Manufacturing

Ardent is a process technology company that is developing membrane-based solutions for point-source carbon capture and other chemical separations. The startup is participating in Year 4 of the Carbon to Value Initiative (C2V Initiative). (Greentown Houston)

CarbonBlue, a C2V Initiative Year 4 cohort member, develops a chemical process that mineralizes and extracts CO₂ from water, which then reabsorbs more atmospheric CO₂. (Greentown Houston)

MacroCycle develops a chemical recycling process to turn polyethylene terephthalate (PET) and polyester-fiber waste into “virgin-grade” plastics. The startup is part of Year 4 of the C2V Initiative. (Greentown Boston)

Maple Materials develops an electrolysis process to convert CO₂ into graphite and oxygen. The startup is a Greentown Go alum that’s returning for Year 4 of the C2V Initiative. (Greentown Houston)

Phlair, a participant in Year 4 of the C2V Initiative, develops a renewable-energy-powered direct air capture (DAC) system using an electrochemical process for acid and base generation. (Greentown Boston)

RenewCO₂ is developing an electrochemical process to convert CO₂ into fuels and chemicals, such as sustainable aviation fuel or propylene glycol. It previously participated in a Greentown Go program and is part of this year’s C2V Initiative cohort. (Greentown Boston)

Secant Fuel, a C2V Initiative Year 4 cohort member, develops a one-step electrocatalytic process that converts flue gas into syngas. (Greentown Houston)

XTPL is developing breakthrough additive manufacturing technology for ultra-precise printing of nanomaterials. (Greentown Boston)

Resiliency + Adaptation

change:WATER Labs is developing a low-cost, compact, waterless toilet for non-sewered households and communities. (Greentown Boston)

Deep Anchor Solutions accelerates renewable energy project adoption, especially in floating offshore wind and other offshore sectors, with its innovative deeply embedded ring anchor. (Greentown Houston)

Giner Labs develops innovative solutions in electrochemical sensors, electrolyzers, fuel cells, advanced materials, and medical devices. (Greentown Boston)

Provocative builds data-centers with cooling systems replaced by carbon-capture. (Greentown Boston)

Thiozen’s proprietary chemical waste-to-hydrogen cycle removes hydrogen sulfide from gas streams and generates zero-emission hydrogen. (Greentown Houston)

TS-Nano is an energy technology company focused on reducing methane emissions from abandoned wellbores using its patented sealants, monitoring technologies, and blockchain carbon offsets—enabling its partners to achieve their ESG and decarbonization goals. (Greentown Houston)

Transportation

eSki Watercraft specializes in electric personal watercraft that excel in meeting the demands of rental businesses while setting a new standard in environmental responsibility. (Greentown Boston)

Oxylus Energy, a C2V Initiative Year 4 cohort member, develops a direct electrochemical process to convert CO₂ into fuels and chemical feedstocks, such as methanol. (Greentown Boston)

Revvit is building low-cost and simple EV charging at commercial, multifamily, fleet parking, and public properties. Its product has demonstrated 85 percent cost savings on install and allows properties to achieve scale, future proofing, and parking flexibility with charging that exceeds other products on the market. (Greentown Boston)

Seabound builds carbon-capture equipment for new and existing ships. The startup is participating in Year 4 of the C2V Initiative. (Greentown Houston)
