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.

Dastur International Inc., with Cleveland-Cliffs Inc., is designing a carbon capture system for the 5 mtpa integrated steel plant in Burns Harbor, Indiana, to capture 50–70% of CO₂ emissions from blast furnace gas. The system will combine a gas flow distribution network, a specialized conditioning process, and ION Clean Energy’s solvent-based capture technology with 90–98% efficiency, with water-gas shift reactors enabling higher capture rates. Dastur will lead overall plant integration and engineering, while ION designs the capture island and Dastur Energy optimizes design and energy performance.

A Front End Engineering and Design (FEED) study was undertaken to design an advanced CO2 Capture Unit (CCU) to produce 1000 tonnes per day of CO2 from the exhaust of three Once-Through Steam Generators (OTSG’s) at Devon Energy’s Jackfish 1 thermal in-situ operations and estimate the capital expenditure for the facilities within +/-15% accuracy. The process utilizes HTC Purenergy Carbon Capture Technology to capture CO2 from the OTSG exhaust gas using an aqueous chemical solvent in an absorber tower, after which the CO2-loaded solvent is passed to a stripper tower where the CO2 is released and the solvent regenerated. The study excludes downstream CO2 compression, dehydration, transportation and storage.
