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.

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.

Linde Inc., with Linde Engineering Americas, Linde Engineering Dresden, and Svante Inc., is completing an initial engineering design for a commercial-scale CO₂ capture plant at its steam methane reforming hydrogen facility in Port Arthur, Texas. Using Svante’s VeloxoTherm™ solid adsorbent technology, the system will capture about 1 million tonnes of CO₂ annually at ≥90% efficiency while producing 99.97% pure “blue” hydrogen. The design will include ISBL units for flue gas conditioning and CO₂ purification, OSBL components, and a techno-economic analysis of capture costs and hydrogen production economics.
