New technology paves the way for virtually CO2-free cement
Holcim has invested in the listed Norwegian company Capsol Technologies. The aim is to scale up its advanced CO2 capture technology and thus further advance Holcim's decarbonisation efforts.
Holcim has agreed to acquire a strategic stake in Capsol Technologies, a specialist in post-combustion carbon capture solutions based in Oslo. This was announced in a statement by the building materials supplier. The focus is on HPC (hot potassium carbonate) technology, an energy-efficient chemical absorption process for capturing CO2 from gas streams, combined with an integrated heat recovery system. Holcim intends to use this technology to promote the large-scale production of virtually CO2-free cement and meet growing customer demand for climate-friendly building materials.
“By combining Holcim’s expertise in cement production and on-site CO2 capture with Capsol’s safe and efficient technology, we have an additional lever to drive decarbonisation and achieve profitable growth,” said Ram Muthu, Head of Operational Excellence at Holcim. “This strategic investment brings us one step closer to large-scale production of virtually CO2-free cement.”
The investment was preceded by a CapsolGo demonstration project at Holcim’s Dotternhausen plant in Germany in 2025, where Capsol successfully tested its technology in an industrial environment. The investment expands Holcim’s portfolio of decarbonisation technologies within its open innovation ecosystem. Through Holcim MAQER Ventures, the Group’s corporate venture capital unit, Holcim has made 19 investments to date and reviews more than 500 start-ups in the field of sustainable construction solutions each year.
