Under the Industrial Carbon Capture and Storage (ICCS) Program, the U.S. Department of Energy (DOE) has collaborated with industry in cost-sharing arrangements to demonstrate technologies that will capture CO2 emissions from industrial sources and either store or beneficially re-use them. The technologies included in the ICCS program have progressed beyond the research and development stage to a scale that can be deployed into commercial practice within the industry.The Illinois ICCS project presents a unique opportunity to gather crucial scientific and engineering data to increase understanding of large-scale CO2 storage in saline formations.
