Integration of Ultrahigh Capacity Sorbents into Direct Air Capture Systems
07/05/2021 - 03/31/2022
Direct air capture (DAC) of carbon dioxide (CO2) is a promising technology in reversing greenhouse gas emissions. DAC is possible through liquid and solid-sorbent technologies, but the lower energy costs for solid-sorbent technology can facilitate widespread, rapid deployment of DAC systems. Current DAC sorbents are limited in how much CO2 they can remove for a given amount of material, requiring large amounts of sorbent, increased system sizes, and higher cost. Mosaic Materials has developed an ultrahigh capacity sorbent using materials known as metal-organic frameworks (MOFs). Mosaic Materials’ MOF sorbent technology significantly outperforms other sorbents with respect to CO2 capacity, selectivity, and removal under extremely low CO2 concentrations. In this project, Mosaic Materials will integrate its MOF sorbent technology into an optimized air contactor to prove their technology’s ability to lower DAC costs.
