued at more than $700 million.

The companies say the deal carries an enterprise value of $708 million and an equity value of $758 million.

Sio is sitting on a potential supply of 15.2 billion metric tons of high-purity quartz silica, a material needed to produce energy transition technologies such as photovoltaics, solar panels, semiconductors, batteries, and other electronics. Proceeds from the merger will be earmarked for construction of the first phase of Sio’s silica extraction and processing facility near Winnipeg, Manitoba.

“We searched long and hard for the right candidate to combine with Pyrophyte and its energy transition mission. Sio fulfilled all our criteria,” Bernard Duroc-Danner, chairman of Pyrophyte, says in a news release. “We are proud to join Sio on its journey to supply what is becoming in many countries around the world one of the most important strategic minerals for the world’s energy transition.”

In 2021, Pyrophyte’s stock began trading on the New York Stock Exchange in an IPO valued at $201.25 million. Since then, it’s solely been a special purpose acquisition company (SPAC) without any business operations. Typically, a SPAC aims to acquire or merge with a private company that boasts a promising business model.

Duroc-Danner is former chairman, president, and CEO of Houston-based oilfield equipment and services company Weatherford International Ltd.

Calgary, Alberta-based Sio says high-purity quartz silica will represent a $30 billion global market opportunity by 2030. Among the products that rely on silica are semiconductors, solar panels, photovoltaic (solar) cells, optical fibers, and batteries.

Once the deal closes, the combined company will operate as Sio Silica Inc., whose stock will be traded on the New York Stock Exchange. Sio’s CEO, Feisal Somji, will lead the newly formed company.

The deal has been approved by Sio’s and Pyrophyte’s boards but still must be endorsed by the companies’ shareholders.

Q&A: Houston robotics entrepreneur on IPO, military innovation, and more

automation nation

Almost a decade ago, Nicolaus Radford founded a robotics company that automated underwater operations for heavy industry customers. Now, the company provides its robotics-as-a-service business to customers across industry, providing key analytics, risk-managed monitoring, and emission-reducing service.

Nauticus Robotics (Nasdaq: KITT) went public via SPAC last year, and Radford, CEO and founder, sat down with InnovationMap earlier this year to share the unique challenges he faced with the IPO, the company's partnerships with the United States Marine Corps, and more. Check out the shortened Q&A below and head to InnovationMap for the full conversation.

InnovationMap: Tell me about life after IPO. What’s been surprising for you leading your company through the transition and now on the other side of IPO?

Nicolaus Radford: I'll tell you what, it’s the hardest thing I ever did in my professional career by a factor of 10. It was a very exceptionally challenging period of time. It took a long to complete the transaction, and the market was just changing under our feet. Rules were and regulations were changing — were we grandfathered in or were we not?

I'm part of some business organizations and, and some of those confidential relationships have turned into friendships. And a couple of them call me and they're like, “we're really worried. We think this is going to be we don't know if you're going to get it done. And we just want you to be aware that you're not you may not get it done.” It is a little scary because once you engage in it, you're running quite a tab with bankers and law firms and all sorts of things. And if you don't complete the deal, it just might kill the company.

But we did it. We were one of a few people last year to actually get a deal over the line. I'm very proud of that. I think it speaks to the quality of the deal that we had. The macro economic environment was exceptionally difficult. It remains to be very difficult today. But we had strong backing from our strategic investors and our partners that were already on the cap table. They put a tremendous amount of money into the deal.

You know, I look back on it and it's, you know, ringing the Nasdaq bell when we listed, and giving that speech at the podium — it was a surreal moment. I remember when I was standing there looking at the Nauticus logo on the seven-story Nasdaq tower, having as many people in the company as we could bring, and just sharing that moment with all of them.

I was excited but cautious at the same time. I mean, the life of a CEO of a public company at large, it's all about the process following a process, the regulations, the administration of the public company, the filings, the reportings — it can feel daunting. I have to rise to the occasion to tackle that in this the next stage of the company.

IM: You’re working with the military on a project that adapts Nauticus tech for Marine Corps use. What’s it been like working with the military on this project?

NR: We've probably worked with military interests for the last six years, but all of the things that we have been doing have been extremely confidential and hush. Now we've been able to work with customers that have a stronger public facing persona, and the Defense Innovation Unit is one of those.

Their charter is it's quite literally looking for commercial technology and adapting that towards military applications, and so it's been nice to be able to show the utility and the application of of a lot of our technology and what we've been working on for so long as it's applied on a broader scale to the big services, whether it's the Navy or the Marine Corps.

Both of the programs we’re working on are all about mine countermeasures, and mines are really, really difficult, especially underwater mines. We've been we've been applying all of Nauticus’s broad technology portfolio to being able to search autonomously and being able to identify and neutralize threats in the water. I love that mission because anytime we can remove our service men and women from these situations, that's just the right thing to do.

IM: What’s next for Nauticus?

NR: What’s next is tough to talk about, because I can only talk about what’s already been published. I see Nauticus being the preeminent ocean robotics company. I want Nauticus to be an empire. It starts small but it grows — and it grows in many different ways, and we’re exploring all of those different ways to grow. We’re leading a technology renaissance in the marine space — and that happens only a few times in an industry.

Federal judge strikes Trump order blocking wind energy development

wind win

In a win for clean energy and wind projects in Texas and throughout the U.S., a federal judge struck down President Donald Trump’s “Day One” executive order that blocked wind energy development on federal lands and waters, the Associated Press reports.

Judge Patti Saris of the U.S. District Court for the District of Massachusetts vacated Trump’s executive order from Jan. 20, declaring it unlawful and calling it “arbitrary and capricious.”

The challenge was led by a group of state attorneys general from 17 states and Washington, D.C., which was led by New York Attorney General Letitia James. The coalition pushed back against Trump's order , arguing that the administration didn’t have the authority to halt project permitting, and that efforts would critically impact state economies, the energy industry, public health and climate relief efforts.

White House spokesperson Taylor Rogers told the Associated Press that wind projects were given unfair treatment during the Biden Administration and cited that the rest of the energy industry suffered from regulations.

According to the American Clean Power Association, wind is the largest source of renewable energy in the U.S. It provides 10 percent of the electricity generated—and growing. Texas leads the nation in wind electricity generation, accounting for 28 percent of the U.S. total in 2024, according to the U.S. Energy Information Administration.

Several clean-energy initiatives have been disrupted by recent policy changes, impacting Houston projects.

The Biden era Inflation Reduction Act’s 10-year hydrogen incentive was shortened under Trump’s One Big Beautiful Bill Act, prompting ExxonMobil to pause its Baytown low-carbon hydrogen project. That project — and two others in the Houston region — also lost federal support as part of a broader $700 million cancellation tied to DOE cuts.

Meanwhile, Texas House Democrats have urged the administration to restore a $250 million Solar for All grant that would have helped low-income households install solar panels.

Texas launches cryptocurrency reserve with $5 million Bitcoin purchase

Digital Deals

Texas has launched its new cryptocurrency reserve with a $5 million purchase of Bitcoin as the state continues to embrace the volatile and controversial digital currency.

The Texas Comptroller’s Office confirmed the purchase was made last month as a “placeholder investment” while the office works to contract with a cryptocurrency bank to manage its portfolio.

The purchase is one of the first of its kind by a state government, made during a year where the price of Bitcoin has exploded amid the embrace of the digital currency by President Donald Trump’s administration and the rapid expansion of crypto mines in Texas.

“The Texas Legislature passed a bold mandate to create the nation’s first Strategic Bitcoin Reserve,” acting Comptroller Kelly Hancock wrote in a statement. “Our goal for implementation is simple: build a secure reserve that strengthens the state’s balance sheet. Texas is leading the way once again, and we’re proud to do it.”

The purchase represents half of the $10 million the Legislature appropriated for the strategic reserve during this year’s legislative session, but just a sliver of the state’s $338 billion budget.

However, the purchase is still significant, making Texas the first state to fund a strategic cryptocurrency reserve. Arizona and New Hampshire have also passed laws to create similar strategic funds but have not yet purchased cryptocurrency.

Wisconsin and Michigan made pension fund investments in cryptocurrency last year.

The Comptroller’s office purchased the Bitcoin the morning of Nov. 20 when the price of a single bitcoin was $91,336, according to the Comptroller’s office. As of Friday afternoon, Bitcoin was worth slightly less than the price Texas paid, trading for $89,406.

University of Houston energy economist Ed Hirs questioned the state’s investment, pointing to Bitcoin’s volatility. That makes it a bad investment of taxpayer dollars when compared to more common investments in the stock and bond markets, he said.

“The ordinary mix [in investing] is one that goes away from volatility,” Hirs said. “The goal is to not lose to the market. Once the public decides this really has no intrinsic value, then it will be over, and taxpayers will be left holding the bag.”

The price of Bitcoin is down significantly from an all-time high of $126,080 in early October.

Lee Bratcher, president of the Texas Blockchain Council, argued the state is making a good investment because the price of Bitcoin has trended upward ever since it first launched in early 2009.

“It’s only a 16-year-old asset, so the volatility, both in the up and down direction, will smooth out over time,” Bratcher said. “We still want it to retain some of those volatility characteristics because that’s how we could see those upward moves that will benefit the state’s finances in the future.”

Bratcher said the timing of the state’s investment was shrewd because he believes it is unlikely to be valued this low again.

The investment comes at a time that the crypto industry has found a home in Texas.

Rural counties have become magnets for crypto mines ever since China banned crypto mining in 2021 and Gov. Greg Abbott declared “Texas is open for crypto business” in a post on social media.

The state is home to at least 27 Bitcoin facilities, according to the Texas Blockchain Council, making it the world’s top crypto mining spot. The two largest crypto mining facilities in the world call Texas home.

The industry has also come under criticism as it expands.

Critics point to the industry’s significant energy usage, with crypto mines in the state consuming 2,717 megawatts of power in 2023, according to the comptroller’s office. That is enough electricity to power roughly 680,000 homes.

Crypto mines use large amounts of electricity to run computers that run constantly to produce cryptocurrencies, which are decentralized digital currencies used as alternatives to government-backed traditional currencies.

A 2023 study by energy research and consulting firm Wood Mackenzie commissioned by The New York Times found that Texans’ electric bills had risen nearly 5%, or $1.8 billion per year, due to the increase in demand on the state power grid created by crypto mines.

Residents living near crypto mines have also complained that the amount of job creation promised by the facilities has not materialized and the noise of their operation is a nuisance.

“Texas should be reinvesting Texan’s tax money in things that truly bolster the economy long term, living wage, access to quality healthcare, world class public schools,” said state Sen. Molly Cook, D-Houston, who voted against the creation of the strategic fund. “Instead it feels like they’re almost gambling our money on something that is known to be really volatile and has not shown to be a tide that raises all boats.”

State Sen. Charles Schwertner, R-Georgetown, who authored the bill that created the fund, said at the time it passed that it will allow Texas to “lead and compete in the digital economy.”

Houston-based Fervo Energy closes $462M series E

fresh funding

Houston-based geothermal energy company Fervo Energy has closed an oversubscribed $462 million series E funding round, led by new investor B Capital.

“Fervo is setting the pace for the next era of clean, affordable, and reliable power in the U.S.,” Jeff Johnson, general partner at B Capital, said in a news release. “With surging demand from AI and electrification, the grid urgently needs scalable, always-on solutions, and we believe enhanced geothermal energy is uniquely positioned to deliver. We’re proud to support a team with the technical leadership, commercial traction, and leading execution capabilities to bring the world’s largest next-generation geothermal project online and make 24/7 carbon-free power a reality.”

The financing reflects “strong market confidence in Fervo’s opportunity to make geothermal energy a cornerstone of the 24/7 carbon-free power future,” according to the company. The round also included participation from Google, a longtime Fervo Partner, and other new and returning investors like Devon Energy, Mitsui & Co., Ltd., Mitsubishi Heavy Industries and Centaurus Capital. Centaurus Capital also recently committed $75 million in preferred equity to support the construction of Cape Station Phase I, Fervo noted in the release.

The latest funding will support the continued buildout of Fervo’s Utah-based Cape Station development, which is slated to start delivering 100 MW of clean power to the grid beginning in 2026. Cape Station is expected to be the world's largest next-generation geothermal development, according to Fervo. The development of several other projects will also be included in the new round of funding.

“This funding sharpens our path from breakthrough technology to large-scale deployment at Cape Station and beyond,” Tim Latimer, CEO and co-founder of Fervo, added in the news release. “We’re building the clean, firm power fleet the next decade requires, and we’re doing it now.”

Fervo recently won Scaleup of the Year at the 2025 Houston Innovation Awards, and previously raised $205.6 million in capital to help finance the Cape Station earlier this year. The company fully contracted the project's capacity with the addition of a major power purchase agreement from Shell this spring. Fervo’s valuation has been estimated at $1.4 billion and includes investments and support from Bill Gates.

“This new investment makes one thing clear: the time for geothermal is now,” Latimer added in a LinkedIn post. “The world desperately needs new power sources, and with geothermal, that power is clean and reliable. We are ready to meet the moment, and thrilled to have so many great partners on board.”
