Carbon Capture Costs: FEED & pre-FEED Cost Reports

Southern Company Services, with Linde Gas North America, is conducting a FEED study for a commercial-scale CO₂ capture system using Linde-BASF’s advanced aqueous amine technology at an NGCC plant of at least 375 MWe. The project will evaluate Alabama Power’s Plant Barry and Mississippi Power’s Plant Daniel to select the optimal host site, define project requirements, optimize process design, and deliver engineering packages along with a cost and schedule estimate within 15% accuracy. The study will build on prior feasibility work and site-specific testing.

Prairie State Generating Company is conducting a FEED study for a carbon capture facility on its 816 MWe Unit #2 in Illinois, using Mitsubishi Heavy Industries’ KM CDR Process™ with KS-21™ solvent. Designed to treat all flue gas from the unit, it would be the world’s largest post-combustion capture plant, compressing CO₂ for off-site sequestration. The project will leverage engineering support from Kiewit, Sargent & Lundy, and MHI.

Phillips 66, with Worley Group Inc., is developing the initial design for a commercial-scale CCS system at the Rodeo Refinery hydrogen plant, targeting over 90% capture efficiency and storage of about 190,000 tonnes of CO₂ annually. The project will evaluate three capture configurations—flue gas plus PSA tail gas, syngas plus flue gas, and flue gas only—selecting the most cost-effective option through a techno-economic analysis. The chosen design will be advanced to a level suitable for the next engineering phase, concluding with a final TEA for the selected CCS configuration.
