About
44.01 mineralizes captured carbon dioxide by injecting it into reactive peridotite rock, permanently converting CO2 into stone. Founded in Oman in 2020 to use that country's large peridotite formations, the company takes CO2 captured from the air or from hard-to-abate industrial processes and locks it away through accelerated mineralization. It works with energy and industrial partners—including projects with ADNOC, Holcim, and Oman's Ministry of Energy and Minerals—to scale carbon removal safely and permanently.
