Carbon Capture Costs: FEED & pre-FEED Cost Reports

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.

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.

Analysis sets the design and cost-estimating basis for evaluating pulp and board mills with and without CCS. Two base cases are considered: a market pulp mill and an integrated pulp and board mill. Six CCS cases are evaluated, capturing CO₂ from the recovery boiler, multi-fuel boiler, lime kiln, or their combinations. The mills are assumed to be energy independent, with black liquor and bark burned to produce steam and electricity, and excess electricity exported to the grid. The CO₂ capture system uses post-combustion MEA technology with a 90% capture rate, and if on-site electricity is insufficient, an auxiliary boiler firing forest residues will supply the additional energy. 400,000 adt
