Transformational Sorbent-Based Process for a Substantial Reduction in the Cost of CO<sub>2</sub> Capture

InnoSepra’s project, “Transformational Sorbent-Based Process for a Substantial Reduction in the Cost of CO2 Capture,” utilized computational tools, materials characterization, and lab and pilot-scale testing to optimize previously identified materials to determine their performance under post-combustion capture conditions. InnoSepra utilized the test results to determine the energy required for regeneration and to develop a process design/analysis to demonstrate the application of developed materials for post-combustion capture. A techno-economic analysis was performed to fully assess the potential of the materials for post-combustion capture. InnoSepra also updated the State Point Data Table and completed the environmental, health, and safety (EH&S) Risk Assessment. The InnoSepra CO2 capture technology has the potential for a significant reduction in the CO2 capture cost for the power plant and industrial flue gases. • It is possible to obtain very high recovery (90-95%) and high purity (>98%) CO2 with physical sorbents while meeting the EOR/sequestration product specifications. • The technology has the potential to reduce the thermal parasitic power by more than 65%, and the capital required by about 45% leading to about 45% reduction in the CO2 capture cost for the coal-based power plant flue gas. • After demonstration at the pilot scale and further process optimization, the process has the potential for a capture cost of around $40/MT with no increase in Levelized Cost of Electricity (LCOE) and with very little loss in power output.
