1. A carbon capture method comprising:
removing carbon dioxide from a source by absorbing and chemically reacting gaseous carbon dioxide to form bicarbonate and/or carbonate in an aqueous solution;
supplying a catholyte comprising the aqueous solution at a cathode of an electrochemical reactor comprising an anode and the cathode separated by a bipolar membrane and applying a potential difference between the anode and the cathode to cause an electrochemical reaction yielding product gas comprising one or both of gas phase carbon dioxide and gas phase carbon monoxide, wherein the supplying of the catholyte at the cathode comprises supplying the aqueous solution in the absence of an additional supply of carbon dioxide gas; and
separating the product gas from the aqueous solution.
