Holcim invests in 44.01 to advance carbon mineralization technology

Holcim has announced an investment in 44.01, a developer specializing in carbon mineralization technology. The technology involves injecting captured CO2 into naturally reactive ultramafic rock formations, where it mineralizes into stable carbonate rock.

The investment aims to support 44.01 in its international expansion and scaling efforts. This move builds upon an existing commercial relationship between the two companies, which includes a pilot project currently operating at Holcim’s Fujairah cement plant in the United Arab Emirates. In this pilot, CO2 is being stored underground and mineralized into solid rock under live industrial conditions.

According to Ram Muthu, Holcim’s Head of Operational Excellence, the technology allows for carbon storage close to production sites when geological conditions permit. This capability is intended to assist in managing captured carbon at inland sites where offshore storage access may be restricted, supporting Holcim’s NextGen Growth 2030 decarbonization strategy.
