1. A method for producing acetic acid from carbon dioxide comprising:
receiving carbon monoxide produced by reduction of carbon dioxide in one or more carbon dioxide reduction electrolyzers and hydrogen produced by a water electrolyzer;
directing a first feed stream comprising carbon monoxide from the one or more carbon dioxide reduction electrolyzers and hydrogen from the water electrolyzer to a methanol synthesis reactor;
synthesizing methanol in the methanol synthesis reactor;
directing a second feed stream comprising methanol from the methanol synthesis reactor and carbon monoxide from the one or more carbon dioxide reduction electrolyzers to an acetic acid synthesis reactor; and
synthesizing acetic acid in the acetic acid synthesis reactor.
