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.

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.
