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.

The Peterhead CCS Project in Aberdeenshire, Scotland, was designed to demonstrate the world’s first commercial-scale post-combustion CO₂ capture from a gas-fired power station. Using amine-based CANSOLV technology, it aimed to capture around one million tonnes of CO₂ annually from one turbine at SSE’s Peterhead Power Station, compress and condition it, and transport it via a new offshore pipeline for injection into the depleted Goldeneye gas reservoir over 2 km beneath the North Sea. The FEED study defined project scope, refined CAPEX and OPEX estimates, and assessed cost uncertainties, providing a basis for the Execute phase while also documenting budget performance and emergent costs during FEED.

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.
