Houston-based Ara Partners, a private equity firm that focuses on industrial decarbonization investments, is receiving up to $725 million from a Tennessee-based family office to launch an energy decarbonization unit.

HF Capital, the Knoxville, Tennessee-based investment arm of the Haslam family, made the multimillion-dollar commitment to set up Ara Energy Decarbonization. The new business will work toward reducing carbon emissions at ethanol plants, natural gas power plants, and other traditional energy assets.

The Haslam family founded Pilot Co., North America’s largest transportation fuel business and chain of travel centers. Shameek Konar, former CEO of Pilot, has been tapped to lead Ara Energy Decarbonization.

“It is an uncomfortable truth that highly pollutive energy sources are going to play an essential role in delivering an energy transition over the next several decades,” Charles Cherington, co-founder and managing partner of Ara, says in a news release. “We can ignore these staggering carbon emissions, or we can apply our proven methods and financing expertise to decarbonize the conventional energy value chain.”

The energy sector accounts for more than 75 percent of global greenhouse gas emissions.

“The world’s energy demands are increasing and complex, and renewable power needs time and support for it to fulfill rising global energy demand. Ara’s … skillset, portfolio network, and decarbonization management knowledge [are] perfectly positioned to attack the carbon-intensive energy sector,” Konar says.

Ara Partners closed its third private equity fund in December 2023 with over $2.8 billion in new commitments. As of June 30, 2024, Ara Partners had about $6.3 billion of assets under management.

2 Houston energy leaders bet on carbon capture with recent acquisitions

the view from heti

CCUS will play a pivotal role in the global energy transition by decarbonizing carbon-intensive industries, including energy, chemicals, cement, and steel. CCUS is one of the few proven technologies to significantly lower net emissions. However, the unique nature of decarbonization presents many complex challenges. With greater funding and growing policy support, the widespread adoption of CCUS technologies is becoming more technically feasible and economically viable than ever before.

Houston, with its existing CCUS infrastructure, large concentration of CCUS expertise, and high storage capacity, is the ideal location to deploy and derisk CCUS projects at unprecedented speed and scale. Recently, two HETI members announced acquisition and investment into carbon capture businesses.

SLB + Aker Carbon Capture (ACC)

SLB, a pioneer in carbon capture technologies, announced an agreement to acquire major ownership in Aker Carbon Capture (ACC), a pure-play carbon capture company. The move combines SLB’s established CCUS business with ACC’s innovative CCUS technology to support accelerated industrial decarbonization at scale.

“For CCUS to have the expected impact on supporting global net-zero ambitions, it will need to scale up 100-200 times in less than three decades,” said Olivier Le Peuch, chief executive officer, SLB. “Crucial to this scale-up is the ability to lower capture costs, which often represent as much as 50-70% of the total spend of a CCUS project. We are excited to create this business with ACC to accelerate the deployment of carbon capture technologies that will shift the economics of carbon capture across high-emitting industrial sectors.”

Chevron New Energies + ION Clean Energy

Chevron New Energies, a division of Chevron U.S.A. Inc., announced a lead investment in ION Clean Energy (ION), which provides post-combustion point-source capture technology through its third-generation ICE-31 liquid amine system. This investment expands and complements Chevron’s growing portfolio of CCUS technologies.

“ION’s solvent technology, combined with Chevron’s assets and capabilities, has the potential to reach numerous emitters and support our ambitions of a lower carbon future,” said Chris Powers, vice president of CCUS & Emerging, Chevron New Energies. “We believe collaborations like this are essential to our efforts to grow carbon capture on a global scale.”

“This investment from Chevron is a huge testament to the hard work of our team and the potential of our technology,” said ION founder and executive chairman Buz Brown. “We appreciate their collaboration and with their investment we expect to accelerate commercial deployment of our technology so that we can realize the kind of wide-ranging commercial and environmental impact we’ve long envisioned.”

Chevron supports 2 carbon emissions tech startups

making moves

Chevron Technology Ventures has added two startups to its portfolio — one to its startup accelerator and one via an investment.

Delaware-based Compact Membrane Systems closed an oversubscribed series A funding round of $16.5 million led by Pangaea Ventures. CTV also contributed to the round, along with GC Ventures, Solvay Ventures, and Technip Energies.

CMS's technology is targeting carbon capture in traditionally hard-to-abate sectors, such as steel, cement, etc., which represent more than a tenth of worldwide emissions. The CMS platform, which operates in a 10,000-square-foot lab and manufacturing facility in Delaware, is a fully electrified and low-cost solution.

“We are delighted to have secured such a strong group of investors who share our vision for delivering a revolutionary carbon capture technology for industrial applications,” says Erica Nemser, CEO of Compact Membrane Systems, in a news release. “This oversubscribed funding round catalyzes our ability to deliver large projects. Deployment of our commercial systems by 2026 will have measurable environmental and economic benefits to our customers and society.”

It's the latest investment from CTV's $300 million Future Energy Fund II, which specifically "focuses on industrial decarbonization, emerging mobility, energy decentralization, and the growing circular economy," says Jim Gable, vice president of innovation at Chevron and president of CTV.

“The technology that CMS has developed has the potential to drive further efficiencies and cost reduction along the CCUS value chain, supporting decarbonization of hard-to-abate sectors and complementing our existing portfolio of investments in this space,” Gable says in the release.

The company is planning to use its new funding to further develop and commercialize its product by 2026.

Another startup has announced support from Chevron last month. Calgary, Alberta-based Arolytics Inc. announced last month that its been accepted into CTV's Catalyst Program. The company has an emissions software and data analytics platform for the oil and gas sector, and the program will help it further develop and deploy its technology.

"Being selected for the Catalyst Program is an amazing opportunity for Arolytics," says Liz O'Connell, CEO of Arolytics, in a news release. "The interest from Chevron demonstrates the oil and gas industry's desire to reduce emissions. It aligns closely with Arolytics' mission to build and execute efficient emissions management programs that enable industry to become leaders in emissions management."

Arolytics' technology, which includes AroViz, an emissions management software, and AroFEMP, an emissions forecasting model, targets methane emissions specifically, per the release.

Launched in 2017, the CTV Catalyst Program accelerates early-stage companies that are working on innovations within the energy industry. Arolytics will use the program to make key connections, identify important use cases, and expand into the U.S. Market.

Q&A: Chevron's unique clean energy studio role in Houston entrepreneur community

matchmaking innovation

A new program from Houston-based Chevron Technology Ventures is rethinking how best to commercialize research-based technology.

This spring, Chevron Studio announced its second cohort of its program that matches entrepreneurs with promising technologies coming out of universities and labs. The overall goal of the studio — a collaboration between Chevron and the National Renewable Energy Laboratory, or NREL — is to scale up and commercialize early-stage technologies that have the potential to impact the future of energy.

Once selected, there are three phases of the program. After the entrepreneur applications closed in March, the first step was matching the selected entrepreneurs with the inventors of the selected intellectual properties, which will occurs over three to four months. The next phase includes scaling up the product — something that will take one to two years, depending on the tech. The last step would be a trial or a pilot program that includes rolling out a minimum viable product at commercial scale at Chevron or an affiliate. The next cohort application period will open next month.

Gautam Phanse is the strategic relationship manager for Chevron Technology Ventures. He joins InnovationMap for a Q&A to explain more about the opportunity.

What types of technologies is Chevron looking to bring into commercialization through this program? How is the program different from existing accelerators/incubators/etc.?

Gautam Phanse: Chevron Technology Ventures brings external innovation to Chevron. Key focus areas for CTV are industrial decarbonization, emerging mobility, energy decentralization, and the growing circular carbon economy. Chevron Studio is one of the tools to achieve this goal. The current focus areas for Chevron Studio are: carbon utilization, hydrogen and renewable energy, energy storage systems, and solutions for circular economy. These focus areas will be reviewed every year and additional areas could be brought into the mix.

The goal of Chevron Studio is to scale up and commercialize technology developed in the Universities and National Labs. We curate the intellectual property developed at universities and national labs and provide a platform to match entrepreneurs with the IP. The program provides seed funding and a pathway through incubation, pilot and field trials to scale up the technologies. The uniqueness of this program is its target and the breadth of its scope — all the way from incubation to field trials.

How does Chevron Technology Ventures and the National Renewable Energy Laboratory collaborate on this project? What role does each entity play?

GP: CTV has a long history of supporting innovation and the startup community. And over the years we’ve seen the consistent gaps and the struggles that the startup companies have in scaling up technologies. We also have a long history of working with national labs and universities and have seen the challenges in getting these technologies out of the labs. The idea for Chevron Studio grew out of these challenges.

NREL’s Innovation and Entrepreneurship Center manages Chevron Studio, working closing with entrepreneurs and guiding them through the program while leveraging capabilities at the lab and activating the IEC’s network of cleantech startups, investors, foundations, and industry partners.

What are you looking for from the entrepreneur applicants? Who should apply?

GP: We are looking for entrepreneurs who are seeking their next opportunity. They should have a passion in lower carbon solutions and the patience to work on early-stage technologies to see them through scale up and commercialization. Aspiring entrepreneurs with demonstrated passion are also welcome to apply. The entrepreneurs are expected to build a team, raise funds and grow the business providing competitive solutions to the industry.

Tell me about cohort 1. How did it go and what were the participants able to accomplish?

GP: We were really excited about the response we got from both the entrepreneur community and the universities and national labs. We had a strong pool of entrepreneurs and a great mix of IP and frankly had a tough time making the selection. The first cohort had four entrepreneurs in the initial discovery phase. Some of them have now graduated, and we will be announcing the participants in the next phase — for scaling up — shortly.

3 Houston energy companies rank among most innovative startups in Texas

report card

Three Houston companies claimed spots on LexisNexis's 10 Most Innovative Startups in Texas report, with two working in the geothermal energy space.

Sage Geosystems claimed the No. 3 spot on the list, and Fervo Energy followed closely behind at No. 5. Fintech unicorn HighRadius rounded out the list of Houston companies at No. 8.

LexisNexis Intellectual Property Solutions compiled the report. It was based on each company's Patent Asset Index, a proprietary metric from LexisNexis that identifies the strength and value of each company’s patent assets based on factors such as patent quality, geographic scope and size of the portfolio.

Houston tied with Austin, each with three companies represented on the list. Caris Life Sciences, a biotechnology company based in Dallas, claimed the top spot with a Patent Asset Index more than 5 times that of its next competitor, Apptronik, an Austin-based AI-powered humanoid robotics company.

“Texas has always been fertile ground for bold entrepreneurs, and these innovative startups carry that tradition forward with strong businesses based on outstanding patent assets,” Marco Richter, senior director of IP analytics and strategy for LexisNexis Intellectual Property Solutions, said in a release. “These companies have proven their innovation by creating the most valuable patent portfolios in a state that’s known for game-changing inventions and cutting-edge technologies.We are pleased to recognize Texas’ most innovative startups for turning their ideas into patented innovations and look forward to watching them scale, disrupt, and thrive on the foundation they’ve laid today.”

This year's list reflects a range in location and industry. Here's the full list of LexisNexis' 10 Most Innovative Startups in Texas, ranked by patent portfolios.

  1. Caris (Dallas)
  2. Apptronik (Austin)
  3. Sage Geosystems (Houston)
  4. HiddenLayer (Austin)
  5. Fervo Energy (Houston)
  6. Plus One Robotics (San Antonio)
  7. Diligent Robotics (Austin)
  8. HighRadius (Houston)
  9. LTK (Dallas)
  10. Eagle Eye Networks (Austin)

Sage Geosystems has partnered on major geothermal projects with the United States Department of Defense's Defense Innovation Unit, the U.S. Air Force and Meta Platforms. Sage's 3-megawatt commercial EarthStore geothermal energy storage facility in Christine, Texas, was expected to be completed by the end of last year.

Fervo Energy fully contracted its flagship 500 MW geothermal development, Cape Station, this spring. Cape Station is currently one of the world’s largest enhanced geothermal systems (EGS) developments, and the station will begin to deliver electricity to the grid in 2026. The company was recently named North American Company of the Year by research and consulting firm Cleantech Group and came in at No. 6 on Time magazine and Statista’s list of America’s Top GreenTech Companies of 2025. It's now considered a unicorn, meaning its valuation as a private company has surpassed $1 billion.

Meanwhile, HighRadius announced earlier this year that it plans to release a fully autonomous finance platform for the "office of the CFO" by 2027. The company reached unicorn status in 2020.

Tech entrepreneur turned climate investor is on a mission to monetize carbon removal

now streaming

The climate conversation is evolving — fast. It’s no longer just about emissions targets and net-zero commitments. It’s about capital, infrastructure, and execution at industrial scale.

That’s exactly where Yao Huang operates. A seasoned tech entrepreneur turned climate investor, Yao brings sharp clarity to one of the biggest challenges in climate innovation: how do we fund and scale technologies that remove carbon without relying on goodwill or government subsidies?

In this episode of the Energy Tech Startups Podcast, Yao sits down with hosts Jason Ethier and Nada Ahmed for a wide-ranging conversation that redefines how we think about decarbonization. From algae-based photobioreactors that capture CO₂ at the smokestack, to financing models that mirror real estate and infrastructure—not venture capital—Yao lays out a case for why the climate fight will be won or lost on spreadsheets, not slogans.

Her message is as bold as it is practical: this isn’t about saving the planet for the sake of it. It’s about building profitable, resilient systems that scale. And Houston, with its industrial base and project finance expertise, is exactly the place to do it.

The 40-Gigaton Challenge—and a Pandemic Pivot

Yao’s entry into climate wasn’t part of a long-term plan. It was sparked by a quiet moment during the pandemic—and a book.

Reading How to Avoid a Climate Disaster by Bill Gates, she came to two uncomfortable realizations:

  1. The people in power don’t actually have this figured out, and
  2. She would be alive to suffer the consequences.

That insight jolted her out of the traditional tech world and into climate action. She studied at Stanford, surrounded herself with mentors, and began diving into early-stage climate deals. But she quickly realized that most of the solutions she was seeing were still years away from commercialization.

So she narrowed her focus: no R&D moonshots, no science experiments—just deployable solutions that could scale now.

Carbon Optimum: Where Algae Meets Infrastructure

That’s how she found Carbon Optimum, a company using algae photobioreactors to remove CO₂ directly from industrial emissions. Their approach is both elegant and economic:

  • Install algae reactors next to major emitters like coal and cement plants.
  • Feed the algae with flue gas, allowing it to absorb CO₂ in a controlled system.
  • Harvest the algae and convert it into valuable commodities like bio-oils, fertilizer, and food ingredients.

It’s a nature-based solution, enhanced by engineering.
One acre of tanks can capture emissions and generate profit—without subsidies.

“This is one of the few solutions I’ve seen that can scale profitably and quickly,” Yao says. “And we’re not inventing anything new—we’re just doing it better.”

The Real Problem? It’s Capital, Not Carbon

As an investor, Yao is blunt: most climate startups are misaligned with the capital markets.

They’re following a tech startup playbook—built for SaaS, not steel. But building climate infrastructure requires a completely different approach: project finance, blended capital, debt structures, carbon credit integration, and regulatory incentives.

“Climate tech is more like real estate or healthcare than software,” Yao explains. “You don’t raise six rounds of venture. You build a stack—grants, equity, debt, tax credits—and you structure your project like infrastructure.”

It’s not just theory. It’s exactly how Carbon Optimum is expanding—through partnerships, offtake agreements, and real-world deployments. And it’s why she believes many climate startups fail: they don’t speak the language of finance.

Houston’s Role in the Climate Capital Stack

For Yao, Houston isn’t just a backdrop—it’s a strategic asset.

The city’s deep bench of project finance professionals, commodity traders, lawyers, and infrastructure veterans makes it uniquely positioned to lead the deployment phase of climate solutions.

“We’ve been calling it the wrong thing,” she says. “This isn’t just about climate—it’s an energy transition. And Houston knows how to build energy infrastructure at scale.”

Still, she notes, the ecosystem needs to evolve. Less education, more execution. Fewer workshops, more closers.

“Houston could be the epicenter of this movement—if we activate the right people and get the right projects over the line.”

From Carbon Capture to Circular Economies

The potential applications of Carbon Optimum’s algae platform go beyond carbon capture. Because the output—algae biomass—can be converted into:

  • Renewable oil
  • High-efficiency fertilizers (critical in today’s geopolitically fragile supply chains)
  • Food ingredients rich in protein and nutrients
  • Even biochar, a highly stable form of carbon sequestration

It’s scalable, modular, and location-agnostic. In island nations, Yao notes, these systems can offer energy independence by turning waste CO₂ into local energy and fertilizer—without needing to import fuels or food.

“It’s not just emissions reduction. It’s economic sovereignty through circular systems.”

Doing, Not Just Talking

One of Yao’s key takeaways for founders? Don’t waste time. Climate startups don’t have the luxury of trial-and-error cycles stretched over years.

“Founders need to get real about what it takes to scale: talent, capital, storytelling, partnerships. If you’re not ready to do that, maybe you should be a CSO, not a CEO.”

She also points out that founders don’t need to hire everyone—they need to tap the right networks. And in cities like Houston, those networks exist—if you know how to motivate them.

“It takes a different kind of leadership. You’re not just raising money—you’re moving people.”

Why This Episode Matters

This conversation is for anyone who’s serious about scaling real solutions to the climate crisis. Whether you’re a founder navigating capital markets, an investor seeking return and impact, or a policymaker designing the frameworks — Yao Huang offers a grounded, urgent, and actionable perspective.

It’s not about hope. It’s about execution.

Rice scientist receives $2 million award for research on 'new type of fuel'

winner, winner

Rice University chemistry professor László Kürti was named as a recipient of the 2025 Ross M. Brown Investigator Award from the California Institute of Technology’s Brown Institute for Basic Sciences.

Kürti is one of eight mid-career faculty members to receive up to $2 million over five years for their research in the physical sciences.

“I’m greatly honored,” Kürti said in a news release. “We will learn a tremendous amount in the next five years and gain a much clearer understanding of the challenges ahead.”

Kürti was selected for the research he’s been developing for six years on a molecule called tetrahedral N4, which studies show can release large amounts of energy on demand. The molecule can also decompose directly into nitrogen gas without producing carbon dioxide or water vapor. Kürti believes N4 can be used as a "new type of fuel for vehicles."

“Eventually, N4 and other stable, neutral polynitrogen cages could be used to power rockets, helping us reach the moon or Mars faster and with heavier payloads,” he added in this release.

The Brown Investigator Awards were founded by entrepreneur and Caltech alumnus Ross M. Brown and established by the Brown Science Foundation in 2020. The organization has recognized 21 scientists over the last five years.

“Midcareer faculty are at a time in their careers when they are poised and prepared to make profound contributions to their fields,” Brown said in the news release. “My continuing hope is that the resources provided by the Brown Investigator Awards will allow them to pursue riskier innovative ideas that extend beyond their existing research efforts and align with new or developing passions, especially during this time of funding uncertainty.”
