CAPSOL TECHNOLOGIES: MAKING CARBON CAPTURE SAFE AND EFFICIENT 

Challenge:

Most cement CO₂ comes from the calcination of limestone into clinker, which greener energy alone can’t eliminate. Capturing it is key to net-zero cement, but remains costly and energy-intensive. 

Solution:

Capsol’s post-combustion carbon capture and heat recovery system delivers superior efficiency with a proven and safe hot potassium carbonate solvent (HPC). HPC technology is a mature, energy-efficient chemical absorption process used to remove CO₂ from gas streams, that is widely applicable in post-combustion carbon capture.

1. Ram Muthu, Head of Operational Excellence, Holcim:

“By combining Holcim’s expertise in cement manufacturing and on-site carbon capture with Capsol’s safe and efficient technology, we have an additional lever to advance decarbonization and drive profitable growth. Through this strategic investment, we are one step closer to producing near-zero cement at scale to meet growing customer demand.” 

2.  Wendy Lam, CEO, Capsol:

“Holcim is a leading provider of sustainable construction solutions and one of the largest cement producers in the world. They have bold ambitions of producing near-zero cement at scale for customers. Capsol wants to be part of realizing this ambition. Today, we are proud to share how we are deepening our collaboration, following a CapsolGo demonstration project at Holcim’s Dotternhausen plant in Germany in 2025. We look forward to further developing our relationship with Holcim and innovating together for the future.”
