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.

Electric Power Research Institute (EPRI), with Fluor Corporation and California Resources Corporation (CRC), conducted a FEED study to assess the feasibility of retrofitting Fluor’s solvent for post-combustion CO₂ capture at the 550 MW Elk Hills NGCC power plant. The system aims to capture approximately 4,000 tonnes of CO₂ per day (75% of total emissions, or 90% of an 83% slipstream), with the captured CO₂ intended for enhanced oil recovery. Deliverables include the full engineering design package—such as process flow diagrams, equipment datasheets, and capital cost estimates—optimized for site-specific performance, operations, and construction practices.

ION Clean Energy, with Nebraska Public Power District, is conducting a FEED study to retrofit a CO₂ capture system on Unit 2 of the 700 MWe Gerald Gentleman Station in Nebraska. Using ION’s low-aqueous ICE-21 solvent, proven in prior DOE-funded projects to reduce energy use, solvent degradation, and emissions, the design will feature two parallel 350 MWe capture units. The project aims to decarbonize most of Unit 2 while maintaining maximum operational flexibility for the plant.
