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.

2 UH projects named finalists for $50M fund to shape future of Gulf Coast

Looking to the Future

Two University of Houston science projects have been selected as finalists for the Gulf Futures Challenge, which will award a total of $50 million to develop ideas that help benefit the Gulf Coast.

Sponsored by the National Academies of Science, Engineering and Medicine’s Gulf Coast Research Program and Lever for Change, the competition is designed to spark innovation around problems in the Gulf Coast, such as rising sea levels, pollution, energy security, and community resiliency. The two UH projects beat out 162 entries from organizations based in Alabama, Florida, Louisiana, Mississippi, and Texas.

“Being named a finalist for this highly competitive grant underscores the University of Houston’s role as a leading research institution committed to addressing the most pressing challenges facing our region,” said Claudia Neuhauser, vice president for research at UH.

“This opportunity affirms the strength of our faculty and researchers and highlights UH’s capacity to deliver innovative solutions that will ensure the long-term stability and resilience of the Gulf Coast.”

One project, spearheaded by the UH Repurposing Offshore Infrastructure for Continued Energy (ROICE) program, is studying ways to use decommissioned oil rig platforms in the Gulf of Mexico as both clean energy hydrogen power generators as well a marine habitats. There are currently thousands of such platforms in the Gulf.

The other project involves the innovative recycling of wind turbines into seawall and coastal habitats. Broken and abandoned wind turbine blades have traditionally been thought to be non-recyclable and end up taking up incredible space in landfills. Headed by a partnership between UH, Tulane University, the University of Texas Health Science Center at Houston, the city of Galveston and other organizations, this initiative could vastly reduce the waste associated with wind farm technology.

"Coastal communities face escalating threats from climate change — land erosion, structural corrosion, property damage and negative health impacts,” said Gangbing Song, Moores Professor of Mechanical and Aerospace Engineering at UH and the lead investigator for both projects.

“Leveraging the durability and anti-corrosive properties of these of decommissioned wind turbine blades, we will build coastal structures, improve green spaces and advance the resilience and health of Gulf Coast communities through integrated research, education and outreach.”

The two projects have received a development grant of $300,000 as a prize for making it to the finals. When the winner are announced in early 2026, two of the projects will net $20 million each to bring their vision to life, with the rest earning a consolation prize of $875,000, in additional project support.

In the event that UH doesn't grab the grand prize, the school's scientific innovation will earn a guaranteed $1.75 million for the betterment of the Gulf Coast.

Hobby debuts solar canopy as airport system reaches new sustainability milestone

solar solutions

Houston's William P. Hobby Airport is generating its own clean energy.

Houston Airports announced that Hobby's red garage is now home to a "solar canopy" that is producing energy at 100 percent capacity to power daily operations. The photovoltaic (PV) solar system generated more than 1.1 gigawatt-hours of electricity in testing, and is expected to produce up to 1 megawatt-hour now that it's operating at full power.

“This project is proof that sustainability can be practical, visible and directly tied to the passenger experience,” Jim Szczesniak, director of aviation for Houston Airports, said in a news release. “Passengers now park under a structure that shields their cars from the Texas sun while generating clean energy that keeps airport operations running efficiently, lowering overall peak demand electrical costs during the day and our carbon footprint. It’s a win for travelers, the city and the planet.”

The project was completed by Texas A&M Engineering Experiment Station (TEES) and CenterPoint Energy. It's part of Houston Airport's efforts to reduce carbon emissions by 40 percent over its 2019 baseline.

In a separate announcement, the airport system also shared that it recently reached Level 3 in the Airports Council International (ACI) Airport Carbon Accreditation program after reducing emissions by 19 percent in three years. This includes reductions at George Bush Intercontinental Airport (IAH), Hobby and Ellington Airport/Houston Spaceport.

The reductions have come from initiatives such as adding electric vehicles to airport fleets, upgrading airfield lighting with LED bulbs, adding smarter power systems to terminals, and improving IAH's central utility plant with more efficient equipment. Additionally, the expansion to Hobby's West Concourse and renovations at IAH Terminal B incorporate cleaner equipment and technology.

According to Houston Airports, from 2019 to 2023:

  • IAH reduced emissions by 17 percent
  • Hobby reduced emissions by 32 percent
  • Ellington Airport reduced emissions by 4 percent

"I see firsthand how vital it is to link infrastructure with sustainability,” Houston City Council Member Twila Carter, chair of the council’s Resilience Committee, said in the release. “Reducing carbon emissions at our airports isn’t just about cleaner travel — it’s about smarter planning, safer communities and building a Houston that can thrive for generations to come.”

  • Ivan Korendovych, Baylor University, and Dino Villagrán, The University of Texas at El Paso, “Selective Bio-Inspired Electrochemical Probes for PFAS Analysis and Degradation”
  • Samantha Kristufek, Texas Tech University, and Kayla Green, Texas Christian University, “CIRCUIT: Critical Ion Recovery using Conductive and Ultrafiltration Intelligent Technology”
  • Fang Xu, The University of Texas at San Antonio, and Hong Wang, University of North Texas, “Visualize Molecular Adsorption on Supported Ni-porphyrin Model Catalysts via Substitute Effect”

The Welch Postdoctoral Fellows of the Life Sciences Research Foundation provides three-year fellowships to recent PhD graduates to support clinical research careers in Texas.

The foundation previously announced that it would name fellows from Rice University and Baylor University who would receive $100,000 annually for three years. This year's recipients and their research topics include:

  • Teng Yuan, Rice University, “Unlocking New Chemistry of Nonheme Iron Enzymes for α-Amino Acids and γ-Lactones Synthesis”
  • Katelyn Baumler, Baylor University, "Crystal Growth of Ln2Fe4Sb5 Phases Toward the Study of Novel Quantum Properties”

“As these programs become more established, it is thrilling to see the new research our awardees are exploring,” Adam Kuspa, president of The Welch Foundation, said in a news release. “The Foundation is very pleased by the applications that we continue to receive describing exciting new research projects to advance chemical research.”

This additional funding comes on the heels of the foundation doling out $27 million for chemical research, equipment and postdoctoral fellowships earlier this summer. The foundation made 85 grants to faculty at 16 Texas institutions at the time. Read more here.

Dow aims to power Texas manufacturing complex with next-gen nuclear reactors

clean energy

Dow, a major producer of chemicals and plastics, wants to use next-generation nuclear reactors for clean power and steam at a Texas manufacturing complex instead of natural gas.

Dow's subsidiary, Long Mott Energy, applied Monday to the U.S. Nuclear Regulatory Commission for a construction permit. It said the project with X-energy, an advanced nuclear reactor and fuel company, would nearly eliminate the emissions associated with power and steam generation at its plant in Seadrift, Texas, avoiding roughly 500,000 metric tons of planet-warming greenhouse gas emissions annually.

If built and operated as planned, it would be the first U.S. commercial advanced nuclear power plant for an industrial site, according to the NRC.

For many, nuclear power is emerging as an answer to meet a soaring demand for electricity nationwide, driven by the expansion of data centers and artificial intelligence, manufacturing and electrification, and to stave off the worst effects of a warming planet. However, there are safety and security concerns, the Union of Concerned Scientists cautions. The question of how to store hazardous nuclear waste in the U.S. is unresolved, too.

Dow wants four of X-energy's advanced small modular reactors, the Xe-100. Combined, those could supply up to 320 megawatts of electricity or 800 megawatts of thermal power. X-energy CEO J. Clay Sell said the project would demonstrate how new nuclear technology can meet the massive growth in electricity demand.

The Seadrift manufacturing complex, at about 4,700 acres, has eight production plants owned by Dow and one owned by Braskem. There, Dow makes plastics for a variety of uses including food and beverage packaging and wire and cable insulation, as well as glycols for antifreeze, polyester fabrics and bottles, and oxide derivatives for health and beauty products.

Edward Stones, the business vice president of energy and climate at Dow, said submitting the permit application is an important next step in expanding access to safe, clean, reliable, cost-competitive nuclear energy in the United States. The project is supported by the Department of Energy’s Advanced Reactor Demonstration Program.

The NRC expects the review to take three years or less. If a permit is issued, construction could begin at the end of this decade, so the reactors would be ready early in the 2030s, as the natural gas-fired equipment is retired.

A total of four applicants have asked the NRC for construction permits for advanced nuclear reactors. The NRC issued a permit to Abilene Christian University for a research reactor and to Kairos Power for one reactor and two reactor test versions of that company's design. It's reviewing an application by Bill Gates and his energy company, TerraPower, to build an advanced reactor in Wyoming.

X-energy is also collaborating with Amazon to bring more than 5 gigawatts of new nuclear power projects online across the United States by 2039, beginning in Washington state. Amazon and other tech giants have committed to using renewable energy to meet the surging demand from data centers and artificial intelligence and address climate change.

Texas A&M awarded $1.3M federal grant to develop clean energy tech from electronic waste

seeing green

Texas A&M University in College Station has received a nearly $1.3 million federal grant for development of clean energy technology.

The university will use the $1,280,553 grant from the U.S. Department of Energy to develop a cost-effective, sustainable method for extracting rare earth elements from electronic waste.

Rare earth elements (REEs) are a set of 17 metallic elements.

“REEs are essential components of more than 200 products, especially high-tech consumer products, such as cellular telephones, computer hard drives, electric and hybrid vehicles, and flat-screen monitors and televisions,” according to the Eos news website.

REEs also are found in defense equipment and technology such as electronic displays, guidance systems, lasers, and radar and sonar systems, says Eos.

The grant awarded to Texas A&M was among $17 million in DOE grants given to 14 projects that seek to accelerate innovation in the critical materials sector. The federal Energy Act of 2020 defines a critical material — such as aluminum, cobalt, copper, lithium, magnesium, nickel, and platinum — as a substance that faces a high risk of supply chain disruption and “serves an essential function” in the energy sector.

“DOE is helping reduce the nation’s dependence on foreign supply chains through innovative solutions that will tap domestic sources of the critical materials needed for next-generation technologies,” says U.S. Energy Secretary Jennifer Granholm. “These investments — part of our industrial strategy — will keep America’s growing manufacturing industry competitive while delivering economic benefits to communities nationwide.”

UH lands $11.8M for first-of-its-kind early language development study

speech funding

Researchers at the University of Houston have secured an $11.8 million grant from the National Institutes of Health to conduct a first-of-its-kind study of early language development.

Led by Elena Grigorenko, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Psychology, and research professor Jack Fletcher, the study will follow 3,600 children aged 18 to 24 months to uncover how language skills develop at this critical stage and why some children experience delays that can influence later growth.

The NIH funding will also support the development of the new national Clinical Research Center on Developmental Language Disorders at UH, which aims to bring experts from psychology, education, health and measurement sciences to study how children learn language.

“This will be the first national study to estimate how common late talking is using a large, representative sample of Houston toddlers,” Grigorenko said in a news release. “By following these children as they grow, we hope to better understand the developmental pathways that can lead to conditions such as developmental language disorder and autism.”

UH’s team will partner with the pediatric clinic network at Texas Children’s Hospital, where children will be screened for early language development, allowing researchers to identify those who show signs of delayed speech. Next, researchers will follow the cohort through early childhood to examine how language abilities evolve and how early delays may lead to later challenges.

The Clinical Research Center on Developmental Language Disorders will be the 14th national research center established at UH, and will include researchers from multiple UH departments, as well as partners at Baylor College of Medicine and the Texas Center for Learning Disorders.

“This level of investment from the National Institutes of Health reflects the significance of this work to address a complex challenge affecting children, families and communities,” Claudia Neuhauser, vice president for research at UH, said in a news release. “By bringing together experts from multiple disciplines and partnering with major health systems across the region, the project reflects our commitment to advancing discoveries that impact our community.”

Elon Musk's SpaceX files initial paperwork to sell shares to the public

Incoming IPO

Elon Musk's space exploration company has filed preliminary paperwork to sell shares to the public, according to two sources familiar with the filing, a blockbuster offering that would likely rank as the biggest ever and could make its founder the world's first trillionaire.

A SpaceX IPO promises to be one of the biggest Wall Street events of the year, with several investment banks lining up to help raise tens of billions to fund Musk's ambitions to set up a base on the moon, put datacenters the size of several football fields in orbit and possibly one day send a man to Mars.

The sources spoke on condition of anonymity because they were not authorized to talk publicly about the confidential registration with the Securities and Exchange Commission.

SpaceX did not respond immediately to a request for comment.

Exactly how much SpaceX plans to raise has not been disclosed but the figure is reportedly as much as $75 billion. At that level, the offering would easily eclipse the $29 billion that Saudi Aramco raised in its IPO in 2019.

The offering, coming possibly in June, could value all the shares of SpaceX at $1.5 trillion, nearly double what the company was valued in December when some minority owners sold their stakes, according to research firm Pitchbook, before an acquisition that increased its size.

Musk owns 42% of the SpaceX now, according to Pitchbook, though that figure will change with the IPO when new owners are issued shares. In any case, he is likely to pierce the trillion dollar mark because he is already close. Forbes magazine estimates Musk's net worth at roughly $823 billion.

In addition to making reusable rockets to hurl astronauts and hardware into orbit, SpaceX owns Starlink, the world’s largest satellite communications company. The company also recently brought under its roof two other Musk businesses, social media platform X, formerly Twitter, and artificial intelligence business, xAI, in a controversial transaction because both the seller and the buyer were controlled by him.

SpaceX has become the biggest commercial launch company in its industry, responsible for sending payloads into orbit for customers across the globe, but has also benefited from big taxpayer spending. That has raised conflicts of interest issues given that Musk was the biggest donor to President Donald Trump's campaign and is still a big backer.

In the past five years, SpaceX won $6 billion in contracts from NASA, the Defense Department and other U.S. government agencies, according to USAspending.gov.

Among current SpaceX owners is Donald Trump Jr, the president's oldest son. He owns a shares through 1789 Capital. That venture capital firm made him a partner shortly after his father won the presidency for a second time and has been buying up federal contractors seeking to win taxpayer money ever since.

The White House and Trump himself have repeatedly denied there are any conflicts of interest between his role as president and his family's businesses.
