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.

Calpine Texas CCUS Holdings LLC, with Electricore Inc., is conducting a FEED study for a modular post-combustion CO₂ capture system at the Deer Park Energy Center NGCC plant in Texas. Using Shell’s commercial-scale amine technology, the system will capture 95% of emissions—about 5 MTPA—while maintaining low energy use and fast reaction rates. The study will include business case, techno-economic, life cycle, environmental, and public policy analyses, including environmental justice and job creation impacts.

Scope starts with the receipt of natural gas and fuel gas mixture from the existing Plant 01 and Plant 09 source and terminates with hydrogen (H₂) at the required specification and conditions to be used as fuel in the existing SMR unit. High concentration CO₂ from the ATR is captured and H₂ production from the proposed facility will replace the fuel gas feed to the primary reformer for heating. The facility capacity is based on the heating duty required to replace the current fuel source. The scope for the study involves the new ATR unit and associated downstream shift, CO₂ capture, and syngas purification unit. The project scope also includes an ASU to supply oxygen to the ATR unit.
