A carbon innovation initiative in collaboration with Greentown Houston has named its new cohort.

The Carbon to Value Initiative (C2V Initiative) — a collaboration between NYU Tandon School of Engineering's Urban Future Lab (UFL), Greentown Labs, and Fraunhofer USA — has named nine startup participants for the fourth year of its carbontech accelerator program.

"Once again, the C2V Initiative has been able to select some of the most promising carbontech startups through a very competitive process with a 7 percent acceptance rate," Frederic Clerc, director of the C2V Initiative and interim managing director of UFL, says in a news release. "The diversity of this cohort, in its technologies, products, geographies, and stages, makes it an amazing snapshot of the rapidly evolving carbontech innovation landscape."

The cohort was selected from over a hundred applications from nearly 30 countries. In the six-month program, the nine companies gain access to the C2V Initiative's Carbontech Leadership Council, an invitation-only group of corporate, nonprofit, and government leaders who provide commercialization opportunities and identify avenues for technology validation, testing, and demonstration.

The year four cohort, according to the release, includes:

Ardent, from New Castle, Delaware, is a process technology company that is developing membrane-based solutions for point-source carbon capture and other chemical separations.
CarbonBlue, from Haifa, Israel, develops a chemical process that mineralizes and extracts CO2 from water, which then reabsorbs more atmospheric CO2.
MacroCycle, from Somerville, Massachusetts, develops a chemical recycling process to turn polyethylene terephthalate (PET) and polyester-fiber waste into "virgin-grade" plastics.
Maple Materials, from Richmond, California, develops an electrolysis process to convert CO2 into graphite and oxygen.
Oxylus Energy, from New Haven, Connecticut, develops a direct electrochemical process to convert CO2 into fuels and chemical feedstocks, such as methanol.
Phlair, from Munich, Germany, develops a renewable-energy-powered Direct Air Capture (DAC) system using an electrochemical process for acid and base generation.
Secant Fuel, from Montreal, Quebec, Canada, develops a one-step electrocatalytic process that converts flue gas into syngas.
RenewCO 2, from Somerset, New Jersey, is developing an electrochemical process to convert CO2 into fuels and chemicals, such as sustainable aviation fuel (SAF) or propylene glycol.
Seabound, from London, England, builds carbon-capture equipment for new and existing ships.

"The depth and breadth of carbontech innovations represented in this applicant pool speaks volumes to this growing and dynamic industry around the world," adds Kevin Dutt, Interim CEO of Greentown Labs. "We're eager to support these nine impressive companies as they progress through this program and look forward to seeing how they engage with the CLC now and into the future."

The C2V Initiative kicked off at a public event on Sept. 19 at Greentown Houston and via livestream.

New York company Andium is a centralized and optimized operations platform for large energy companies.
Elementium Materials, a local Katy-based company, created its battery technology that originated out of MIT.
Splight is a San Mateo, California-based technology platform that provides real-time operational data based on inverter-based resources assets.
Los Angeles-based Mitico, one of the Rice Alliance Clean Energy Accelerator's class 4 participants, provides services and equipment for carbon capture through its granulated metal carbonate sorption technology.
From Cambridge, Massachusetts, Osmoses is changing the way molecular gas separations are performed within the chemical, petrochemical, and energy industries.
Rice Alliance Clean Energy Accelerator class 4 participant CORROLYTICS, based in Houston, has a corrosion detection and monitoring technology. The company also won over the crowd and secured the People's Choice win too.
Ardent, based in New Castle, Delaware, has developed a membrane technology for point-source carbon capture.
New Haven, Connecticut-based Oxylus Energy produces an alternative fuel from converting CO2 into green methanol.

Last year, investors named its selection of most-promising companies at Rice.

"We have a responsibility as a city to lead energy transition," Cherukuri continues. "A lot of the investments we're making at Rice are going to change the world."

Johnson Space Center and UT partner to expand research, workforce development

onward and upward

NASA’s Johnson Space Center in Houston has forged a partnership with the University of Texas System to expand collaboration on research, workforce development and education that supports space exploration and national security.

“It’s an exciting time for the UT System and NASA to come together in new ways because Texas is at the epicenter of America’s space future. It’s an area where America is dominant, and we are committed as a university system to maintaining and growing that dominance,” Dr. John Zerwas, chancellor of the UT System, said in a news release.

Vanessa Wyche, director of Johnson Space Center, added that the partnership with the UT System “will enable us to meet our nation’s exploration goals and advance the future of space exploration.”

The news release noted that UT Health Houston and the UT Medical Branch in Galveston already collaborate with NASA. The UT Medical Branch’s aerospace medicine residency program and UT Health Houston’s space medicine program train NASA astronauts.

“We’re living through a unique moment where aerospace innovation, national security, economic transformation, and scientific discovery are converging like never before in Texas," Zerwas said. “UT institutions are uniquely positioned to partner with NASA in building a stronger and safer Texas.”

Zerwas became chancellor of the UT System in 2025. He joined the system in 2019 as executive vice chancellor for health affairs. Zerwas represented northwestern Ford Bend County in the Texas House from 2007 to 2019.

In 1996, he co-founded a Houston-area medical practice that became part of US Anesthesia Partners in 2012. He remained active in the practice until joining the UT System. Zerwas was chief medical officer of the Memorial Hermann Hospital System from 2003 to 2008 and was its chief physician integration officer until 2009.

Zerwas, a 1973 graduate of the Houston area’s Bellaire High School, is an alumnus of the University of Houston and Baylor College of Medicine.

Texas booms as No. 3 best state to start a business right now

Innovation Starts Here

High employment growth and advantageous entrepreneurship rates have led Texas into a triumphant No. 3 spot in WalletHub's ranking of "Best and Worst States to Start a Business" for 2026.

Texas bounced back into the No. 3 spot nationally for the first time since 2023. After dropping into 8th place in 2024, the state hustled into No. 4 last year.

Ever year, WalletHub compares all 50 states based on their business environment, costs, and access to financial resources to determine the best places for starting a business. The study analyzes 25 relevant metrics to determine the rankings, such as labor costs, office space affordability, financial accessibility, the number of startups per capita, and more.

When about half of all new businesses don't last more than five years, finding the right environment for a startup is vital for long-term success, the report says.

Here's how Texas ranked across the three main categories in the study:

No. 1 – Business environment
No. 11 – Access to resources
No. 34 – Business costs

The state boasts the 10th highest entrepreneurship rates nationwide, and it has the 11th-highest share of fast-growing firms. WalletHub also noted that more than half (53 percent) of all Texas businesses are located in "strong clusters," which suggests they are more likely to be successful long-term.

"Clusters are interconnected businesses that specialize in the same field, and 'strong clusters' are ones that are in the top 25 percent of all regions for their particular specialization," the report said. "If businesses fit into one of these clusters, they will have an easier time getting the materials they need, and can tap into an existing customer base. To some degree, it might mean more competition, though."

Texas business owners should also keep their eye on Houston, which was recently ranked the 7th best U.S. city for starting a new business, and it was dubbed one of the top-10 tech hubs in North America. Workers in Texas are the "third-most engaged" in the country, the study added, a promising attribute for employers searching for the right place to begin their next business venture.

"Business owners in Texas benefit from favorable conditions, as the state has the third-highest growth in working-age population and the third-highest employment growth in the country, too," the report said.

The top 10 best states for starting a business in 2026 are:

No. 1 – Florida
No. 2 – Utah
No. 3 – Texas
No. 4 – Oklahoma
No. 5 – Idaho
No. 6 – Mississippi
No. 7 – Georgia
No. 8 – Indiana
No. 9 – Nevada
No. 10 – California
