Holcim stock gains a new strategic angle through an investment in carbon-storage developer 44.01. A UAE pilot is already storing captured carbon underground.

Carbon storage strategy takes shape

Holcim invested in 44.01 to support the developer's international expansion and technology scale-up.

Holcim announced on November 4 that it had invested in 44.01, a developer of carbon-mineralization technology. The investment supports 44.01's international expansion and scale-up while extending an established commercial relationship between the companies, according to the Holcim media release.

44.01 injects captured carbon dioxide into naturally reactive ultramafic rock formations. The gas reacts with the rock and is mineralized into stable carbonate rock, creating a storage route that differs from keeping carbon dioxide in a separate compressed underground reservoir.

Fujairah pilot moves into operation

Since July, Holcim and 44.01 have been running a pilot under live industrial conditions at Holcim's Fujairah cement plant in the United Arab Emirates. Holcim said captured carbon dioxide is already being stored underground near the plant and converted into solid rock.

The pilot gives the partners an operating setting in which to assess capture, transport, injection and mineralization close to a cement facility. Holcim presents the approach as relevant to inland operations where access to offshore storage networks may be limited, although wider deployment will depend on local geology and the technology's ability to scale.

Technology adds a strategic option

Ram Muthu, Holcim's head of operational excellence, said the investment builds on the existing UAE project. He described the technology as a way to store carbon close to production where geological conditions are suitable and linked the initiative to Holcim's NextGen Growth 2030 strategy.

The company described the transaction as part of its open innovation ecosystem. Holcim said its corporate venture capital and open innovation unit, Holcim MAQER Ventures, has made 22 investments to date. Other investors in 44.01 include JERA, Breakthrough Energy Ventures, Equinor Ventures, Air Liquide Venture Capital and Siemens Financial Services.

The amount invested and Holcim's ownership interest were not disclosed. As a result, the immediate earnings effect cannot be quantified from the announcement. For investors, the transaction primarily adds an option on future carbon-management infrastructure rather than a disclosed near-term revenue stream. Its commercial significance will depend on further projects, operating results and the economics of deploying the process at additional plants.
