Carbon Capture Costs: FEED & pre-FEED Cost Reports

Membrane Technology & Research Inc., with Sargent & Lundy and CEMEX, is designing a full-scale Polaris membrane CO₂ capture system for the CEMEX Balcones cement plant in New Braunfels, Texas, targeting about 1 million tonnes of CO₂ capture annually. The study will develop the design basis, process design, cost estimates, permitting and safety reviews, constructability assessment, and a techno-economic analysis. Sargent & Lundy will lead the design work, while CEMEX will provide site-specific data for integration.

Membrane Technology and Research Inc., with Technology Centre Mongstad, Dresser-Rand, Trimeric Corporation, and WorleyParsons/Advisian, is scaling up its advanced Polaris™ membranes for post-combustion CO₂ capture and testing them at engineering scale at TCM in Norway. The Polaris membranes, about 20 times more permeable than prior commercial versions, use a patented selective recycle design to boost CO₂ concentration in flue gas and lower capture costs. The project will design, build, and operate a modular membrane system for a six-month field test, including performance verification, steady-state operation, techno-economic updates, and integration studies with advanced compression technology.

Dastur International Inc., with Cleveland-Cliffs Inc., is designing a carbon capture system for the 5 mtpa integrated steel plant in Burns Harbor, Indiana, to capture 50–70% of CO₂ emissions from blast furnace gas. The system will combine a gas flow distribution network, a specialized conditioning process, and ION Clean Energy’s solvent-based capture technology with 90–98% efficiency, with water-gas shift reactors enabling higher capture rates. Dastur will lead overall plant integration and engineering, while ION designs the capture island and Dastur Energy optimizes design and energy performance.
