Carbon Capture Costs: FEED & pre-FEED Cost Reports

Carbon capture costs from pre-FEED and FEED studies across power, cement, steel, natural gas, hydrogen and other industrial sectors. Browse capital (capex) and operating (opex) cost estimates from publicly available engineering reports, drill down into cost buckets and line items, and compare up to three projects side-by-side.

Description

Prairie State Generating Company is conducting a FEED study for a carbon capture facility on its 816 MWe Unit #2 in Illinois, using Mitsubishi Heavy Industries’ KM CDR Process™ with KS-21™ solvent. Designed to treat all flue gas from the unit, it would be the world’s largest post-combustion capture plant, compressing CO₂ for off-site sequestration. The project will leverage engineering support from Kiewit, Sargent & Lundy, and MHI.
