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 will host a public Year 4 kickoff event on Sept. 19 at Greentown Houston and via livestream.

A View From HETI

Artificial intelligence is now everywhere. It is mentioned in every startup pitch deck, and every corporate roadmap claims to use it. However, many early-stage businesses struggle with the simple question, “What does AI actually mean for my business?”

In a recent podcast episode of EnergyTech Startups, Merab Momen, founder of AI CTO Services and a long time AI practitioner, explains why most founders misunderstand AI, how startups can practically apply it and why Houston is quietly becoming a serious hub for AI-driven innovation.

Filling the AI Leadership Gap

Merab’s career has spanned decades of technology transitions. He worked on neutral networks in the 1990s, constructed computer vision systems long before they were common, and helped install AI solutions inside huge industrial companies. However, he noticed a huge problem when generative AI started to explode into the mainstream-The requirement of a real partner by the founders for AI integration but inability to rely on a full-time CTO and project-based consultants.

“I really needed something which is much more engaging where I can give that partner-level advice to the founders,” he said. By giving firms on-demand access to high-level AI knowledge and expertise, his methodology enables them to analyse tools, steer clear of cost blunders and eventually transition to a permanent technology leader when the time is right.

AI is Older than Most People Think

Despite its recent rise in popularity, AI is nothing new. AI actually began in the 1950s. Merab in his conversation explained how he worked on his first AI project back in the year 1996 that worked perfectly, but the processing power wasn’t just there to make it practical. He continued how he utilized the swarm intelligence models to optimize supply chains, now referred to as MLPOs and data engineering.

From Language Models to Physical World

Much of the public conversation about AI revolves around chatbots and text generation. But Merab sees far greater potential in AI’s interaction with the physical world, especially in industrial settings. He emphasized edge computing and vision language models (VLMs) as significant advances in manufacturing and energy. This physical shift is opening doors for new opportunities for robotics, automated inspections, and industrial safety applications. Merab added that Houston is uniquely positioned for this transition.

Why Houston has an AI Advantage

Silicon Valley may dominate the AI headlines, but Merab believes Houston’s advantage lies beneath the surface. The city doesn’t lag in AI utilization; it just operates in industries where results show differently.

Machine learning isn’t new to Houston’s core industries. Energy companies, manufacturers, logistics providers, and healthcare systems have been using advanced analytics for decades. The difference lies in them innovating in industrial sectors rather than consumer technology.

What’s Next

With the AI CTO Services growing, Merab is working with startups across industries to deploy AI in practical, business-first ways.

He is more interested in assisting founders in finding answers to critical issues than following new trends.

For Houston’s energy and climate tech community, it needs to transform AI enthusiasm into real-world impact.
