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.

Linde Inc., with Linde Engineering Americas and BASF, is conducting an initial engineering design for a 3,500 tonnes/day CO₂ capture plant using Linde-BASF’s advanced aqueous amine technology at a Linde-owned steam methane reforming facility. The project will define integration options, establish project requirements, optimize process design, and develop engineering, cost, and schedule packages. BASF will provide the technology design, LEA will deliver detailed engineering and constructability assessments, and Linde will lead techno-economic, environmental, and safety analyses in coordination with the SMR plant operators.

The CEMEX Balcones Carbon Capture project is a DOE-supported Front-End Engineering Design (FEED) study evaluating commercial-scale deployment of RTI International’s non-aqueous solvent (NAS) technology at the Balcones cement plant in New Braunfels, Texas. The study assessed capture of approximately 2.4 million tonnes of CO₂ per year at roughly 95% capture efficiency from cement kiln flue gas and an associated natural gas–fired boiler, developing an AACE Class 3 cost estimate and detailed engineering design to support future investment decisions. Led by RTI International with KBR as EPC engineering contractor and SLB Capturi as owner’s engineer and technology licensor, the project evaluated integration challenges such as limited cooling water availability, resulting in a hybrid air- and water-cooling configuration. The FEED estimated total project capital costs of about $849 million and annual operating costs of approximately $109 million, providing a techno-economic basis for large-scale cement decarbonization and future project execution planning.
