Carbon Capture Costs: FEED & pre-FEED Cost Reports

Milton R. Young Station Unit 2 is conducting a FEED study to add a post-combustion CO₂ capture system using Fluor’s Econamine FG Plus™ technology to its lignite-fueled power plant in North Dakota. The design targets 3.6 million tonnes of CO₂ captured annually—twice the scale of the largest existing facility—while integrating advanced heat recovery, aerosol and solvent degradation controls, and cold-climate optimization to achieve the lowest levelized cost of capture at world scale. The study will deliver detailed design, cost, and performance data for financing, permitting, and final project scheduling.

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.

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.
