A Houston company that's responding to rising energy demand by harnessing geothermal energy through its technology has again secured millions in funding. The deal brings Fervo's total funding secured this year to around $600 million.

Fervo Energy announced that it has raised $255 million in new funding and capital availability. The $135 million corporate equity round was led by Capricorn’s Technology Impact Fund II with participating investors including Breakthrough Energy Ventures, CalSTRS, Congruent Ventures, CPP Investments, DCVC, Devon Energy, Galvanize Climate Solutions, Liberty Mutual Investments, Mercuria, and Sabanci Climate Ventures.

The funding will go toward supporting Fervo's ongoing and future geothermal projects.

“The demand for 24/7 carbon-free energy is at an all-time high, and Fervo is one of the only companies building large projects that will come online before the end of the decade,” Fervo CEO and Co-Founder Tim Latimer says in a news release. “Investors recognize that Fervo’s ability to get to scale quickly is vital in an evolving market that is seeing unprecedented energy demand from AI and other sources.”

Additionally, Fervo secured a $120 million letter of credit and term loan facility from Mercuria, an independent energy and commodity group that previously invested in the company.

“In surveying power markets across the U.S. today, the need for next-generation geothermal is undeniable,” Brian Falik, group chief investment officer of Mercuria, adds. “We believe in Fervo not just because their EGS approach is cost-effective, commercially viable, and already being deployed at scale, but because they set ambitious targets and consistently deliver.”

In February, Fervo secured $244 million in a financing round led by Devon Energy, and in September, the company received a $100 million bridge loan for the first phase of its ongoing project in Utah. This project, known as Project Cape, represents a 100x growth opportunity for Fervo, as Latimer explained to InnovationMap earlier this year. As of now, Project Cape is fully permitted up to 2 GW and will begin generating electricity in 2026, per the company.

Other wins for Fervo this year include moving into its new headquarters in downtown Houston, securing a power purchase agreement with California, growing its partnership with Google, and being named amongst the year's top inventions by Time magazine.

Houston agriculture robotics co. raises $21.5M series A to grow climatetech solution

freshly funded

A Houston energy tech startup has raised a $21.5 million series a round of funding to support the advancement of its automated technology that converts field wastes into stable carbon.

Applied Carbon, previously known as Climate Robotics, announced that its fresh round of funding was led by TO VC, with participation from Congruent Ventures, Grantham Foundation, Microsoft Climate Innovation Fund, S2G Ventures, Overture.vc, Wireframe Ventures, Autodesk Foundation, Anglo American, Susquehanna Foundation, US Endowment for Forestry and Communities, TELUS Pollinator Fund for Good, and Elemental Excelerator.

The series A funding will support the deployment of its biochar machines across Texas, Oklahoma, Arkansas, and Louisiana.

"Multiple independent studies indicate that converting crop waste into biochar has the potential to remove gigatons of CO2 from the atmosphere each year, while creating trillions of dollars in value for the world's farmers," Jason Aramburu, co-founder and CEO of Applied Carbon, says in a news release. "However, there is no commercially available technology to convert these wastes at low cost.

"Applied Carbon's patented in-field biochar production system is the first solution that can convert crop waste into biochar at a scale and a cost that makes sense for broad acre farming," he continues.

Applied Carbon rebranded in June shortly after being named a top 20 finalist in XPRIZE's four-year, $100 million global Carbon Removal Competition. The company also was named a semi-finalist and awarded $50,000 from the Department of Energy's Carbon Dioxide Removal Purchase Pilot Prize program in May.

"Up to one-third of excess CO2 that has accumulated in the atmosphere since the start of human civilization has come from humans disturbing soil through agriculture," Joshua Phitoussi, co-founder and managing partner at TO VC, adds. "To reach our net-zero objectives, we need to put that carbon back where it belongs.

"Biochar is unique in its potential to do so at a permanence and price point that are conducive to mass-scale adoption of carbon dioxide removal solutions, while also leaving farmers and consumers better off thanks to better soil health and nutrition," he continues. "Thanks to its technology and business model, Applied Carbon is the only company that turns that potential into reality."

The company's robotic technology works in field, picking up agricultural crop residue following harvesting and converts it into biochar in a single pass. The benefits included increasing soil health, improving agronomic productivity, and reducing lime and fertilizer requirements, while also providing a carbon removal and storage solution.

"We've been looking at the biochar sector for over a decade and Applied Carbon's in-field proposition is incredibly compelling," adds Joshua Posamentier, co-founder and managing partner of Congruent Ventures. "The two most exciting things about this approach are that it profitably swings the agricultural sector from carbon positive to carbon negative and that it can get to world-scale impact, on a meaningful timeline, while saving farmers money."

What is it going to take to make Houston a leader in the energy transition? Access to capital, according to a panel from Venture Houston. Photo by Natalie Harms/EnergyCapital

Experts: Houston needs to unlock early-stage capital to lead the energy transition

show me the money

Last week, Tim Latimer sat on a panel that consisted mostly of his company's investors and discussed what he felt the missing piece still was for Houston's energy transition and innovation community.

“There’s no better place in the world than Houston to build and scale a climate tech startup," he says on a Venture Houston panel titled Seeding Sustainability: Unlocking the Power of Early Stage Investments.

“But I don’t know if I’m ready to make the claim that we’re the best place to start a business,” he adds.

Latimer, who co-founded Fervo Energy in the Bay Area in 2017 before relocating the company to Houston, explains that his company raised capital on the West Coast ahead of moving to Texas to grow and scale. This allowed the company, which recently announced the success of a major pilot, to tap into early stage funding and then make the most of every dollar raised by moving to a region where the money would last longer — and where there's talent, customers, and more.

“The dream for us to have a truly unlocked ecosystem is that the whole pattern can happen here in Houston, and the gap I see is that capital formation side,” he says.

Latimer was joined on the panel by some of Fervo's investors: Mark Cupta, managing partner of Prelude Ventures; Andrea Course, venture principal of Shell Ventures; and Joshua Posamentier, co-founder and managing partner of Congruent Ventures.

Each of the panelists weighed in on what it would take for Houston to emerge as a leader within the global energy transition. Cupta says that it's going to take the city time to build out activity, successful outcomes, talent, money, and more.

“The venture capital community is an ecosystem, and that ecosystem consists of multiple stakeholders that all have to work in concert with each other," he says. "It has to be a flywheel that spins up over time.”

Course, the only Houston-based investor on the panel, says that Houston has potential because it's got talent, industry, and money, or TIM, as she describes.

“I think Houston is actually the perfect place for becoming the energy transition capital. If you ask me, I think we already are.” Course explains. “It really just takes people doing what we’re doing now to make it even greater."

Posamentier, who previously shared his outlook on Houston in a Q&A with EnergyCapital, explains that access to funding isn't the only issue. “There’s a lot more money than there are investable opportunities at the moment,” he says.

The panel also weighed in on the difference between venture capital and funding coming out of corporations.

“VCs and CVCs have different timelines,” Course explains, saying VC firms have 5- to 7-year life cycles. After that, they need to see an exit to be able to provide that return. “With a CVC, we don’t really have that. Of course we want to show financial returns, but we are long-duration capital.

CVC is patient capital with value-add investors, but Course admits there's a longer due diligence because she wants to find a strategic stakeholder before an investment is made.

“The worst thing that could happen is that Shell gives you money, but they don’t give you business. We don’t want that,” she says.

Waiting for that right investor can be extremely important to company success, Latimer says from the founder perspective.

“It’s hard to put a hard dollar value on help, but our ability to have advisers and introductions from different types of investors … makes all the difference in the world,” he says on the panel. “A lot of startup founders think about their org design very critically and who they want to bring onto the team, and you should be deliberate on your cap table.”

Sustainability investor addresses startup challenges, Houston's capital shortages, and more

Q&A

It's been a challenging year for venture capital, but how are climatetech startups doing specifically? One Bay Area investor shares his point of view on this this topic ahead of Venture Houston next week.

Joshua Posamentier, co-founder and managing partner of Congruent Ventures, a San Francisco-based firm that invests in early-stage sustainable companies, is taking the stage at Venture Houston on September 7. Among others, Posamentier will be in conversation with the founder of one of his firm's portfolio companies, Fervo Energy, discussing seed and early-stage funding for sustainability-focused startups.

Venture Houston is presented by HX Venture Fund, a fund of funds that deploys capital into non-Houston firms to encourage investment in local startups. This year's theme is "Spotlighting the path for decarbonization in a digital world."

Posamentier, who has worked over a decade in this space, shares some of his thoughts on Houston as an energy transition leader, the challenges climate-tech startups face, and more in an interview with EnergyCapital.

EnergyCapital: How do you see Houston and its role in this energy transition, its challenges, its opportunities, etc.?

Josh Posamentier: I actually tend to disagree with the people that say Houston is too far down the oil and gas path. I mean, it's it's capitalism at the end of the day. There's money to be made in in climate mitigation technologies. People are going to go chase it, and I think Houston, of all places, is a pretty capitalistic city. And people are definitely not shy about chasing the next big opportunity. I mean, it was oil and natural gas before, and now it's now it's alternative energy. And so I think from that perspective, it's fine. There's a lot of money.

I think the biggest challenge is honestly, especially on a perception basis, a lot of the policy and social stuff that's endemic to Texas, which is a bummer. I mean, especially for younger talent. Austin had a shine, but I think that's largely gone and Houston never had it. So, I think it's something that needs to be overcome and needs to be thought about at a state level basis, especially if you're going to want to attract young entrepreneurial talent.

EC: What are some of the challenges energy transition startups are facing these days? How is your fund kind of supporting your portfolio companies through these challenges?

JP: There's some normalization that's had to happen over the last 9 to 12 months. As you know, corrections have come down the pipe in the venture ecosystem. By all accounts, it has been really frothy for the last few years, especially so in parts of climate. Some of that's due to the the proliferation of investment from non climate-specific firms. And it's, in many ways, decoupled from the ups and downs of different parts of the venture ecosystem, but it also has different timelines. I think not everyone always appreciates what that means and what that implies for for startups. So there's a lot of frustration and a lot of missed expectations in the early stage part of the ecosystem that are slowly getting fixed. I think getting expectations more in line with reality is going to help immensely.

The other thing is just figuring out how to talk more in a language that venture investors understand. I think that's a little bit of a challenge. There's there's actually a pretty big gap between if you're an oil and gas developer and thinking about how you fund that kind of a business versus how you fund a technology-enabling business. Fervo Energy is an interesting example. It's a tech company, but now it's really a tech enabled developer because they have no choice but to do that full stack. They went to school out here. They understand the ecosystem. They've really taken the effort to really understand all the capital players. And so we're waiting to see how that ultimately plays out.

But there's just different capital. I think it is a little challenging. And this is a good thing. There does need to be a way, I think, to just get people more exposure to to the market there — in the Houston market specifically. If you're spinning at Stanford, there are hundreds of VCs within walking distance. In Houston, the ones I know I can count on one hand.

EC: Has that pace of commercialization changed over the years or have founders found ways to survive that valley of death?

JP: I don't think anything's really changed fundamentally. I think people have gotten a little more clever about understanding how the adoption occurs, and figuring out how to phase into those processes that that comes with experience. But there's only so much acceleration you can do when you're dealing with critical infrastructure. You know, people are not going to want to just jump right in, rip out, and replace things that keep the lights on. And so you just have to figure out how to how to capitalize a business in such a way that you can you can live with those kinds of timelines. Venture capital is a fantastic tool, and it is far from the right tool for every problem. And so there are plenty of opportunities to deploy other tools that are more appropriate to different kinds of different kinds of challenges.

EC: What attracted you to investing in Fervo Energy?

JP: So, it's how we think about portfolio construction. Fervo has an amazing team, which we will bend a lot of rules for, and we saw this opportunity as something they could build a ton of value by validating the tech, establishing a huge land position, and then raising different kinds of capital for the out years and for the project development. A bunch of our companies took venture capital to develop a technology, and then they know that venture is not the right class of capital to then scale that throughout the world and whatever. So they would basically raise other forms of capital in the out years to deploy the technologies.

EC: And one of those options is government funding. How do your portfolio companies utilize that?

JP: A big chunk of our portfolio has some government money, even if it's very early stage research grants or something like that. I see government money being the most effective in a couple of ways. One way obviously is to get the core research out of it versus just spin it into something more commercial that we can all then look at.

The other place that is really exciting is in is getting technologies to scale where they're then cost effective without further subsidies. When we underwrite companies, we are very explicitly underwriting them in the absence of subsidies at scale. The assumption is those are just there to basically bridge the gap between "this is totally uneconomic because it's a tiny, tiny little factory or something" versus "it would be plenty economic if it were a big factory." So, if they can just bridge that gap with a little bit of government money.

We've been through this this cycle a couple of times, and we can't in good faith underwrite anything assuming that government subsidies are going to continue. We very much believe it's a bridge — it's got to be a bridge to something. It can't be a bridge to nowhere. And I think there are a lot of companies out there today that are almost designed to just pump the government incentives, and that's not a recipe for a business that can grow on its own over time.

Annual Houston conference to target topics on digitalization of decarbonization

thought leadership

An event that brings top venture capitalists to Houston returns for its third year — and this time the topic of conversation is the energy transition.

Venture Houston, taking place on September 7, is presented by HX Venture Fund, a fund of funds that deploys capital into non-Houston firms to encourage investment in local startups. This year's theme is "Spotlighting the path for decarbonization in a digital world," and Sandy Guitar, managing partner at HXVF, tells EnergyCapital that while that might sound like a narrow topic, attendees will see at the event how broad a theme it really is.

"We're calling it digitalization to decarbonization in order to help identify the fact that decarbonization is just a market that you sell into — the technologies are very broadly defined," Guitar says. "Underneath that, the decarbonization market happens to involve everything that is better, cheaper, and faster."

The event, which has its ticket registration open now, has a full agenda with several keynote addresses and panels featuring venture leaders, CEOs, startup founders, and more from Houston and beyond. There will also be networking breaks and other activations, including a breakfast presented by DivInc and Capital Connect on September 6. This event features curated collisions for a select VCs and founders.

The conference's first panel, "Seeding Sustainability: Unlocking the Power of Early Stage Investments," includes Josh Posamentier, co-founder and managing partner of Congruent Ventures, who will share the stage with the founder of one of his firm's portfolio companies, Tim Latimer of Fervo Energy, among others.

To Posamentier, one of the things he hopes attendees takes away is how timely decarbonization is — especially in Houston.

"If I had one ask, it would be that people, especially for this audience, double down and mobilize more toward alternative energy," he tells EnergyCapital. "Take all the learnings, all the skills that come from conventional energy and repurpose them. I think there's it's a bigger market — more is being spent on renewables now than on oil and gas development and, you've got got a good 50 years of insane growth ahead."

And, as Guitar adds, the energy transition is not something that only affects the companies building the technology or working within the energy industry.

"I do think it's important to see the decarbonization not as a hard tech event, but as everything that touches carbon, which is basically everything in our planet in just the coal previously," she says. "Everything we make and use touches the climate."

Houston clean energy pioneer earns prestigious Welch Foundation award

Awards Season

A Rice University professor has earned a prestigious award from the Houston-based Welch Foundation, which supports chemistry research.

The foundation gave its 2025 Norman Hackerman Award in Chemical Research to Haotian Wang for his “exceptionally creative” research involving carbon dioxide electrochemistry. His research enables CO2 to be converted into valuable chemicals and fuels.

The award included $100,000 and a bronze sculpture.

“Dr. Wang’s extensive body of work and rigorous pursuit of efficient electrochemical solutions to practical problems set him apart as a top innovator among early-career researchers,” Catherine Murphy, chairwoman of the foundation’s Scientific Advisory Board, said in a news release.

Wang is an associate professor in the Department of Chemical and Biomolecular Engineering at Rice. The department’s Wang Group develops nanomaterials and electrolyzers for energy and environmental uses, such as energy storage, chemical and fuel generation, green synthesis and water treatment.

Wang also is co-founder of Solidec, a Houston startup that aims to turn his innovations into low-carbon fuels, carbon-negative hydrogen and carbon-neutral peroxide. The startup extracts molecules from water and air, then transforms them into pure chemicals and fuels that are free of carbon emissions.

Solidec has been selected for Chevron Technology Ventures’ catalyst program, a Rice One Small Step grant, a U.S. Department of Energy grant, and the first cohort of the Activate Houston program.

“Dr. Wang’s use of electrochemistry to close the carbon cycle and develop renewable sources of industrial chemicals directly intersects with the Welch Foundation mission of advancing chemistry while improving life,” Fred Brazelton, chairman and director of the Welch Foundation, said in the release.

Ramamoorthy Ramesh, executive vice president for research at Rice University, added: “We are proud to (Dr. Wang) at Rice. He’s using chemical engineering to solve a big problem for humanity, everything that the Welch Foundation stands for.”

Last year, the Hackerman Award went to Baylor College of Medicine's Livia Schiavinato Eberlin, who's known for her groundbreaking work in the application of mass spectrometry technologies, which are changing how physicians treat cancer and analyze tissues. Read more here.

Houston venture firm invests in Virginia fusion power plant company in collaboration with TAMU

fusion funding

Houston-based climate tech venture firm Ecosphere Ventures has partnered with Virginia Venture Partners and Virginia Innovation Partnership Corporation’s venture capital program to invest in Virginia-based NearStar Fusion Inc., which develops fusion energy power plants.

NearStar aims to use its proprietary plasma railgun technology to safely and affordably power baseload electricity on and off the power grid through a Magnetized Target Impact Fusion (MTIF) approach, according to a news release from the company.

NearStar’s power plants are designed to retrofit traditional fossil fuel power plants and are expected to serve heavy industry, data centers and military installations.

“Our design is well-suited to retrofit coal-burning power plants and reuse existing infrastructure such as balance of plant and grid connectivity, but I’m also excited about leveraging the existing workforce because you won’t need PhDs in plasma physics to work in our power plant,” Amit Singh, CEO of NearStar Fusion, said in a news release.

NearStar will also conduct experiments at the Texas A&M Hypervelocity Impact Laboratory (HVIL) in Bryan, Texas, on prototype fuel targets and evolving fuel capsule design. The company plans to publish the results of the experiments along with a concept paper this year. NearStar will work with The University of Alabama in Huntsville (UAH) to develop computer performance models for target implosions.

NearStar’s MTIF approach will utilize deuterium, which is a common isotope of hydrogen found in water. The process does not use tritium, which NearStar believes will save customers money.

“While avoiding tritium in our power plant design reduces scientific gain of the fusion process, we believe the vastly reduced system complexity and cost savings of eliminating complicated supply chains, regulatory oversight, and breeding of tritium allows NearStar to operate power plants more profitably and serve more customers worldwide, ”Douglas Witherspoon, NearStar founder and chief scientist, said in a news release.

Houston’s Ecosphere Ventures invests in climate tech and sustainability innovations from pre-seed to late-seed stages in the U.S. Ecosphere also supports first-time entrepreneurs and technical founders.

Solar farms are booming and putting thousands of hungry sheep to work

Solar Power

On rural Texas farmland, beneath hundreds of rows of solar panels, a troop of stocky sheep rummage through pasture, casually bumping into one another as they remain committed to a single task: chewing grass.

The booming solar industry has found an unlikely mascot in sheep as large-scale solar farms crop up across the U.S. and in the plain fields of Texas. In Milam County, outside Austin, SB Energy operates the fifth-largest solar project in the country, capable of generating 900 megawatts of power across 4,000 acres.

How do they manage all that grass? With the help of about 3,000 sheep, which are better suited than lawnmowers to fit between small crevices and chew away rain or shine.

The proliferation of sheep on solar farms is part of a broader trend — solar grazing — that has exploded alongside the solar industry.

Agrivoltaics, a method using land for both solar energy production and agriculture, is on the rise with more than 60 solar grazing projects in the U.S., according to the National Renewable Energy Laboratory. The American Solar Grazing Association says 27 states engage in the practice.

"The industry tends to rely on gas-powered mowers, which kind of contradicts the purpose of renewables," SB Energy asset manager James Hawkins said.

A sunny opportunity
Putting the animals to work on solar fields also provides some help to the sheep and wool market, which has struggled in recent years. The inventory of sheep and lamb in Texas fell to 655,000 in January 2024, a 4% drop from the previous year, according to the most recent figures from the U.S. Department of Agriculture.

Because solar fields use sunny, flat land that is often ideal for livestock grazing, the power plants have been used in coordination with farmers rather than against them.

Sheepherder JR Howard accidentally found himself in the middle of Texas' burgeoning clean energy transition. In 2021, he and his family began contracting with solar farms — sites with hundreds of thousands of solar modules — to use his sheep to eat the grass.

What was once a small business has turned into a full-scale operation with more than 8,000 sheep and 26 employees.

"Just the growth has been kind of crazy for us," said Howard, who named his company Texas Solar Sheep. "It's been great for me and my family."

Following the herd
Some agriculture experts say Howard's success reflects how solar farms have become a boon for some ranchers.

Reid Redden, a sheep farmer and solar vegetation manager in San Angelo, Texas, said a successful sheep business requires agricultural land that has become increasingly scarce.

"Solar grazing is probably the biggest opportunity that the sheep industry had in the United States in several generations," Redden said.

The response to solar grazing has been overwhelmingly positive in rural communities near South Texas solar farms where Redden raises sheep for sites to use, he said.

"I think it softens the blow of the big shock and awe of a big solar farm coming in," Redden said.

Fielding more research
Agrivoltaics itself isn't new. Solar farms are land-intensive and require a lot of space that could be used for food production. Agrivoltaics compensates by allowing the two to coexist, whether growing food or caring for livestock.

There is a lot still unknown about the full effects of solar grazing, said Nuria Gomez-Casanovas, an assistant professor in regenerative system ecology at Texas A&M University.

Not enough studies have been done to know the long-term environmental impacts, such as how viable the soil will be for future agriculture, although Gomez-Casanovas suspects solar grazing may improve sheep productivity because the panels provide shade and can be more cost-efficient than mowing.

"We really have more questions than answers," Gomez-Casanovas said. "There are studies that show that the land productivity is not higher versus solar alone or agriculture alone, so it's context-dependent."

As one of Texas' largest solar sheep operators, Howard has more clients than he can handle. He expects to add about 20 more employees by the end of this year, which would nearly double his current workforce. As for the sheep, he has enough already.
