CarbonQuest is a cleantech company built around decarbonizing the built environment, with a leadership team whose experience includes energy software, smart-grid technology, and carbon capture. It began piloting its modular systems in 2021 at a Manhattan residential building, where the installation demonstrated that emissions reduction could fit into space equivalent to three parking spaces. Today, CarbonQuest works with commercial and industrial facilities to capture CO₂ at the source and turn it into a usable or removable material.

AircaptureAircapture designs and builds modular Direct Air Capture systems that produce beverage-grade carbon dioxide on customers’ sites, supplying it on demand from the atmosphere rather than through conventional long-distance distribution. Founded by technologist and DAC pioneer Matt Atwood, the company develops its systems in a 12,000-square-foot West Berkeley office and shop, where it focuses on rapid prototyping and in-house production. Its “CO2 as a Service” model is intended to give manufacturers a more local, reliable supply while reducing transportation-related emissions.
OptimaBiomeOptimaBiome is a decarbonization company developing technology for transportation emissions. Its mobile carbon-capture approach uses a reusable solid matrix to capture CO2 from vehicle exhaust and move it toward storage, offering a bridge as transportation shifts toward net-zero operation.POTOMAC, MD
Turnover LabsFounded in 2022 by chemical engineer Marissa Beatty, New York City-based Turnover Labs builds durable electrolysis systems that convert industrial waste CO2 into chemical building blocks. Its technology is designed to install within existing chemical-plant operations, giving manufacturers a way to reuse impure emissions rather than rely solely on petroleum feedstocks. The early-stage company is developing its platform from laboratory research pioneered at Columbia University toward industrial-scale deployment.
Metasorbex™ CorporationMetasorbex Corporation develops programmable sorbent materials and catalysts that capture industrial carbon dioxide, convert it into useful products, and separate rare earth elements from difficult secondary resources. Founded on a 2020 insight that scalable climate and materials solutions would come from controlling molecular interactions, the company applies one materials platform to both carbon utilization and modular rare-earth recovery. Founder and CEO Edward Chan brings experience commercializing advanced materials at Fortune 500 companies and startups.LOVELAND, OH
