Carbon Capture Costs: FEED & pre-FEED Cost Reports

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.

General Electric Gas Power, with Linde, Kiewit, and Southern Company Services, is conducting a FEED study for a “Generation 2” amine-based post-combustion CO₂ capture system at an existing NGCC power plant. Targeting at least 95% capture efficiency, the design will emphasize optimized integration, lower CCS costs, and flexible operation to complement renewable energy. The 18-month project will progress from multiple conceptual designs to a single configuration, culminating in a detailed design, technical viability assessment, techno-economic and life cycle analyses, and a business case evaluation.

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.
