With $200M raised last year, Houston cleans up on new report tracking climatetech funding

We're No. 5

Climatech funding for Houston-area startups crept toward the $200 million mark in 2023 — putting it ahead of Dallas-Fort Worth, Austin, and several other major metro areas and making it a standout among U.S. climatech hubs.

Last year, the Houston area collected $199.94 million in climatech funding across 14 deals, according to PitchBook data analyzed by Revolution Growth, a venture capital firm based in Washington, D.C.

“With its deep-rooted energy sector, Houston is an attractive HQ for companies innovating within renewable energy, carbon capture, and emissions reduction,” Revolution says. “Partnerships with oil and gas companies also provide unique collaboration opportunities for climate tech startups, accelerating market adoption and helping companies achieve scale quickly.”

Los Angeles led the climatech funding list at $544.62 million, followed by No. 2 Denver, No. 3 D.C., No. 4 Seattle, and No. 5 Houston. In 12th place was Dallas-Fort Worth ($30.55 million). Austin claimed the No. 15 spot ($13.38 million).

“While traditional coastal tech hubs still hold considerable influence, dozens of [climatech] clusters are emerging between them,” says Revolution.

In its new report on America’s top climatech hubs, Revolution cites three Houston startups to watch:

  • Buildforce, a platform for workers in the electrical trades
  • Fervo Energy, a supplier of carbon-free energy through geothermal projects
  • Solugen, a developer of bio-based chemicals that replace traditional petroleum-based products

Houston-based Solugen named among annual top disruptors

on the rise

Houston-based biotech startup Solugen is making waves among innovative companies.

Solugen appears at No. 36 on CNBC’s annual Disruptor 50 list, which highlights private companies that are “upending the classic definition of disruption.” Privately owned startups founded after January 1, 2009, were eligible for the Disruptor 50 list.

Founded in 2016, Solugen replaces petroleum-based products with plant-derived substitutes through its Bioforge manufacturing platform. For example, it uses engineered enzymes and metal catalysts to convert feedstocks like sugar into chemicals that have traditionally been made from fossil fuels, such as petroleum and natural gas.

Solugen has raised $643 million in funding and now boasts a valuation of $2.2 billion.

“Sparked by a chance medical school poker game conversation in 2016, Solugen evolved from prototype to physical asset in five years, and production hit commercial scale shortly thereafter,” says CNBC.

Solugen co-founders Gaurab Chakrabarti and Sean Hunt received the Entrepreneur of The Year 2023 National Award, presented by professional services giant EY.

“Solugen is a textbook startup launched by two partners with $10,000 in seed money that is revolutionizing the chemical refining industry. The innovation-driven company is tackling impactful, life-changing issues important to the planet,” Entrepreneur of The Year judges wrote.

In April 2024, Solugen broke ground on a Bioforge biomanufacturing plant in Marshall, Minnesota. The 500,000-square-foot, 34-acre facility arose through a Solugen partnership with ADM. Chicago-based ADM produces agricultural products, commodities, and ingredients. The plant is expected to open in the fall of 2025.

“Solugen’s … technology is a transformative force in sustainable chemical manufacturing,” says Hunt. “The new facility will significantly increase our existing capabilities, enabling us to expand the market share of low-carbon chemistries.”

Houston’s Gaurab Chakrabarti and Sean Hunt, the founders of the transformative chemical manufacturing company Solugen, have been named EY’s US National Award winners for Entrepreneur of the Year.

Solugen, also recently named a finalist in the 2023 Houston Innovation Awards, is an environmentally friendly approach that relies on smaller chemical refineries that helps in reducing costs and transportation-related emissions.

Some of their noted accomplishments includes innovations like the proprietary reactor, dubbed the Bioforge, which is a carbon-negative molecule factory and manufacturing process produces zero wastewater or emissions compared with traditional petrochemical refineries.The Bioforge uses a chemienzymatic process in converting plant-sourced substances into essential materials that can be used instead of fossil fuels.

Chakrabarti and Hunt were originally named regional winners in this year's competition this summer along with nine other Houston entrepreneurs.

Founded in 2016 by Hunt and Gaurab Chakrabarti, Solugen has raised over $600 million from investors like Sasol that believe in the technology's potential. The company is valued at reportedly over $2 billion. Solugen is headquartered in Houston, not because it is the hometown of Chakrabarti, but for what Houston brings to the company.

“There’s no way our business could succeed in the Bay Area," Chakrabarti said in a 2023 interview at SXSW where he detailed the offers Hunt and he received to move the business out of state. “For our business, if you look at the density of chemical engineers, the density of our potential customers, and the density of people who know how to do enzyme engineering, Houston happened to be that perfect trifecta for us.”

Even though they are headquartered in Houston, Solugen recently secured plans to expand to the Midwest, as in November they announced its newest strategic partnership with sustainable solutions company ADM (NYSE:ADM) in Marshall, Minnesota. The partnership includes plans for Solugen to build a 500,000-square-foot biomanufacturing facility next to an existing ADM facility , with the two companies working together on producing biomaterials to replace fossil fuel products.

“The strategic partnership with ADM will allow Solugen to bring our chemienzymatic process to a commercial scale and meet existing customer demand for our high-performance, cost-competitive, sustainable products,” Chakrabarti said in a news release. “As one of the few scaled-up and de-risked biomanufacturing assets in the country, Solugen’s Bioforge platform is helping bolster domestic capabilities and supply chains that are critical in ensuring the U.S. reaches its ambitious climate targets.”

For Chakrabarti and Hunt, Solugen was born out of a 12-year friendship, and the journey began after a friendly card game. After an entrepreneurship contest at MIT, which earned them second place and a $10,000 prize, they invested the winnings to work on what would become Solugen, a proof-of-concept reactor with materials bought from a local home improvement store.

"We had a conviction that we were building something that could be impactful to the rest of the world,” Chakrabarti said at SXSW in 2023.

Solidec secures pre-seed funding from Houston VC firm

fresh funding

Houston-based Flathead Forge Fund 1 has invested in Houston startup Solidec, which specializes in modular onsite chemical manufacturing.

The investment was part of Solidec’s recent round of more than $2 million in pre-seed funding. The amount of Flathead Forge’s investment wasn’t disclosed.

“Flathead Forge brings exactly the kind of domain-specific capital and operational network that a company at our stage needs. Their focus on water and critical minerals makes this a genuinely strategic relationship,” Ryan DuChanois, co-founder and CEO of Solidec, said in a news release.

Other investors in the round included New Climate Ventures, Collaborative Fund, Echo River Capital, Ecosphere Ventures, Plug and Play Ventures, Safar Partners and Semilla Climate Capital.

Solidec produces industrial chemicals, including hydrogen peroxide, formic acid and acetic acid, using only air, water and electricity. Its modular reactors eliminate the need for energy-intensive production and long-haul distribution.

“Solidec’s platform cuts cost, emissions, and supply-chain fragility at the source,” Douglas Lee, managing director of Flathead Forge, added in the statement.

DuChanois said in an email that the company plans to use the funding to "scale (its) modular chemical manufacturing platform."

Solidec recently announced a pilot project with Lynas Rare Earths, the world’s only commercial producer of separated light and heavy rare earth oxides outside China, for production of hydrogen peroxide for a Lynas facility in Australia.

Solidec, a member of Greentown Labs Houston, spun out of associate professor Haotian Wang’s lab at Rice University in 2024. Wang focuses on developing new materials and technology for energy and environmental uses, such as energy storage and green synthesis.

Greentown Labs names new COO, appoints new Head of Houston

new leaders

Greentown Labs has reshuffled its leadership, elevating Houston leaders into new roles.

Lawson Gow was named COO of the Houston- and Boston-based climatech incubator in February 2026. In his new role, he will focus on optimizing Greentown's structure, building new internal and external systems and developing a plan for growth.

Gow was named Head of Houston in July. He previously founded The Cannon, a coworking space with eight locations in the Houston area, with additional partner spaces. He also recently served as managing partner at Houston-based investment and advisory firm Helium Capital. Gow is the son of David Gow, founder of Energy Capital's parent company, Gow Media.

Kelsey Kearns, who previously served as Director of Community Strategy at Greentown, was named as Gow's replacement in the Houston-focused role. As the new Head of Houston, she will lead daily operations, work to connect the city's climate and innovation ecosystem and founders, strengthen partnerships and accelerate solutions.

"I'm honored and grateful to step into this new role," Kearns said in an email. "My goal is for Greentown to thrive so our founders can thrive! That means supporting their connection to the capital, pilots, and customers they need to grow while building partnerships across Houston's innovation ecosystem. I want Greentown Houston to become the playbook for every future Greentown expansion."

Before joining Greentown Houston, Kearns served as director of business development at Howdy.com, an Austin-based technology staffing company.

"Kelsey is such a perfect fit to lead Greentown Houston," Gow added in an email. "She's deeply passionate about the entrepreneurial community here and has worked throughout and across the ecosystem for years. She's built an awesome dream team here and has helped reinvigorate Greentown's presence and role in Houston's innovation economy."

Earlier this year, Greentown also named Julia Travaglini as the Head of its Boston incubator. Travaglini has held multiple leadership roles at Greentown since 2016. The organization named Georgina Campbell Flatter as its new CEO in early 2025.

Texas sees 5th highest surge in gas prices in the U.S. since 2025

Pay at the Pump

Residents all around Texas are seeing soaring prices for regular and diesel fuel in 2026.

In fact, the Lone Star State has seen the fifth-highest percentage increase in gas prices in the country from April 2025 to April 2026, a just-released SmartAsset study has found. The current cost of a regular gallon of gas is 36.1 percent higher now than it was a year ago, and diesel is 60.9 percent more expensive.

The report, "Gas Prices Hit Records in 2026: State by State Breakdown," compared average gas prices from AAA from April 1, 2025 and April 1, 2026 and calculated the one-year change across all 50 states. The study looked at the price of a gallon of regular, premium, and diesel.

According to AAA, the cost of a regular gallon of gas in Texas at the start of April was $3.77, while premium is $4.62 per gallon. Diesel ticked over $5 a gallon — ouch — at $5.11.

Houston gas prices aren't much cheaper than the statewide average. A gallon of regular costs up to $3.76 at some Houston-area pumps, and diesel is $5.05 per gallon. AAA says the highest recorded average price for gas in the city was in June 2022, when a gallon of regular cost $4.68 and diesel cost $5.24.

Though Texas' gas prices are continuing to climb, it ranks 35th in the national ranking of states with the highest cost for regular gas as of April 2026. Texas' diesel prices are the 14th highest nationwide.

With the national average price for gas at $4.06, SmartAsset said the sudden surge in prices can be attributed to the United States' war on Iran, and "subsequent pressure on the Strait of Hormuz."

"Many states have experienced a 33 percent year-over-year increase in the cost of a gallon of regular gas – and in some places it’s even higher," the report's author wrote. "Commercial and public programs may be feeling similarly pinched, with diesel prices upwards of $6.00 per gallon in many states."

California currently has the highest average price for regular and diesel — $5.89 per gallon and $7.52 per gallon, respectively.

Arizona leads the nation with the highest one-year increase in gas prices. Regular gas in the Grand Canyon State is nearly 38 percent more expensive than it was last year, at $4.70 per gallon, and diesel is about 69 percent higher at $6.04 for a gallon.

The state with the cheapest gas prices in April is Oklahoma, where regular costs $3.27 per gallon, premium is $3.97, and diesel is $4.49.
