Oman’s carbon capture startup 44.01 raises $37 million

Omani carbon capture startup 44.01 has landed a fresh round of funding as it looks to commercialize its solution in the UAE and Oman — where it has completed pilot projects — to turn CO2 into rock and trap it under the Earth’s surface.

The firm, already backed by Sam Altman’s Apollo Projects, secured $37 million in Series A funding from a group of investors led by the UAE’s Shorooq Partners and Equinor Ventures. Other investors in the round include Amazon’s Climate Pledge Fund and Bill Gates’ Breakthrough Energy Ventures.

44.01 declined to comment to The Circuit on how this round values the four-year-old company, but a spokesman said the next two years will be focused on delivering larger, commercial-scale projects and continuing to refine its technology.

With 50 people on staff across offices in Muscat, Abu Dhabi and London, 44.01 will “as much as double our headcount in the next two years” in engineering and research, the spokesman said. The company also plans to court clients working on carbon removal technologies and so-called “hard-to-abate” industries like steel and cement manufacturing.

Carbon dioxide can turn to rock naturally in a process called mineralization when absorbed by a certain kind of rock. 44.01, named after the molecular mass of CO2, has techniques to massively speed that process up – from decades to less than a year.

Part of the firm’s sales pitch is that rock formations capable of mineralizing and sequestering carbon dioxide are found on every continent, making it a transferrable solution worldwide. 

“Our investors bring a wealth of international expertise and experience that will help us to accelerate our development and ultimately mineralize CO2 at scale worldwide,” Talal Hasan, Founder and CEO of 44.01, said. “We believe mineralization can play a significant role in protecting and repairing our climate.”
