Abstract: Techniques according to the present disclosure include capturing carbon dioxide from a dilute gas source with a CO2 capture solution to form a carbonate-rich capture solution; separating at least a portion of carbonate from the carbonate-rich capture solution; forming an electrodialysis (ED) feed solution; flowing a water stream and the ED feed solution to a bipolar membrane electrodialysis (BPMED) unit; applying an electric potential to the BPMED unit to form at least two ED product streams including a first ED product stream including a hydroxide; and flowing the first ED product stream to use in the capturing the carbon dioxide from the dilute gas source with the CO2 capture solution.

Abstract: A packing for capturing carbon dioxide (CO2) from a dilute includes at least one panel that includes a mesh material configured to be wetted by a CO2 capture solution and that defines a gas channel having a first dimension defined along a first direction and a second dimension defined along a second direction different than the first direction, the gas channel configured to receive a flow of CO2-laden gas from the dilute gas source in the second direction and contact the flow of CO2-laden gas with the CO2 capture solution on the mesh material.
