A cyclic process for the capture of carbon dioxide (CO2) directly from air utilizing a three-compartment electrolytic cell coupled with a hydroxide-based CO2 capture system as well as a carbonate-based CO2 capture system. Air is passed over a hydroxide compound in the hydroxide-based CO2 capture system to extract carbon dioxide from the air and produce a carbonate compound which is transferred to the carbonate-based CO2 capture system, where air is passed over the carbonate compound to extract carbon dioxide from the air and produce a bicarbonate compound. The bicarbonate is then passed into the three-compartment electrolytic cell where CO2, hydrogen and oxygen gases are separately released and the bicarbonate solution is transformed into a hydroxide solution that is reused in the hydroxide-based CO2 capture system. The flow of input compounds from one system to the other enables efficient operation of the direct air capture of carbon dioxide system.
