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.

The Red Trail Energy (RTE) ethanol facility in Richardton, North Dakota, is implementing a CO₂ capture and liquefaction system designed by Trimeric. The system captures CO₂ from fermentation, compresses it to ~350 psig, dehydrates and liquefies it using an ammonia refrigeration loop, and purifies it via distillation to remove oxygen and other gases. The liquid CO₂ can be stored for sale or geologic sequestration. The facility is designed to process 587 tonnes/day (scalable to 675 tonnes/day), with nearly complete CO₂ recovery.

Calpine Texas CCUS Holdings LLC, with Electricore Inc., is conducting a FEED study for a modular post-combustion CO₂ capture system at the Deer Park Energy Center NGCC plant in Texas. Using Shell’s commercial-scale amine technology, the system will capture 95% of emissions—about 5 MTPA—while maintaining low energy use and fast reaction rates. The study will include business case, techno-economic, life cycle, environmental, and public policy analyses, including environmental justice and job creation impacts.
