Teong & Zhang (2023): Direct capture and separation of CO2 from air

Siew Ping Teong, Yugen Zhang IN: Green Energy & Environment, https://doi.org/10.1016/j.gee.2023.06.005

Current DAC methods are still based on solid absorbents or alkali solutions approaches which have low capture efficiency and low energy efficiency. This highlight proposed a promising CO₂ capture technology, an electric energy driven closed-loop system for the direct removal of CO₂ from ambient air which are based on two individual technologies: Polyam-N-Cu hybrid system promoted CO₂ capture with ocean as anthropogenic CO₂ sink and a chloride-mediated electrochemical pH swing system to remove CO₂ from oceanwater.
