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.

Membrane Technology and Research Inc., with Technology Centre Mongstad, Dresser-Rand, Trimeric Corporation, and WorleyParsons/Advisian, is scaling up its advanced Polaris™ membranes for post-combustion CO₂ capture and testing them at engineering scale at TCM in Norway. The Polaris membranes, about 20 times more permeable than prior commercial versions, use a patented selective recycle design to boost CO₂ concentration in flue gas and lower capture costs. The project will design, build, and operate a modular membrane system for a six-month field test, including performance verification, steady-state operation, techno-economic updates, and integration studies with advanced compression technology.

ION Clean Energy, with Nebraska Public Power District, is conducting a FEED study to retrofit a CO₂ capture system on Unit 2 of the 700 MWe Gerald Gentleman Station in Nebraska. Using ION’s low-aqueous ICE-21 solvent, proven in prior DOE-funded projects to reduce energy use, solvent degradation, and emissions, the design will feature two parallel 350 MWe capture units. The project aims to decarbonize most of Unit 2 while maintaining maximum operational flexibility for the plant.
