Anning Corporation

Clean energy company Anning Corporation is working to develop geologic hydrogen, a natural carbon-free fuel, using its proprietary stimulation approaches and advanced exploration modeling. The company said that geologic hydrogen has the potential to be the lowest-cost source of reliable baseload electricity in the U.S.

The company was founded by CEO Sophie Broun in 2024 and is a member of Greentown Labs. Last month, it also announced that it was chosen to participate in Breakthrough Energy’s prestigious Fellows Program. Anning raised a pre-seed round this year and is currently raising a $6 million seed round.

Capwell Services

Houston-based 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 current CEO Andrew Lane. It has since participated in programs with Greentown Labs and Rice Clean Energy Accelerator. The company moved to Houston in 2023 and raised a pre-seed round. It has also received federal funding from the DOE. Capwell is currently piloting its commercial unit with oil and gas operators.

Deep Anchor Solutions

Offshore energy consulting and design company Deep Anchor Solutions aims to help expedite the adoption of floating offshore energy infrastructure with its deeply embedded ring anchor (DERA) technology. According to the company, its patented DERA system can be installed quietly without heavy-lift vessels, reducing anchor-related costs by up to 75 percent and lifecycle CO2 emissions by up to 80 percent.

The company was founded in 2023 by current CEO Junho Lee and CTO Charles Aubeny. Lee earned his Ph.D. in geotechnical engineering from Texas A&M University, where Aubeny is a professor of civil and environmental engineering. The company has participated in numerous accelerators and incubators, including Greentown Labs, MassChallenge, EnergyTech Nexus LiftOff, and others. Lee is an Activate 2025 fellow.

Eclipse Energy

Previously known as Gold H2, Eclipse Energy converts end-of-life oil fields into low-cost, sustainable hydrogen sources. It completed its first field trial this summer, which demonstrated subsurface bio-stimulated hydrogen production. According to the company, its technology could yield up to 250 billion kilograms of low-carbon hydrogen, which is estimated to provide enough clean power to Los Angeles for over 50 years and avoid roughly 1 billion metric tons of CO2 equivalent.

Eclipse was founded in 2022 by Moji Karimi (CEO and chairman of Cemvita), Prabhdeep Sekhon (CEO of Eclipse), Tara Karimi, and Rayyan Islam. The company closed an $8 million series A this year and has plans to raise another round in 2026.

Loop Bioproducts

Agricultural chemical manufacturing company Loop Bioproducts leverages the physiology of prickly pear cactus grown in Texas to produce bioenergy, food, and remediate industrial wastewater streams. The company uses its remote sensing technology, proprietary image-based machine learning model, and R&D innovation to capture raw biogas from the cactuses and is focused on scaling cactuses as an industrial crop on land.

Rhiannon Parker founded Loop Bioproducts in 2023.

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. The company reports that it plans to open its first commercial plant in the next 18 months.

Founded in 2019 by CEO Aaron Fitzgerald, CTO Kristian Gubsch, and lead engineer Trey Sheridan, the company has raised just under $1 million in capital and is backed by Bill Gates’ Breakthrough Energy, Shell, Black & Veatch, and other organizations.

Solidec

Chemical manufacturing company Solidec has developed autonomous generators that extract molecules from water and air and converts them into pure chemicals and fuels that are free of carbon emissions onsite, 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 chief scientist, CEO Ryan DuChanois, and CTO Yang Xia. It closed a $2.5 million seed round earlier this year.

Houston named the No.1 emerging city for biopharma in inaugural report

Biopharma Leader

Houston is ranked No.1 on the first-ever Next 10 U.S. Biopharma Clusters report published by Genetic Engineering & Biotechnology News (GEN).

The report, which ranks the best emerging hubs for life science activities, considered patents, NIH funding, lab space, venture capital investments, and the number of jobs in regions in cities, states and “clusters” across the U.S. GEN touts Houston as the top city for the biopharma industry due to a surge in funding, job creation, medical innovations and startup success.

Here’s how Houston ranked in the report’s different categories;

  • No. 1 for NIH funding with 2,262 awards totaling more than $1.25 billion
  • No. 2 for emerging regions for jobs, with 28,000 jobs
  • No. 2 for lab space, with roughly 8 million square feet in the market
  • No. 6 for patents, with 2,760 patent families

According to BioHouston chairman Jeff Wade, Houston secured half a billion dollars in venture capital funding in 2025 and 2026 to date.

The report called out major biopharm news out of Houston in the last few months, including Bristol Myers Squibb selecting Houston for its $1 billion, 600,000-square-foot manufacturing site and Eli Lily selecting Houston for its $6.5 billion, 236-acre manufacturing site. Both facilities will be located within Generation Park, a 4,300-acre, master-planned commercial district near Lake Houston.

Houston startups like CrossBridge Bio and Duracyte were also mentioned in the report. CrossBridge, which develops antibody-drug conjugates for cancer, was acquired by Eli Lily in April for $300 million. Duracyte, a “living pharmacy” company, was launched out of Rice University’s biotech venture studio RBL LLC this spring and is backed by up to a $45 million Advanced Research Projects Agency for Health (ARPA-H) award.

The startup is working to commercialize its Hybrid Advanced Molecular Manufacturing Regulator (HAMMR) technology, a rechargeable, implantable device that can sense biological signals, monitor tumor environments and adjust therapeutic output in real time.

“There’s a lot of great talent, but the unique advantage that we have is we are able to benefit from a lot of unique clinical infrastructure and clinician insights,” Omid Veiseh, Duracyte co-founder and managing partner of RBL LLC, told GEN. “There are a lot of clinicians here who are eager to partner on investigator-initiated trials.”

The report also touted Houston’s Texas Medical Center, home to the University of Texas MD Anderson Cancer Center and Baylor College of Medicine, and international partnerships like the recently expanded TMC Korea BioBridge.

Other cities to make the list include:

  • No. 2 Minneapolis-St. Paul
  • No. 3 Denver-Boulder
  • No. 4 St. Louis
  • No. 5 Dallas-Fort Worth

States to make the list include:

  • No. 1 Ohio (including Cincinnati, Cleveland, and Columbus)
  • No. 2 Indiana (including Indianapolis)
  • No. 3 Florida (including Jacksonville and Miami-Fort Lauderdale)
  • No. 4 Georgia (including Atlanta and Augusta)
  • No. 5 Wisconsin (including Madison and Kenosha)

Regional state clusters to watch include:

  • Phoenix
  • Pittsburgh
  • Greater Richmond, Virginia

Major Texas-based airlines ground humanoid robots as passengers

In The Air

Two major airlines based in Texas are drawing a hard line between human and humanoid: American Airlines and Southwest Airlines won’t permit human-like or animal-like robots to board flights as passengers.

Fort Worth-based American and Dallas-based Southwest recently adopted bans on robotic passengers after two incidents in which human-like robots joined flesh-and-blood passengers on Southwest flights.

In May, Aaron Mehdizadeh, owner of The Robot Studio rental company in Dallas, was heading from Las Vegas to Dallas Love Field with 3.5-foot-tall Stewie, according to CBS News Texas. Rather than shipping Stewie as cargo, Mehdizadeh bought the robot its own seat using a type of ticket often purchased for fragile items such as wedding dresses and equipment.

But because Stewie was technically a carry-on item, the robot wasn’t supposed to occupy a seat, according to eWeek. Crew members wound up disconnecting Stewie’s battery and relocating the robot to a window seat before takeoff.

Mehdizadeh pushed back on Southwest’s stance regarding the battery, telling CBS News Texas that Stewie’s power supply is a standard battery that’s similar to one for a laptop.

Stewie isn’t the only robot making mischief in the skies. In May, a 70-pound, human-like robot named Bebop caused a stir on a Southwest flight from Oakland, California, to San Diego.

The robot prompted a nearly one-hour flight delay after crew members realized it violated restrictions on large carry-ons and raised concerns about the battery, San Francisco TV station KGO reported. Dallas-based Elite Event Robotics owns Bebop.

Southwest seized Bebop’s lithium-ion battery, but the airline did let Bebop take the San Diego-bound flight.

Southwest’s new robot policy prohibits human-like or animal-like robots from riding in an airplane cabin or as checked baggage, no matter their size or purpose. All other robots, including toys, must fit in a carry-on size bag and comply with battery restrictions, the airline says.

In a statement sent to CultureMap, a Southwest spokeswoman says the airline “has taken a strong stance on this issue and has led the U.S. airline industry with our battery policy.”

“The robot policy is a further evolution of a [safety] journey we have been on for several months. This move was not in response to any single incident,” the spokeswoman adds. “To eliminate confusion, the policy applies to all similar devices, regardless of size.”

Lithium-ion batteries can overheat, catch on fire, or explode on airplanes.

American’s new robot policy, which took effect Monday, August 17, is similar to Southwest’s. The policy prohibits human-like and animal-like robots from sitting in a purchased seat, being stored in an overhead bin or traveling as checked baggage. The ban applies to U.S., international, and regional flights.

“While there have been no known events involving this type of robot on any American flight, this policy was developed following a comprehensive review of safety risks associated with these devices, including the large lithium-ion batteries that power them,” the airline said in an internal memo obtained by the View From the Wing travel blog.

American gate agents have been told not to allow a passenger accompanied by a robot to board a plane or to let a robot travel as a checked item, the memo say.

If a robot is discovered after check-in, American employees are supposed to follow the Federal Aviation Administration’s “undeclared dangerous goods” procedures. These procedures cover hazardous shipments like lithium-ion batteries, explosives, flammable liquids, and compressed gases that lack required warning labels or shipping documents.

Texas A&M, UH rise in global rankings of universities attracting the most attention

visibility report

Houston and Texas universities had a strong showing on the 2026-27 Global University Visibility (GUV) Rankings compiled by D.C.-based higher ed market research firm American Caldwell.

Texas A&M ranked No. 6 on the list—the top rank of any Texas university. Meanwhile, the University of Houston ranked No. 52, a 15-spot jump from its previous ranking.

The GUV rankings rate colleges that garner the most global attention via news coverage, social media influence, website traffic, YouTube views, and general public interest. GUV evaluated over 1,200 universities across 193 United Nations-recognized countries.

Texas A&M, with its No. 6 global ranking, also claimed the No. 5 spot among U.S. institutions. The university climbed 21 spots from its previous rank.

“News mentions were a driver of Texas A&M’s movement in this year’s rankings, and earned media remains one of the strongest signals of relevance,” Tim Doty, associate vice president for earned media at Texas A&M, said in a news release. “Much of that visibility begins with our faculty and research experts, whose work helps explain, solve and give context to issues people care about. When Texas A&M experts appear in news stories about research, discovery, national security, agriculture, health, engineering, service and the future of Texas, audiences see the university not only as large or well known, but as useful, relevant and necessary to the conversations shaping our state and country.”

In the “Public Interest” category, UH also claimed a top 10 global ranking at No.6. UH touts its overall GUV rankings success to Guggenheim Fellowships, MacArthur “Genius” grants, National Academy membership, studies like researchers breaking the superconductivity temperature record, and success on the football field and basketball courts.

“Across the board, there is no question that the University of Houston is a brand on the rise,” Shawn Lindsey, interim vice president for marketing and communications, said in a news release. “People are seeing our story, hearing about the amazing things happening at UH and actively seeking us out to learn more. We are seeing it in record-high student applications, we are seeing increases in trademark licensing revenue, our faculty are earning global accolades. It’s an exciting time to be a Houston Cougar.”

Other Texas institutions to make the top 250 on the list include:

  • No. 22 The University of Texas at Austin
  • No. 104 University of Texas at Dallas
  • No. 159 Texas Tech University
  • No. 178 Rice University
  • No. 191 University of North Texas
  • No. 248 Texas State University

For the fourth year in a row, Harvard University secured the top spot on the list, followed by MIT, Stanford University and Purdue University. The University of Oxford was the top non-U.S. institution at No. 5.
