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.

Utah solar company acquires Houston projects, expands to Texas

solar deals

Utah-based solar technology and battery storage company SunPower has announced its expansion into Texas by acquiring “prime project assets” from Houston installer Green Light Solar.

As part of the deal, Green Light Solar CEO James Garrett will lead SunPower’s U.S. installation group. Garrett is based in the Houston area, according to LinkedIn.

Green Light Solar focuses on residential and commercial solar installations, battery backups and whole-home generators throughout Texas, Louisiana, Oklahoma and Colorado. As of press time, SunPower had not disclosed which specific projects or assets were included in the acquisition.

In addition to the Green Light acquisition, SunPower also announced its second strategic partnership with Fort Worth-based SOLRITE Energy, which provides solar and battery project financing and virtual power plant capabilities.

Through the partnership, SunPower plans to expand its residential solar and battery storage business and grow its virtual power plant (VPP) network in Texas.

A virtual power plant is a network of connected energy sources that can supply electricity to the grid when demand is high. The network draws on energy stored in individual residential and commercial battery systems. VPPs can also help participating homeowners generate additional revenue by selling their stored power.

“SOLRITE not only sources projects to us but also provides project funding for innovative systems with large batteries connected to a VPP, enabling power sales into the open market,” T. J. Rodgers, SunPower CEO, said in a news release. “That VPP capability provides an extra source of income that SOLRITE shares with homeowners and EPCs, making SOLRITE an attractive partner.”

SunPower will bring its sales, installation and lifetime warranty support to the partnership, while SOLRITE will provide its virtual power plant platform and solar financing capabilities, according to the release.

"Building our VPP business is a key part of SunPower’s growth strategy going forward,” Kapil Rai, EVP of Direct at SunPower, added in the release. “Our partnership with SOLRITE gives us a path to bring together customer acquisition, solar, storage deployment, and financing to develop this business in Texas and beyond.”

Solid-state generator company secures $9M in financing, names CTO

fresh financing

ATS Energy has secured a $9 million investment to help commercialize its solid-state generator technology, a representative from the company tells Energy Capital.

The Colorado-based company is a member of Houston's Greentown Labs climatech community and was named the second most-promising startup in the Innovations for Traditional Energy, Electricity, & the Grid track during CERA Week's Energy Venture Day and Pitch Competition in March.

ATS's technology converts industrial waste heat into electricity via its proprietary thermoelectric cartridges, according to a news release. The cartridges convert the otherwise wasted thermal energy directly into usable electricity with no turbine, no moving parts and no emissions.

"We have spent years building a proven track record of breakthrough technology," Doug Hudson, CEO of ATS Energy, said in the release. "What has developed over the past year is that markets are moving toward ATS Energy, said in the release. We've moved well beyond early interest to commercial commitments, active proposals and a pipeline that continues to expand across multiple industrial sectors. That puts us in a tremendous position to meet the moment in delivering energy to industry. This investment responds to real commercial opportunity, and it positions ATS Energy to scale production, meet customer demand faster, and drive commercial deployments."

According to the release, ATS plans to complete and deploy its first commercial generator using the thermoelectric cartridges by mid-2027. The company shared that it plans to begin revenue-generating operations next year, as well.

ATS has also named Edward Ganja as its new CTO. Ganja previously served as a technology advisor for ATS and spent more than 30 years at Shell, most recently as vice president of catalyst and analytical technology in Houston, according to LinkedIn.

"Having worked closely with the team as a Technology Adviser, I am thrilled to step into the Chief Technology Officer role to lead our technology strategy and advanced materials scale-up," Ganja shared in a LinkedIn post. "ATS is tackling crucial energy challenges, and I look forward to working with our talented team, partners, and industry colleagues to accelerate our commercial development and technological footprint."

A representative from the company shares that ATS has three employees in Texas, including two in Houston. The company is targeting industrial facilities, including Gulf Coast refineries and petrochemical plants, for its production model, which will leverage established manufacturing capabilities to help quickly scale its commercial pipeline.

"We are scaling manufacturing with the discipline required for commercial-grade industrial deployment, moving beyond proof-of-concept to deliver mission-critical equipment," Terry Hill, COO of ATS, added in the release. "We've been building the supply chain, identifying the right manufacturing partners and putting the processes in place to move toward repeatable production. By leveraging contract manufacturing, we can focus our capital on the technology, the product and our customers rather than building factories. Just as importantly, we're working to reduce the time between installations so we can respond to the demand we're seeing in the market."

ATS won the prestigious Earthshot Prize in the Fix Our Climate category in 2024. The Earthshot Prize, founded by Prince William, awards £1 million to five energy startups each year over a decade.
