Abstract:
1. An apparatus for the capture of CO 2 from ambient air comprising: (a) an anion exchange material that captures CO 2 from a flow of ambient air; (b) a store-of liquid water; (c) a liquid water dispenser that delivers liquid water from said store of liquid water to said anion exchange material; (d) an outlet exposed to ambient air and downstream of said anion exchange material, through which air depleted of CO 2 exits the apparatus; and (e) a controlled environment in which said captured CO 2 is collected, wherein said controlled environment is (i) enclosed, (ii) comprises CO 2 -enriched air, (iii) is located downstream of said anion exchange material, and (iv) is located downstream of said store of liquid water, wherein said anion exchange material comprises a material that extracts CO 2 from air when dry and releases the extracted CO 2 captured by the anion exchange material at a CO 2 concentration higher than a starting concentration of CO 2 in said ambient air when exposed to said liquid water.
