Carbon Capture Costs: FEED & pre-FEED Cost Reports

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.

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.
