Carbon Capture Costs: FEED & pre-FEED Cost Reports

A Front End Engineering and Design (FEED) study was undertaken to design an advanced CO2 Capture Unit (CCU) to produce 1000 tonnes per day of CO2 from the exhaust of three Once-Through Steam Generators (OTSG’s) at Devon Energy’s Jackfish 1 thermal in-situ operations and estimate the capital expenditure for the facilities within +/-15% accuracy. The process utilizes HTC Purenergy Carbon Capture Technology to capture CO2 from the OTSG exhaust gas using an aqueous chemical solvent in an absorber tower, after which the CO2-loaded solvent is passed to a stripper tower where the CO2 is released and the solvent regenerated. The study excludes downstream CO2 compression, dehydration, transportation and storage.

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.

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.
