LH CO2MENT Colorado Project

The LH CO2MENT Colorado carbon capture project evaluated installing a large-scale post-combustion capture system at Holcim’s cement plant near Florence, Colorado using Svante’s VeloxoTherm™ solid sorbent adsorption technology. The feasibility design targeted capturing approximately 1.5 million tonnes of CO₂ per year at ~90% capture efficiency, producing pipeline-grade CO₂ for transport and geological storage. The FEL-2 study developed a full capture, compression, and conditioning design sized at 4,750 tonnes per day of CO₂, with estimated total plant capital costs of approximately $384 million (June 2019 basis) and annual operating costs of about $56 million. The preferred transport concept included building a new 54-mile CO₂ pipeline connection to the existing Sheep Mountain Pipeline, enabling storage either in the Sheep Mountain natural CO₂ reservoir or delivery to Permian Basin EOR storage hubs. Engineering partners included Electricore (project lead), Holcim, Svante (technology licensor), Kiewit (engineering and constructability), Oxy Low Carbon Ventures, and TotalEnergies, with the study funded by the US Department of Energy under a Carbon Capture Demonstration award. The project advanced through FEL-2 but did not proceed to construction following the feasibility phase
