Carbon Capture Costs: FEED & pre-FEED Cost Reports

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.

Dastur International Inc., with Cleveland-Cliffs Inc., is designing a carbon capture system for the 5 mtpa integrated steel plant in Burns Harbor, Indiana, to capture 50–70% of CO₂ emissions from blast furnace gas. The system will combine a gas flow distribution network, a specialized conditioning process, and ION Clean Energy’s solvent-based capture technology with 90–98% efficiency, with water-gas shift reactors enabling higher capture rates. Dastur will lead overall plant integration and engineering, while ION designs the capture island and Dastur Energy optimizes design and energy performance.

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.
