Description
The retrofit of Unit 2 (816 MWe) of Prairie State Generating Station’s coal-fired power station with a capture plant using Mitsubishi Heavy Industries post-combustion CO2 capture technology.
The station is in Marissa, Illinois.
University of Illinois, along with project partners Kiewit Corporation, Mitsubishi Heavy Industries America, Inc., and Sargent & Lundy, performed multiple feasibility and design studies.
A 2022 feasibility study concluded that the project is not currently economic without enhancement to federal tax credits, and that Prairie State Generating Station might need to find a third party developer willing to secure funding.
