Carbon Capture Costs: FEED & pre-FEED Cost Reports

Bechtel National Inc., with the Electric Power Research Institute, is conducting a FEED study to retrofit Panda Power Funds’ 758 MWe natural gas combined cycle plant in Sherman, Texas, with a post-combustion CO₂ capture system. Using an open-access design and a conventional amine absorber-stripper system with a non-proprietary solvent such as MEA, the project targets CO₂ capture for enhanced oil recovery.

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.

The University of Illinois at Urbana-Champaign is leading a FEED study for a commercial-scale CO₂ capture system at Holcim’s Ste. Genevieve cement plant in Missouri, targeting 95% capture efficiency. Using Air Liquide’s Cryocap™ technology, which combines PSA pre-concentration with cryogenic purification, the system will produce high-purity CO₂ for storage near the Prairie State Generating Company in Illinois. UIUC will manage the project and perform economic and impact analyses, while Air Liquide, Kiewit, Visage Energy, and Holcim will contribute to design, safety, environmental, and site integration efforts.
