Sustainable Energy Solutions (SES), with their partners Brigham Young University, Electric Power Research Institute, and Tri-State Generation & Transmission Association, Inc., will further advance the external cooling loop version of their Cryogenic Carbon Capture™ (CCC) technology. SES has developed the CCC technology under previous research funded by an Advanced Research Projects Agency-Energy (ARPA-E) project, titled "Cryogenic Carbon Capture" (DE-AR0000101), the State of Wyoming, and others. Process improvements will be implemented that address issues discovered during the previous research. The CCC technology uses phase change to separate carbon dioxide (CO₂) and other pollutants from coal-derived flue gas. Cooling the CO2 to approximately -140°C results in the gas transforming into a solid without passing through the liquid phase (desublimation); the CO₂ is then separated from the remaining gas, pressurized, and melted. The CCC process is minimally invasive and highly efficient, effectively utilizing heat integration to achieve a 50 percent reduction in parasitic power demand compared to an amine absorption process. The team will improve key areas of the process through iterative design and experiment, culminating with a recommendation for improvements to be integrated into the existing skid-scale CCC-External Cooling Loop (ECL)™ system. Sustainable Energy Solutions will then integrate the improvements into the skid system and perform testing of the modified skid using simulated and actual flue gas for at least 500 continuous hours. Test results and process modeling will be used to update the techno-economic analyses of the CCC technology.
