St Marys Cement Carbon Capture

The St. Marys Cement Carbon Capture project is a DOE-funded pilot demonstration testing a membrane–sorbent hybrid CO₂ capture system at the St. Marys Cement Charlevoix plant in Michigan. The project will capture approximately 3 tonnes of CO₂ per day from a cement kiln flue gas slipstream and evaluate performance at capture rates exceeding 95%. The pilot includes design, fabrication, installation, six months of on-site operation, and full techno-economic and environmental assessment to de-risk scale-up of the technology for commercial cement applications. The project runs from December 2024 through November 2028 with total funding of approximately $9.6 million, including $7.0 million from the U.S. Department of Energy and $2.6 million in cost share . Project participants and roles (1) Membrane Technology and Research (MTR) serves as project lead and technology provider, responsible for membrane system design, fabrication, installation, operation, data analysis, and reporting to DOE. (2) St. Marys Cement hosts the pilot at its Charlevoix plant and supports site engineering and on-site operations. (3) Sargent & Lundy manages site engineering design, construction preparation, system installation, and decommissioning activities. (4) TDA Research supplies and integrates the solid sorbent capture system and supports operation and performance analysis. (5) Trimeric Corporation provides techno-economic analysis and environmental health and safety risk assessment support
