CORMETECH Inc., in partnership with Global Thermostat LLC and Georgia Institute of Technology, is developing and testing a novel sorbent-air contactor composition with low pressure drop optimized for carbon dioxide (CO2) removal from ambient air. The project is focused on optimizing a monolith contactor to support a next-generation sorbent composition, linear poly(propyleneimine) (l-PPI), which offers advantages over benchmark poly(ethyleneimine) (PEI)-based sorbents for direct air capture (DAC). The novel approach will maximize the volumetric productivity of the DAC process while reducing the auxiliary power required to capture CO2 from air.
