Project Description

The overall goal of this project is to perform a front-end engineering design (FEED) study for the retrofit of Unit 2 (approximately 816 megawatt-electric [MWe]) of Prairie State Generation Company’s (PSGC) coal-fired power station in Marissa, Illinois with a post-combustion carbon dioxide (CO2) capture plant based on Mitsubishi Heavy Industries’ (MHI) advanced KM CDR process.

The purpose of the FEED study is to complete preliminary engineering and design work to support developing a detailed cost estimate for the cost of retrofitting CO2 capture at PSGC. University of Illinois, along with project partners Kiewit Corporation, Mitsubishi Heavy Industries America, Inc., and Sargent & Lundy, will perform multiple feasibility and design studies based on project-specific details in preparation for developing engineering deliverables. These studies will help define the scope of the retrofit project, based on project-specific decisions, technology-specific performance, site-specific requirements, and client-specific needs. Once the scope has been defined, detailed design will commence for the CO2 capture system and integration with the existing facility. Various design and engineering deliverables will be developed that will help define commodity quantities, equipment specifications, and labor effort required to execute the project. These FEED study deliverables will be prepared with the intent to develop an overall project capital cost estimate within a +/-15% accuracy.

Project Benefits

FEED studies for carbon capture systems at actual sites will provide the U.S. Department of Energy (DOE) with a more detailed understanding of carbon capture costs in a commercial application, thereby enabling DOE to better design its research and development (R&D) program to reduce those costs for similar carbon capture technologies being developed in its R&D portfolio.
