Houston energy hub announces first cohort for new accelerator

green team

Energytech Nexus, a Houston-based hub for energy startups, has named its inaugural cohort of 14 companies for the new COPILOT accelerator.

COPILOT partners with Browning the Green Space, a nonprofit that promotes diversity, equity and inclusion (DEI) in the clean energy and climatech sectors. The Wells Fargo Innovation Incubator (IN²) at the National Renewable Energy Laboratory backs the COPILOT accelerator.

The eight-month COPILOT program offers mentorship, training and networking for startups. Program participants will be tasked with developing pilot projects for their innovations.

Two Houston startups are members of the first COPILOT class:

  • GeoFuels, housed at Houston’s Greentown Labs, has come up with a novel approach to hydrogen production that relies on geothermal power and methane decomposition.
  • PolyQor, which converts plastic waste into eco-friendly construction materials. Its flagship EcoGrete product is an additive for concrete that enhances its properties while reducing carbon emissions. PolyQor’s headquarters is at Houston’s Greentown Labs.

Other members of the COPILOT cohort are:

  • Birmingham, Alabama-based Accelerate Wind, developer of a wind turbine for commercial buildings.
  • Ann Arbor, Michigan-based Aquora Biosystems, which specializes in organic waste biorefineries.
  • Phoenix-based EarthEn Energy, a developer of technology for thermo-mechanical energy storage.
  • New York City-based Electromaim, which installs small hydro-generators in buildings’ water systems.
  • Chandler, Arizona-based EnKoat, an advanced materials company whose flagship product, the IntelliKoat System, is a patented two-layer thermal and weather barrier roof coating for flat and low-slope commercial buildings.
  • Calgary, Canada-based Harber Coatings, which manufactures electroless nickel coating and electroless nickel plating.
  • Dallas-based Janta Power, which designs and makes 3D solar towers.
  • Miami-based NanoSieve, a developer of gas remediation technology.
  • Palo Alto, California-based Popper Power, which has developed a platform that turns streetlight networks into resilient, maintenance-free distributed charging infrastructure.
  • Buffalo, New York-based Siva Powers America, developer of small wind turbines for farms, utility companies and others with annual energy needs of 300,000 to 2 million kilowatt-hours.
  • Los Angeles-based Thermoshade, which specializes in cooling panels for outdoor environments.
  • Waukesha, Wisconsin-based V-Glass, Inc., developer of a vacuum-insulated glass for affordable high-efficiency windows.

“These startups reflect the future of energy access and resilience innovation,” said Juliana Garaizar, founding partner of Energytech Nexus. “By connecting them directly with partners through

COPILOT, we’re helping them overcome the ‘pilot gap’ to build solutions that scale.”

The startups will run pilot projects along the Gulf Coast for their inventions.

Fervo promotes strategy leader to COO as flagship geothermal project nears launch

new leader

Houston geothermal unicorn Fervo Energy has named Sarah Jewett as its new COO.

Jewett steps into the role as the company prepares for its flagship Cape Station geothermal project to deliver its first power later this year.

Jewett joined Fervo in 2020 as director of strategy and most recently served as the company's senior vice president of strategy. She spoke with HETI on the potential of geothermal energy in 2024.

Before Fervo, Jewett served as senior director of corporate development for Houston-based Select Energy Services. She ran hydraulic fracturing crews for Schlumberger in the Permian Basin and Alaska's North Slope early in her career.

In the COO role, Jewett is tasked with creating "the centralized infrastructure required to execute on what the company believes is the most significant commercial opportunity for clean, firm power in history," according to a company release.

“What Sarah has built over the last six years has been foundational to the company’s success. From the time she joined, she has brought an unwavering people-first mindset and outstanding dedication to building things that last,” Tim Latimer, CEO and co-founder of Fervo, added in the release. “As we move into the next phase of our growth, there is no better person to lead the operating core of this company.”

Jewett holds an MBA from Harvard Business School and a bachelor's degree in mechanical engineering from Dartmouth College.

Fervo announced the addition of four heavyweights to its board of directors this spring, including Meg Whitman, former CEO of eBay, Hewlett-Packard, and Spring-based HPE. Shortly after, the company filed for its highly anticipated $1 billion-plus IPO. Read more here.

UH study finds Gulf Coast best positioned for emerging carbon removal technology

coastal impact

The Gulf Coast is an ideal spot for deploying a new ocean-based carbon removal technology that uses seawater to capture and store carbon dioxide, according to a new study from the University of Houston.

The study was led by UH Cullen College of Engineering Professor Mim Rahimi and published in Nature’s Communications Sustainability journal. Abdelrahman Refaie, a PhD student at UH, authored the paper. It aimed to develop a plan for implementing an electrochemical marine carbon dioxide removal (e-mCDR) technology that treats seawater to increase the ocean’s ability to absorb and store carbon dioxide from the air.

Currently, oceans absorb about 30 percent of human-produced carbon dioxide emissions each year, according to UH, making it a great natural resource for carbon removal.

The team at UH scouted and analyzed 38 coastal facilities across the U.S.—including power plants, desalination plants, and liquefied natural gas (LNG) terminals—before determining the Gulf Coast as an attractive option. The South Hub, or the Gulf Coast along Texas and Louisiana, ranked the top-performing area for the technology due to the industrial infrastructure, affordable electricity, hydrogen transportation and storage networks.

Other regions like California and the Northeast also scored well due to their clean energy mix and carbon removal potential, according to UH.

“The South hub has one of the highest diversity factors between power plants, desalination and LNG,” Refaie said in a news release. “That means if, logistically, down the road LNG is not open for this implementation, then we have another option in the area. It reduces the risk factor.”

UH says the findings show how companies could commercialize the technology, which could boost coastal economies.

“The question we had wasn’t technical, rather, it was logistical in regard to implementation down the road,” Rahimi said. “This would be a roadmap if a company or the government wants to utilize this technology.”

Rahimi aims to increase awareness about e-mCDR technology and its potential impact. He recently discussed the ocean-centric carbon removal work with members of Congress in March at the Carbon to Sea’s 2026 Hill Day.

“I think faculty at the University of Houston can do more of this kind of work,” Rahimi said in a separate release. “Meeting with Members of Congress gives us a chance to help policymakers better understand the science and engineering happening at our university. That kind of engagement is an important part of moving new technologies forward. It also shows how the work we do on campus can have a real impact on communities beyond the university.”
