Description
In May 2023, the U.S. Department of Energy selected the University of Illinois’ Illinois Sustainable Technology Center at Prairie Research Institute for a project to conduct an integrated capture, transport, and geological storage study of CO2 emissions at Dallman Unit 4.
DOE is allocating $4.7 million for this front-end engineering design study, which will explore the feasibility of building a 200-megawatt Linde-BASF advanced post-combustion CO2 capture system to process the Dallman Unit 4 flue gas and transferring the captured CO2 to be geologically stored in the Illinois Storage Corridor.
The project design is estimated to capture two million tons of CO2 per year.
This FEED study will leverage the existing DOE-funded 10 MWe large pilot at Dallman Unit 4. DOE cited the successful construction and operation of the Dallman Unit 4 pilot plant to demonstrate economic carbon capture technology and help enable commercialization of the technology.
