A plan to turn carbon dioxide into limestone — and sell it at a profit — is getting some high-profile backing as BP Plc signs a deal with a San Antonio chemical company that aims to transform greenhouse gas emissions from a liability to a commodity.
Under the arrangement announced Thursday, BP and CarbonFree Chemicals Holdings LLC will collaborate to develop projects that use CarbonFree’s patented technology to convert carbon dioxide into precipitated calcium carbonate used as a filler in plastics and paper. Together, they will work to pitch industrial facilities, including BP’s industrial customers, on deploying the system.
