Project Description

Coal-Seq III is a government-industry collaboration to study coal as a potential CO2 storage reservoir. Partners include Oklahoma State University, the Illinois Clean Coal Institute at Southern Illinois University and Higgs-Palmer Technologies. The project focused on the development and testing of three advanced geochemical and geomechanical simulation modules which increase the accuracy of simulating CO2 behavior in coals and shales. These modules address coal storage factors such as coal failure and permeability enhancement, matrix swelling and shrinking, and competition with water as an adsorbed phase on coals. These enhancements provide better means to predict geologic CO2 storage volumes.

Project Benefits

The focus of this project was on the technical/economic feasibility and application potential of carbon storage in coal seams. It has improved our understanding of carbon storage capacity estimation in coal seams, which contributes to better storage solutions for reducing CO2 emissions to the atmosphere. A special feature of Coal-Seq III is the development of improved simulation capability for injecting and storing CO2 in gas shales. This will enable investigators to better evaluate this abundant, poorly understood CO2 storage option, with a particular emphasis on the Appalachian Basin.
