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.

Houston organizations team up to accelerate startups with low-carbon solutions

greentown hou

Attention, innovators: A new initiative in Houston is searching for startups whose offerings can help reduce global carbon emissions.

The Low-Carbon Hydrogen Accelerator is a partnership involving Greentown Labs, the Electric Power Research Institute, Shell Oil, the City of Houston, and New York University's Urban Future Lab. The accelerator is seeking applications from startups that are advancing low-carbon hydrogen production, enhancing hydrogen storage and distribution, or providing business models for management of hydrogen supply chains. Applications are due February 9, 2022.

"If we can improve the devices and processes that will be used to make, transport, and store clean hydrogen in the future, it can become a cost-competitive fuel. At the same time, these advances can improve the capacity factor of renewable generation, producing multiple economic and climate benefits," Pat Sapinsley, managing director of cleantech initiatives at the Urban Future Lab, says in a news release.

The six-month accelerator will enable startups to collaborate with the Electric Power Research Institute, utilities, and Shell on tech development, feasibility studies, pilot projects, and other low-carbon efforts.

The institute and Shell will provide startups two routes within the accelerate: a path for validation of their technology and a path for demonstration of their technology.

"Accelerating low-carbon hydrogen technologies is essential to achieving global net-zero targets by 2050," says Neva Espinoza, the institute's vice president of energy supply and low-carbon resources.

Shell foresees hydrogen playing a bigger role in hard-to-decarbonize sectors such as heavy-duty trucking, marine, aviation, chemicals, steel, and cement. Julie Ferland, vice president of innovation excellence at Houston-based Shell Oil, says programs such as the new accelerator will be critical to fostering low-carbon energy.

Earlier this year, after visiting Greentown Labs' Houston location, U.S. Energy Secretary Jennifer Granholm and the U.S. Department of Energy launched the Hydrogen Energy Earthshot to reduce the cost of clean hydrogen by 80 percent to $1 per kilogram by 2030.

"As the Energy Capital of the World, I believe it is our responsibility to continue Houston's legacy of energy innovation and develop the technologies and practices needed to decarbonize the global energy sector," Houston Mayor Sylvester Turner says. "Houston has the skilled workforce and infrastructure to develop clean hydrogen at scale, and Greentown Labs' Low-Carbon Hydrogen Accelerator is a great example of the kind of partnerships we need to make it happen."

Greentown Labs is the largest climatech startup incubator in North America. The Somerville, Massachusetts-based incubator recently opened its Houston location.

Houston startup selected for international carbontech accelerator

the future of climatech

A new international accelerator focused on the commercialization of carbontech has announced its new cohort — and one Houston-based company has made the cut.

Cemvita Factory has been accepted into the Carbon to Value Initiative, a recently launched accelerator supported by The Urban Future Lab at the NYU Tandon School of Engineering, Greentown Labs, and Fraunhofer USA. The program is focused on supporting companies with technologies that capture, convert, and store carbon dioxide (CO₂) into valuable end products or services, according to a news release.

"In addition to being absolutely necessary to stave off dangerous climate impacts, carbontech innovations represent a potential $3 trillion market opportunity," says Pat Sapinsley, managing director at the Urban Future Lab, in the news release. "We are excited to welcome 10 startups, each proposing different business models and technology innovations to realize that opportunity."

Cemvita Factory, which was founded by siblings Tara and Moji Karimi in 2017, has created a way to biomimic photosynthesis to take CO2 and turn it into something usable for its energy clients, like feedstocks. Cemvita has 30 different molecules its technology can produce and works with the likes of BHP, Oxy, and more.

"We are excited to represent Houston in the first cohort for the Carbon to Value Initiative," Moji Karimi tells InnovationMap. "We want to send a message that Houston is not just the Oil and Gas capital of the world, but also the center of gravity for a sustainable Energy Transition."The C2V Initiative selected 10 startups out of over 130 applications from 26 countries. The cohort has technologies ranging from carbon utilization product and process innovations to carbon capture and carbon sequestration solutions.

Cemvita isn't alone in repping the Lone Star State. San Antonio-based CarbonFree, which has commercial technologies that capture and convert industrial CO2 emissions into minerals for sale or storage, also made the cohort.

The other eight non-Texas companies are:

  • Air Company, based in New York City, transforms CO2 into high-purity alcohols that can be used in spirits, sanitizers, and a variety of consumer industries.
  • Reykjavík, Iceland-based Carbfix provides a natural and permanent carbon storage solution by turning CO2 into stone underground.
  • CarbonQuest, based in New York City, provides decarbonization technologies and solutions for buildings with a focus on modular carbon capture.
  • Toronto, Canada-based CERT converts CO2 to chemicals such as ethylene via electrolysis.
  • Made of Air, based in Berlin, Germany creates drop-in ready, durable thermoplastics using carbon captured by biomass.
  • Oakland, California-based Mars Materials develops a new pathway for carbon fiber production using CO2 as a raw material.
  • San Francisco-based Patch is a platform for negative emissions.
  • Planetary Hydrogen, based in Dartmouth, Canada, combines hydrogen production with CO2 sequestration via ocean air capture.

The program kicks off at a virtual event on May 6 from 3-5 p.m. The six-month program will provide its cohort with a customized curriculum, hands-on mentorship, and knowledge-sharing sessions with C2V Initiative's Carbontech Leadership Council — an invitation-only group of international corporate, academic, and government thought leaders.

The cohort will also receive complimentary membership and access to the Greentown Labs community, which includes is recently opened facility in Houston.

"We know that to effectively address the climate crisis and mitigate the effects of climate change, we need to rapidly scale and deploy carbontech solutions to accelerate the energy transition," says Emily Reichert, CEO of Greentown Labs. "We're proud to support these startups from all over the world and look forward to the collaborations that will spark among the startups and our CLC members."

Houston startup debuts bio-based 'leather' fashion collection in Milan

sustainable fashion

Earlier this month, Houston-based Rheom Materials and India’s conscious design studio Econock unveiled a collaborative capsule collection that signaled more than just a product launch.

Hosted at Lineapelle—long considered the global epicenter of the world's premier leather supply chain—in the vaulted exhibition halls of Rho-Fiera Milano, the collection centered around Rheom’s 91 percent bio-based leather alternative, Shorai.

It was a bold move, one that shifted sustainability from a concept discussed in panel sessions to garments that buyers could touch and wear.

The collection featured a bomber-style jacket, an asymmetrical skirt and a suite of accessories—all fabricated from Shorai.

The standout piece, a sculptural jacket featuring a funnel neck and dual-zip closure, was designed for movement, challenging assumptions about performance limitations in bio-based materials. The design of the asymmetrical skirt was drawn from Indian armored warrior traditions, according to Rheom, with biodegradable corozo fasteners.

Built as a modular wardrobe rather than isolated pieces, the collection reflects a shared belief between Rheom and Econock in designing objects that adapt to daily life, according to the companies.

The collection was born out of a new partnership between Rheom and Econock, focused on bringing biobased materials to the market. According to Rheom, the partnership solves a problem that has stalled the adoption of many next-gen textiles: supply chain friction.

While Rheom focuses on engineering scalable bio-based materials, New Delhi-based Econock brings the complementary design and manufacturing ecosystem that integrates artisans, circular materials and production expertise to translate the innovative material into finished goods.

"This partnership removes one of the biggest barriers brands face when adopting next-generation materials,” Megan Beck, Rheom’s director of product, shared in a news release. “By reducing friction across the supply chain, Rheom can connect brands directly with manufacturers who already know how to work with Shorai, making the transition to more sustainable materials far more accessible.”

Sanyam Kapur, advisor of growth and impact at Econock, added: “Our partnership with Rheom Materials represents the benchmark of responsible design where next-gen materials meet craft, creativity, and real-world scalability.”

Rheom, formerly known as Bucha Bio, has developed Shorai, a sustainable leather alternative that can be used for apparel, accessories, car interiors and more; and Benree, an alternative to plastic without the carbon footprint. In 2025, Rheom was a finalist for Startup of the Year in the Houston Innovation Awards.

Shorai is already used by fashion lines like Wuxly and LuckyNelly, according to Rheom. The company scaled production of the sugar-based material last year and says it is now produced in rolls that brands can take to market with the right manufacturer.

Houston clean energy co. secures $100M to deploy tech on global scale

Going Global

Houston-based Utility Global has raised $100 million in an ongoing Series D round to globally deploy its decarbonization technology at an industrial scale.

The round was led by Ara Partners and APG Asset, according to a news release. Utility plans to use the funding to expand manufacturing, grow its teams and support its commercial developments and partnerships.

“This financing marks a critical step in Utility’s transition from a proven technology to full-scale global commercial execution,” Parker Meeks, CEO and president of Utility Global, said in the release. “Industrial customers are no longer looking for pilots or promises; they need deployable solutions that work within existing assets and deliver true economic industrial decarbonization today that is operationally reliable and highly scalable. Utility’s technology produces both economic clean hydrogen and capture-ready CO2 streams, and this capital enables us to scale and deploy that impact globally with speed, discipline, and rigor.”

Utility Global's H2Gen technology produces low-cost, clean hydrogen from water and industrial off-gases without requiring electricity. It's designed to integrate into existing industrial infrastructure in hard-to-abate assets in the steel, refining, petrochemical, chemical, low-carbon fuels, and upstream oil and gas sectors.

“Utility is tackling one of the most difficult challenges in the energy transition: decarbonizing hard‑to‑abate industrial sectors,” Cory Steffek, partner at Ara Partners and Utility Global board chair, said in the release. “What sets Utility apart is its ability to compete head‑to‑head with conventional fossil‑based solutions on cost and reliability, even as it materially reduces emissions. With this new funding, Utility is well-positioned for its next chapter of commercial growth while maintaining the technical excellence and capital discipline that have defined its development to date.”

Utility Global reached several major milestones in 2025. After closing a $53 million Series C, the company agreed to develop at least one decarbonization facility at an ArcelorMittal steel plant in Brazil. It also signed a strategic partnership with California-based Kyocera International Inc. to scale global manufacturing of its H2Gen electrochemical cells.

The company also partnered with Maas Energy Works, another California company, to develop a commercial project integrating Maas’ dairy biogas systems with H2Gen to produce economical, clean hydrogen.

"These projects were never intended to stand alone. They anchor a deep and growing pipeline of commercial projects now in development globally across steel, refining, chemicals, biogas and other hard-to-abate sectors worldwide, Meeks shared in a 2025 year-in-review note. He added that 2026 would be a year of "focused acceleration to scale."

Houston Methodist awarded $4M grant to recruit head of Neal Cancer Center

new hire

Armed with a $4 million state grant, the Houston Methodist Academic Institute has recruited a renowned expert in ovarian and endometrial cancer research to lead the Dr. Mary and Ron Neal Cancer Center.

The grant, provided by the Cancer Prevention and Research Institute of Texas, enabled the institute to lure Dr. Daniela Matei away from Northwestern University’s Feinberg School of Medicine in Chicago. There, she is the Diana Princess of Wales Professor in Cancer Research and chief of the Division of Reproductive Science in Medicine.

Matei will succeed Dr. Jenny Chang, who was hired last year to run the Houston Methodist Academic Institute.

At the Neal Cancer Center, located in the Texas Medical Center complex, oncologists work on innovations in cancer research, treatment, and technology. The center opened in 2021 after the Neals donated $25 million to expand Houston Methodist’s cancer research capabilities. It handles about 7,000 new cases each year involving more than two dozen types of cancer.

U.S. News & World Report puts Houston Methodist Hospital at No. 19 among the country’s best hospitals for cancer care, two spots below Chicago’s Northwestern Memorial Hospital. The University of Texas MD Anderson Cancer Center in Houston sits at No. 1 on the list.

Matei’s research related to ovarian and endometrial cancer holds the potential to benefit tens of thousands of American women. The American Cancer Society estimates:

  • 21,010 women in the U.S. will be diagnosed with ovarian cancer, and 12,450 women will die from it.
  • 68,270 women in the U.S. will be diagnosed with endometrial cancer, and 14,450 women will die from it.

Matei is leaving Northwestern in the wake of widespread cuts in federal funding for medical research. The National Institutes of Health (NIH) has canceled or frozen tens of millions of dollars in grants for Northwestern, the Wall Street Journal reports, and the university has been plugging the gaps with its own money.

“The university is totally keeping us on life support,” Matei told the newspaper last year. “The big question is for how long they can do this.”

According to the Wall Street Journal, Matei’s $5 million NIH grant supporting 69 cancer trials has been caught up in the federal funding chaos, so Northwestern stepped in to cover trial expenses such as nurses’ salaries and diagnostic procedures.

Trial participants include some patients with rare, incurable tumors who are undergoing experimental treatments aligned with the genetics of their condition, the newspaper says.

“It’s certainly a life-and-death situation for cancer patients on these trials,” Matei said in 2025.

Matei is among the beneficiaries of more than $15 million in grants approved February 18 by CPRIT’s board. The grants went toward recruiting five cancer researchers to institutions in Texas.

One of those grants, totaling $1.5 million, went to the University of Houston to recruit Akash Gupta, a research scientist at MIT’s Koch Institute for Integrative Cancer Research. The remaining grants went to recruit scientists to The University of Texas at Dallas and The University of Texas Southwestern Medical Center.
