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.
  • RenewCO2, 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.

Investors from around the world again identified the most-promising energy tech startups at the Rice Alliance for Technology and Entrepreneurship's annual event.

"The recognition that Houston is the epicenter of energy transition is growing. It's something we are championing as much as possible so that the world can know exactly what we're doing," Paul Cherukuri, chief innovation officer at Rice University says at the 21st annual Energy Tech Venture Forum.

The event took place during the inaugural Houston Energy and Climate Startup Week, and nearly 100 startups from 23 states and seven countries pitched investors Wednesday, September 11, and Thursday, September 12. At the conclusion of the event, the investors decided on 10 companies deemed "most promising" from the presentations.

This year's selected companies are:

  • Revterra, a Houston-based company innovating within kinetic battery technology to enable faster and cleaner electric vehicle charging.

Houston Innovation Awards honor Don Kendall Jr. with posthumous​ Trailblazer Legacy Award

lasting legacy

Every year, the Houston Innovation Awards honor one Houstonian with the Trailblazer Award, whose impact is felt throughout the city's innovation and business ecosystem.

This year, the Trailblazer Legacy Award will be given posthumously to Don Kendall Jr., who died in September while on a trip to the Republic of the Congo with the Jane Goodall Institute, one of the many organizations he was deeply involved with.

Kendall's obituary puts it simply: "Don’s truest passions were conservation and his family." Many saw those passions play out in his career, particularly in the role he played in shaping Houston's clean energy sector.

Kendall served as general partner of New Climate Ventures, a Houston-based early-stage venture capital firm that invests in next-gen energy, materials and fuel technologies and startups. The firm's portfolio includes Houston-based clean energy companies like Solidec, Syzygy Plasmonics and Rheom Materials.

Kendall was also founding managing director and CEO of Kenmont Capital LP. He ran a $500 million distressed debt and credit-based hedge fund focused on the energy, power and transportation sectors and one of the top-performing private equity funds under the Kenmont umbrella.

He served on the board of Talos Energy, American Midstream Partners, Syzygy Plasmonics, Tangent Energy, Stream Energy and others. Notably, he served as Chair of the Special Committee of the SolarCity board during its acquisition by Tesla in 2016. According to his obituary, Kendall negotiated with "Elon Musk in the middle of the night on a rickety pier in Indonesia after eluding a poisonous snake."

Outside of the clean energy space, Kendall also served on the boards of the Jane Goodall Institute, Earthwatch International and Ecological Defense Group. He also served as vice chair of the Houston Zoo Inc. and chair of its Conservation Committee.

Kendall was selected by our esteemed panel of judges to receive the 2026 Trailblazer Legacy Award. The panel includes carbon removal entrepreneur and CEO of Houston-based Mars Materials Aaron Fitzgerald.

Fitzgerald shares the profound impact Kendall had on his career and those of many others.

"Honoring Don with the Trailblazer Legacy Award is a fitting tribute to a leader whose impact spanned civic work with the Houston Zoo, wildlife conservation, and the growth of our startup ecosystem," Fitzgerald says. "He paired a keen eye for potential with the relentless drive to unlock it. For Mars Materials, his early backing carried us through a critical valley when we needed belief the most, and his presence as a personal mentor is profoundly missed."

Don was an avid traveler, cyclist and collector. He is survived by his wife of 50 years, Diane S. Kendall. A celebration of life will be held early in 2027.

2 Houston suburbs rank among 5 best cities to retire, says U.S. News

Slowing Down

Houston and nine of its suburbs are earning new acclaim on U.S. News and World Report's just-released list of the best U.S. cities for retirees in 2027. Two northern suburbs, The Woodlands and Spring, are resting easy among the top five nationwide.

The 2027 Best Places to Retire list evaluated over 850 U.S. cities based on six livability metrics that best serve American retirees: quality of life, affordability, health care, retiree taxes, job market, and population and migration. The top 250 finalist cities were then ranked nationally and by city size.

Midland, Michigan topped the list for the second consecutive year and is followed by Homosassa Springs, Florida (No. 2) and Weirton, West Virginia (No. 3).

The Woodlands and Spring respectively maintained their standings as the No. 4 and No. 5 best cities for retirees for the second year in a row. The Woodlands topped the separate list of the best midsized U.S. cities to retire, while Spring landed 5th among the smallest U.S. cities.

Houston proper was declared the No. 2 best big city for retirees, and it ranked 89th overall. Elsewhere in the metro, Pearland (No. 13) and Conroe (No. 14) ranked just outside the overall top 10 but ranked 4th and 5th among the best midsized cities for retirees.

U.S. News said affordability is the "most considered factor" when it comes to picking the best place to live a low-stress retirement life, and that's what Houston and its neighbors deliver. Affordable cities also give retirees "a sense of security and comfort as they live out their golden years," according to Megan Wood, U.S. News assistant managing editor of home services and real estate.

"It’s no secret that affordability is top of mind for Americans this year, which is why U.S. News updated its weighting criteria to better align with what retirees prioritize," Wood said. "The 2027 rankings reflect key metrics used to highlight the places that
best suit retiree needs."

Sugar Land was declared the 10th best place to live in the U.S. in a separate U.S. News report earlier this year, but it doesn't quite meet the expectations for retirees. This particular suburb ranked as the 45th best overall city to retire, but it fared better in the city size ranking and landed 13th among the biggest U.S. cities.

Pasadena also surprised as the 85th best place to retire nationwide in this report, despite being hailed as the No. 3 best city to retire in Texas by RetirementLiving.com.

Three more Houston neighbors ranked among the top 100 overall best places to retire for 2027: League City (No. 25), Missouri City (No. 49), and Baytown (No. 88).

These are the top 10 best U.S. cities to retire for 2027:

  • No. 1 – Midland, Michigan
  • No. 2 – Homosassa Springs, Florida
  • No. 3 – Weirton, West Virginia
  • No. 4 – The Woodlands
  • No. 5 – Spring, Texas
  • No. 6 – Rio Rancho, New Mexico
  • No. 7 – Altoona, Pennsylvania
  • No. 8 – Paducah, Kentucky
  • No. 9 – Lynchburg, Virginia
  • No. 10 – Palm Coast, Florida
