Houston is home to a growing number of startups reshaping what it means to be called the "Energy Capital of the World."

As part of the 2026 Houston Innovation Awards, our Energy Transition Business category honors those innovative startups that are providing solutions within renewables, climatetech, clean energy, alternative materials, circular economy and more.

Five clean energy startups have been named finalists for the 2026 award. The finalists, selected by our esteemed panel of judges, range from a lower-emission steel producer to a diagnostics platform developer working to support batteries used in data centers.

Read more about these innovative businesses, their initiatives, and their inspirational founders below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Capwell Services

Methane capture company Capwell Services works to eliminate vented oil and gas emissions economically for operators. According to the company, methane emissions are vented from most oil and gas facilities due to safety protocols, and operators are not able to capture the gas cost-effectively, leading operators to emit more than 14 million metric tons of methane per year in the U.S. and Canada. Founded in 2022, Capwell specializes in low and intermittent flow vents for methane capture.

The company began as a University of Pennsylvania senior design project led by CEO Andrew Lane. It has since participated in programs with Greentown Labs, the Rice Clean Energy Accelerator and the Creative Destruction Lab Energy Cohort at Texas A&M University. The company moved to Houston in 2023 and raised a pre-seed round. It deployed two commercial units this year, according to its application.

FlowCellutions

Energytech startup FlowCellutions is developing a chemistry-agnostic diagnostics platform for flow and metal-air batteries supporting data centers and critical infrastructure. The platform is designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from approximately seven years to more than 30 years. It has deployed four paid pilots and plans to take insights from the programs to develop its next-gen sensor platform technology.

CEO Becca Segel founded the company in 2022. It is a member of Greentown Labs, and Segel was a 2025 Activate Fellow. The company has raised over $2 million in non-dilutive funding and received a $1.5 million NSF SBIR Fast-Track award earlier this year.

Hertha Metals

Hertha Metals produces lower-cost, lower-emission steel and high-purity iron. The company has developed a single-step process that uses natural gas as a direct reductant instead of metallurgical coal, which cuts production costs by more than 25 percent and emissions by up to 50 percent, according to the company. The same process produces high-purity iron needed for high-purity steels and rare earth magnets. The company says it aims to "re-industrialize America’s production of critical materials."

Hertha Metals was founded by CEO Laureen Meroueh in 2022 and emerged from stealth last year with more than $17 million in venture capital funding. The company closed a $133.65 million Series A this month and also broke ground on its $100M high-purity iron factory known as Chalyx in Conroe.

Mars Materials

Clean chemical manufacturing business Mars Materials is working to convert captured carbon into resources, such as carbon fiber and wastewater treatment chemicals. The company develops and produces its drop-in chemical products in Houston and uses an in-licensed process for the National Renewable Energy Lab to produce acrylonitrile, which is used to produce plastics, synthetic fibers, and rubbers.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and vice president of operations Trey Sheridan, the company has secured over $7.2M in financing and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations. It won in the Minority-founded Business Category in last year's Houston Innovation Awards.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and convert them into pure chemicals and fuels that are free of carbon emissions on-site, eliminating the need for transport, storage, and permitting. The company was founded around innovations developed by Rice University associate professor Haotian Wang.

The company was selected for the Chevron Technology Ventures’ Catalyst Program, Greentown Labs, NSF I-Corps and was part of the first cohort of the Activate Houston program. It won first place at the 2024 startup pitch competition at CERAWeek. Solidec was founded in 2023 by Wang, who serves as an advisor, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round in 2025.

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.

Solidec partners with Australian company for clean hydrogen peroxide pilot​

rare earth pilot

Solidec has partnered with Australia-based Lynas Rare Earth, an environmentally responsible producer of rare earth oxides and materials, to reduce emissions from hydrogen peroxide production.

The partnership marks a milestone for the Houston-based clean chemical manufacturing startup, as it would allow the company to accelerate the commercialization of its hydrogen peroxide generation technology, according to a news release.

"This collaboration is a major milestone for Solidec and a catalyst for sustainability in rare earths," Yang Xia, co-founder and CTO of Solidec, said in the release. "Solidec's technology can reduce the carbon footprint of hydrogen peroxide production by up to 90%. By combining our generators with the scale of a global leader in rare earths, we can contribute to a more secure, sustainable supply of critical minerals."

Through the partnership, Solidec will launch a pilot program of its autonomous, on-site generators at Lynas's facility in Australia. Solidec's generators extract molecules from water and air and convert them into carbon emission-free chemicals and fuels, like hydrogen peroxide. The generators also eliminate the need for transport, storage and permitting, making for a simpler, more efficient process for producing hydrogen peroxide than the traditional anthraquinone process.

"Hydrogen peroxide is essential to rare earth production, yet centralized manufacturing adds cost and complexity," Ryan DuChanois, co-founder and CEO of Solidec, added in the release. "By generating peroxide directly on-site, we're reinventing the chemical supply chain for efficiency, resilience, and sustainability."

The companies report that the pilot is expected to generate 10 tons of hydrogen peroxide per year.

If successful, the pilot would serve as a model for large-scale deployments of Solidec's generators across Lynas' operations—and would have major implications for the high-performance magnet, electric vehicles, wind turbine, and advanced electronics industries, which rely on rare earth elements.

"This partnership with Solidec is another milestone on the path to achieving our Towards 2030 vision," Luke Darbyshire, general manager of R&I at Lynas, added. "Working with Solidec allows us to establish transformative chemical supply pathways that align with our innovation efforts, while contributing to our broader vision for secure, sustainable rare earth supply chains."

Houston clean-chemicals startup Solidec raises $2M to scale tech

fresh funding

Solidec, a Houston startup that specializes in manufacturing “clean” chemicals, has raised more than $2 million in pre-seed funding.

Houston-based New Climate Ventures led the oversubscribed pre-seed round, with participation from Plug and Play Ventures, Ecosphere Ventures, the Collaborative Fund, Safar Partners, Echo River Capital and Semilla Climate Capital, among other investors.

Solidec’s approach to chemical manufacturing replaces centralized infrastructure with modular on-site production using only air, water and electricity. Solidec’s platform is powered by modular reactors capable of producing widely used chemicals such as hydrogen peroxide, formic acid, acetic acid and ethylene.

“We’ve known the Solidec team for almost two years and have developed a high degree of conviction in the team, their technology, and their go-to-market strategy,” Eric Rubenstein, managing partner at New Climate Ventures, said in a news release. “We’re particularly excited about Solidec’s ability to produce many different widely used chemicals. It gives them critical flexibility to expand and serve a broad customer base.”

Solidec is initially focusing on hydrogen peroxide.

“Traditionally, hydrogen peroxide is produced in centralized, energy-intensive facilities using carbon-intensive inputs, then transported long distances, resulting in a significant carbon footprint,” Ryan DuChanois, co-founder and CEO of Solidec, said in the release. “Solidec’s modular reactor produces clean chemicals like hydrogen peroxide on-site, in fewer steps, and with less energy, slashing emissions, supply-chain risk, and cost.”

Solidec said its technology “is poised to disrupt the multibillion-dollar commodity and chemical industries.” The company has already signed up several customers.

The startup, a Rice University spinout, is a graduate of the Chevron Catalyst Program and a member of Greentown Labs Houston. It was cofounded by DuChanois, Haotian Wang and Yang Xia.

Houston researchers win prestigious DOE early career awards

Researchers at Rice University, the University of Houston and other Texas universities have been awarded the Department of Energy’s Early Career Award for their work in quantum science, AI and more.

Each professor who received the honor will be awarded $875,000 over five years to continue their work.

The Houston-area recipients include:

  • James Shee, assistant professor of chemistry at Rice University
  • Tony Geng, assistant professor of electrical and computer engineering at Rice
  • Naihao Chiang, assistant professor in the department of chemistry at the University of Houston

For Shee, the award will support his work to advance a “first principles platform to simulate the quantum dynamics of chemical systems of relevance to sustainable energy consumption and generation,” according to a news release from Rice.

“Support from the Department of Energy will enable my group to pursue the ambitious quantum chemistry development required to simulate the dynamics of transition metal-based molecular computing paradigms and multi-excitonic processes in a purely ab initio manner,” Shee said in the release.

Geng is developing next-generation AI for real-time digital twins for scientific systems. Geng and his team will make microchips that function as trainable electronic dynamical systems computing through natural, continuous evolution rather than digital instructions, according to the university.

Chiang’s work at UH addresses the DOE’s Quantum Information Science priority. Chiang leads a team that develops and applies “plasmonic-enhanced near-field optical techniques” to investigate fundamental light-matter interactions at the quantum limit before applying them to emerging technologies. In addition, the team will use AI to help with data acquisition and will utilize STEM workforce development.

Dr. Joshua Burby, an assistant professor in the Department of Physics at the University of Texas at Austin, and Junyeong Ahn, who is part of the University’s Texas Quantum Institute, also received early career awards for their work in superconducting and fusion technologies. See the full list of recipients from around the country here.

“The energy and creativity of early-career scientists is crucial for propelling scientific discovery forward. The Department of Energy is committed to nurturing this talent through programs like the Early Career Research Program,” Darío Gil, DOE under secretary for science, added in a release. “These awards provide essential resources and opportunities for collaboration, enabling these researchers to explore novel concepts and accelerate the development of solutions for our nation’s energy and scientific landscape.”

The DOE has also doled out funding to Houston researchers and companies in recent months through its Genesis Mission and geothermal initiatives.

Researchers from Rice, UH and Halliburton were named in July among the nearly 300 projects selected under the Trump administration's Genesis Mission, which aims to address some of the largest science and technology challenges in the country

In September, three Houston companies also received more than $45 million in funding from the DOE's Next-Generation Geothermal Field Tests and Geothermal Resource Characterization and Confirmation initiative to advance geothermal technologies and field tests. The projects were among 21 selected from around the country to receive a total of $99 million. Read more here.

Elon Musk's Tesla to cease cybertruck production in 2027

Tesla Talk

Tesla’s Cybertruck, the hulking, stainless-steel pickup that inspired devotion and derision with its science-fiction looks, will cease production next year.

CEO Elon Musk announced the model’s demise Friday, November 6, with a curt post on X, his social media site, simply noting production of the vehicle “will be winding down” around the middle of 2027 at its facility outside Austin, Texas. Musk said the move was to allow increased production of its Cybercab robotaxi.

For the Cybertruck, a pet project of Musk who insisted it was Tesla’s best product, it marks an unceremonious end to one of the auto industry’s most ballyhooed debuts.

“Few vehicles in history have generated as much attention,” said Armen Hareyan, whose Torque News site covers autos. “The Cybertruck became a cultural symbol – loved, mocked and impossible to ignore.”

The Cybertruck rolled onto the scene in a dramatic unveiling in 2019, when a Tesla designer hurled a metal ball at the vehicle to demonstrate its supposedly unbreakable glass, only to see it shatter. He repeated the stunt on another window of the truck only to shatter that one, too.

Even as some critics scoffed, Musk was steadfast.

“I just wanted to make a futuristic battle tank — something that looks like it could come out of ‘Blade Runner’ or ‘Aliens’ or something like that but was also highly functional,” he told Automotive News. He called it “a better sports car than a Porsche 911” and “a better truck than an F-150.”

It struck some as the perfect vehicular reflection of the brash, convention-busting Musk.

“A really controversial vehicle unveiled by a controversial individual into a market where none of the electric trucks have been able to really capture demand,” said Spencer Penn, a former Tesla executive who left the company before the Cybertruck’s launch and now heads software developer LightSource.

Penn remembered watching the unveiling and feeling initially revolted by the sight of the Cybertruck, calling its appearance “madness.” But the more he looked at it, the more his opinion changed. He signed up for a pre-sale reservation, though ended up not getting a Cybertruck when Musk’s promises of a price tag under $40,000 went unmet and the first trucks sold for double or more. Penn called the Cybertruck part of Tesla’s adventurous spirit that drives innovation.

“Some of these bets work and some of these bets don’t,” he said.

While the decision to end Cybertruck production may be driven by sales realities, it's also a reflection of Tesla’s shift to autonomous vehicles, on which Musk is betting the company’s future.

Musk once forecast he’d make 250,000 Cybertrucks a year. Kelley Blue Book estimated Tesla sold just 20,237 of the vehicles last year, down about half from the year prior. Sales through the end of September this year were down another 28%, according to Kelley Blue Book.

If the imposing, sharp-angled, dystopian appearance of the Cybertruck weren’t enough to turn many potential buyers away, Musk did so himself by allying with a panoply of right-wing figures, most notably U.S. President Donald Trump. He alienated some customers as his image morphed from eccentric innovator to polarizing force trading his billions for political influence.

Once-passionate Tesla drivers rushed to sell off their cars, or slapped stickers on the bumper declaring, “I bought this before Elon went crazy.” Organizers staged demonstrations outside Tesla showrooms and urged investors to dump shares of the company’s stock. Anger spilled into violence, with Molotov cocktails hurled at Tesla vehicles, charging stations set ablaze, and dealerships covered in graffiti.

Lovers of the Cybertruck became targets, too, subjected to shouts of “Nazi!” and extended middle fingers.

Ross Blankenship is one of them. When he first laid eyes on the Cybertruck, he felt transported to a world from his childhood, when he would play “Halo,” the sci-fi video game. He had to have it.

“I had that sort of child in me wanting to be part of something cool that would change the future of automotive,” Blankenship said in a call from his Cybertruck as he drove through Sunnyside, Colorado. Even as Blankenship found he agreed with Musk on politics, he hated seeing a vehicle he loved turned into a political symbol. “I never bought it for any other reason than the fascination with the future technology of trucks … so that was a little heartbreaking.”

He would buy another Cybertruck again in a heartbeat, calling its end “a sad moment.”

In addition to Tesla’s $200 million megafactory in Brookshire, Texas, the electric vehicle company is also considering building a $10.1 billion solar cell manufacturing facility in Fort Bend County called Project Sun City. The company recently expanded its self-driving Robotaxi service throughout 610 Loop and northwest Houston.

A second grant of $690,044 will go toward training 300 workers at Texas Tissue LLC and Karsten Management LLC as frontline supervisors, production line operators, design specialists and maintenance technicians. An allocation of $83,963 will go toward training 41 workers at Watchfire Signs LLC as production supervisors, operations specialists, industrial maintenance technicians, and more.

According to HCC, its Corporate Training and Development will coordinate the program in partnership with the college’s Advanced Manufacturing Center of Excellence Southwest and the Material Science Center of Excellence Welding Department.

“These grants demonstrate how state agencies, employers and Houston City College can work together to meet evolving workforce needs, strengthen Texas businesses and create meaningful opportunities for workers,” HCC Chancellor Margaret Ford Fisher said in a news release.

TWC granted an additional $169,087 to Workforce Solutions Lower Rio Grande Valley to train 87 workers at Denso Ten America Limited, Alps Logistics (USA) Inc., Index Fresh Inc. and Emerson Electric Co.

“When we align local training directly with the needs of expanding industries, we strengthen the regional economy,” TWC Chairman Joe Esparza said in the news release. “These Skills Development Fund grants empower Houston City College and Workforce Solutions Lower Rio Grande Valley to provide the specialized, high-demand training that employers need to succeed right here in Texas.”
