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

Texas loses speed among top EV states, apps open for Greentown program, and more things to know this week

take note

Editor's note: Dive headfirst into the new week with three quick things to catch up on in Houston's energy transition: applications for a Greentown Labs program has opened, Texas falls flat on a ranking of best EV states, and more.

Texas puts it in park near the bottom of list of best states for EV drivers

You’d think that producing tens of thousands of Teslas might help drive up Texas’ standing among the best states for owning an electric vehicle. To the contrary, Texas ranks among the worst states to be an EV owner.

A new list from EV Charger Reviews puts Texas in the No. 2 position among the worst states for owning an EV. Washington leads the pack of the worst EV states. Topping the list of the best states for EV owners is Maine, followed by Colorado and Vermont. Read more about the methodology.

Big deal: GridBeyond's $55M series C

GridBeyond,which has its U.S. headquarters in Houston, raised its series C to support its growth in the the United States.

The round closed at €52 million, or around $55 million. Founded in 2010, GridBeyond's AI platform allows businesses to unlock the full potential of energy assets and prioritize sustainability, resilience, and affordability of energy.

"This funding, together with the support of our new partners, will enable us to expand our product offering and strengthen our leadership position in this space," Michael Phelan, co-founder and CEO of GridBeyond, says in a news release. “The newly completed financing round sets GridBeyond on the path to increase the reach of our intelligent energy platform and deliver world leading AI and powerful automation capabilities to smart grid and energy markets across the world."

Greentown Labs opens C2V Initiative apps

For the fourth year, the Carbon to Value Initiative, a multi-year collaboration from the Urban Future Lab at NYU Tandon School of Engineering, Greentown Labs, and Fraunhofer USA — has opened applications. The program is looking for "startups at Technology Readiness Level 4-7 that are developing carbontech innovations related to carbon conversion to added-value products; carbon capture; and carbon sequestration and removal," according to Greentown.

The selected cohort will have access to the C2V Initiative’s CLC, an invitation-only group of corporate, nonprofit, and government thought leaders across the energy industry. Startups will also each receive a $10,000 stipend to support their participation in the accelerator. Applications are open through June 21, 2024.

Energy AI company opens first U.S. office in Houston after Halliburton deal

houston expansion

Building on its partnership with Houston-based oilfield services provider Halliburton, energy-sector AI company Shape Digital recently opened an office at The Ion. It’s the company’s first U.S. location.

Shape Digital’s workforce in Houston includes employees specializing in tech support, business development and client services. The company’s local hiring projections and headcount weren’t available. The new office will be located within Industrious at the Ion, according to Rice Alliance.

A key driver of the new Houston office: The company forecasts North America will account for more than 20 percent of its business in 2027.

“North America is a critical market for industrial innovation, and Houston sits at the center of companies driving that progress,” Caio Sene, vice president of client services at Shape Digital, said in a release. “Growing our presence here allows us to work alongside operators as they look for practical ways to turn existing operational data into clear recommendations for what to do next.”

Shape Digital, which also has offices in Singapore and Brazil, develops decision-making platforms for the oil and gas sector.

The Ion District office gives Shape Digital a presence close to Halliburton’s headquarters. In May, the two companies forged a partnership to combine Halliburton’s Digital Field Solverdecision-making system with Shape Digital’s AI portfolio.

Shape Digital layers AI software atop existing operations data rather than replacing legacy systems or adding new software.

The company’s suite of AI agents draws on more than 200 operations-monitoring algorithms, continually learning from company and industry data. The suite comprises four products: Shape Aura, Shape Lighthouse, Shape Lumen and Shape Reef.

Shape Digital says that by working with a customer’s existing operations data, it can deliver ROI in less than two months without any additional investment in equipment or infrastructure.

The company is a 2021 spinoff of Japan-based Modec. Modec builds, owns, and operates floating offshore oil and gas production facilities. Its Modec America subsidiary is based in Houston.

Houston energy startup names former Cheniere execs to C-suite

new leaders

Houston-based energy infrastructure startup Joulent has brought aboard a new chief financial officer and new chief operating officer—both former executives at Houston-based Cheniere Energy.

The C-suite moves come three months after Joulent raised $1.75 billion from National Grid Ventures.

Michael Wortley joins Joulent as co-president and CFO. Wortley most recently was executive vice president and CFO at Cheniere, an LNG producer and exporter.

In conjunction with Wortley’s hiring, Brian Boland, who was Joulent’s interim CFO, has been named executive vice president, chief investment officer, and head of strategy.

Corey Grindal comes to Joulent as co-president and COO. Grindal most recently was executive vice president and COO at Cheniere.

“As Joulent evolves to meet the growing demand for power infrastructure, our expanded leadership team will help ensure we continue delivering the execution certainty our customers, partners, and investors expect,” Chris James, Joulent’s founder and CEO, said in a press release.

“Corey and Michael are accomplished operators with exceptional records of building and leading world-class energy infrastructure businesses, where they have embedded a culture defined by operational excellence and disciplined execution,” James added.

Joulet builds dedicated power-generating facilities that feed directly into data centers and other power-dependent facilities. This eliminates the need for companies to draw power from grids.

“With an initial multi-gigawatt development portfolio and strategic partnerships across the energy, infrastructure, and data center ecosystem, Joulent is helping remove power constraints to enable the next chapter of American innovation and U.S. reindustrialization,” the company says.

The $1.75 billion minority investment from National Grid Ventures complements Joulent’s existing partnerships.

Joulent, founded in 2023, emerged from stealth mode this summer. The company was founded by investment firm Engine No. 1.

Joulent’s first project, the Project Kilby natural gas facility in West Texas, will be co-located with a Microsoft data center. It’ll deliver about 2.67 gigawatts of power under a 20-year deal between Microsoft and Energy Forge One, a 50/50 joint venture between Chevron and Joulent.
