The U.S. Department of Energy’s (DOE) Office of Fossil Energy (FE) and NETL recently selected Susteon under DE-FOA-0002188 to receive $1 million funding to develop amine-doped solid sorbents catalyzed by ionic liquids that have the potential to increase the CO2 desorption rate by several orders of magnitude at desorption temperatures of 80-90°C. The anticipated benefits of this sorbent process are greater than 20 percent reduction in the energy required for sorbent regeneration, the potential to use waste heat for sorbent regeneration, increase in sorbent lifetime/stability due to lower regeneration temperature, and lower sorbent replacement cost due to the increased stability.
