Holcim has taken a strategic equity stake in Norwegian carbon capture specialist Capsol Technologies, reinforcing its push to commercialize low-emissions cement production and expand on-site carbon capture deployment across its global operations.
Capsol develops post-combustion capture systems based on hot potassium carbonate (HPC) solvents, a chemical absorption process widely used in industrial gas treatment.
The company’s technology integrates carbon capture with heat recovery, improving overall energy efficiency – a critical factor for high-temperature, energy-intensive cement plants.
Holcim said the investment aligns with its long-term decarbonization roadmap and broader ambition to bring near-zero cement products to market at scale.
The construction materials group views on-site capture as a key pathway for addressing process emissions inherent to cement manufacturing, which cannot be eliminated through fuel switching alone.
Ram Muthu, Holcim’s Head of Operational Excellence, said the partnership combines Holcim’s operational expertise with Capsol’s capture platform to unlock new commercial and environmental value.
From Pilot Projects to Industrial Scale
The investment follows a CapsolGo® demonstration project at Holcim’s Dotternhausen cement plant in Germany in 2025, where the two companies tested the technology under real operating conditions. Capsol CEO Wendy Lam said the partnership represents a natural progression from pilot deployment toward long-term industrial collaboration.
Lam highlighted Holcim’s role as a global leader in sustainable construction materials, noting that scaling carbon capture across cement production could significantly accelerate emissions reductions in one of the world’s most carbon-intensive industries.

Beyond Capsol, the deal also reflects Holcim’s broader venture strategy. Through its MAQER Ventures platform, the company screens more than 500 climate and construction technology startups each year and has completed 19 strategic investments to date.
The initiative is designed to identify scalable decarbonization solutions across the built environment, from alternative materials to digital efficiency tools and carbon capture systems.
As cement producers face tightening climate regulations and rising demand for low-carbon building materials, partnerships like Holcim and Capsol’s are expected to play a growing role in shaping the next generation of industrial decarbonization technologies.
