Susteon Inc., in partnership with the University of Wyoming (UWy), is working to develop solid sorbent materials that have much higher working carbon dioxide (CO2) capacity and can be regenerated at lower temperatures than current state-of-the-art materials. Structured sorbent beds can be constructed using these sorbents for low pressure drop operation to achieve reduced costs for direct air capture (DAC) of CO2. The project aims to develop amine-doped solid sorbents catalyzed by a novel ionic liquid (IL) that have the potential to increase the CO2 adsorption and desorption rate by several orders of magnitude as compared with non-catalyzed sorbents.
