Houston investors are betting on a New York-based carbon capture startup's technology.

CarbonQuest announced it received series A funding from Houston-based Riverbend Energy Group. The terms of the deal were not disclosed. Founded in 2019, the company created its Distributed Carbon Capture technology that captures CO2 from buildings and onsite power generation systems, then liquifies and transports it to local businesses that need carbon for their production processes.

“We are one of the few carbon capture companies with commercial products on the market today, and this investment will enable us to continue bringing distributed carbon capture to a wider swath of the market,” Shane Johnson, president and CEO of CarbonQuest, says in a news release. “We are also excited to attract new talent and expand our North American operations.”

The company's compact, modular carbon capture solution has already been deployed in several New York City buildings and reports that it is focused on natural gas emissions from distributed onsite power generation in 2024. The fresh funding will help CarbonQuest lower its cost for customers and address new market segments, including biogenic sources of CO2, utility infrastructure, and more, per the release.

Additionally, the company plans to advance development of its Carbon Management Software, a platform that provides real-time data and analytics for users. Riverbend's Joe Passanante and Eric Danziger will join CarbonQuest’s board of directors as a part of the deal.

“We are thrilled to partner with CarbonQuest, a company at the forefront of distributed carbon capture technology,” Passanante, managing director at Riverbend, says in the release. “This investment reflects our commitment to advancing solutions that play a critical role in decarbonization.

"CarbonQuest’s innovative approach not only addresses that need, but also offers scalable, economically viable solutions that can be deployed across a wide range of markets," he continues. "We are excited to collaborate with CarbonQuest’s experienced and talented team and believe this partnership will be a game changer in multiple markets, helping to unlock the full potential of distributed carbon capture and significantly contribute to global climate goals.”

SEG Solar has announced plans to open a new 1.15 million-square-foot solar module facility in Tomball—its third in the Houston area.

The news comes just weeks after the Houston-based solar manufacturer announced its second facility, which will be located in Cypress. It’s expected to open in August.

The latest 4.6-gigawatt facility in Tomball will include an assembly factory and a warehouse. Construction is slated to wrap in March 2027, with commercial panel production planned to begin in May 2027. Once completed, the facility will bring SEG’s annual U.S. module manufacturing capacity to 10.6 gigawatts, according to a news release from the company, one of the largest totals in the country.

The facility will produce heterojunction technology (HJT) modules, which the company says will add to the number of n-type solar panels made in the U.S. HJT modules are known to be more durable and are well suited for hotter climates.

“Designed to support next-generation HJT technology and FEOC-compliant production, the facility ensures reliable, high-efficiency solar solutions,” Raymond Bailey, sales manager at SEG Solar, said in a LinkedIn post. “ Alongside upstream integration in Indonesia and potential U.S. cell manufacturing, we are strengthening supply chain resilience amid evolving trade policies.”

SEG opened its $60 million, 250,000-square-foot facility in Houston in 2024 to house its production workshops, raw material warehouses, administrative offices, finished goods warehouses, and supporting infrastructure. The continued expansion is part of SEG’s long-term goal of becoming one of the largest 100 percent U.S.-owned module manufacturers.
