25 Claims

1. A method comprising:

generating a volume of chlorine gas using a chlor-alkali reactor;

generating a volume of dihydrogen using a carbon monoxide electrolyzer;

separating the volume of dihydrogen from an output stream, including an electrolyte, of the carbon monoxide electrolyzer;

generating a volume of hydrochloric acid using a hydrochloric acid reactor, the volume of dihydrogen, and the volume of chlorine gas;

acidifying the output stream of the carbon monoxide electrolyzer using the volume of hydrochloric acid;

converting, via the acidifying, a metal hydroxide in the output stream into a volume of a metal salt;

supplying the volume of the metal salt to the chlor-alkali reactor;

generating a volume of the metal hydroxide using the volume of the metal salt and the chlor-alkali reactor; and

supplying the volume of the metal hydroxide to the carbon monoxide electrolyzer to be used as the electrolyte.
