NOVELTY - Method for integrated direct air capture of carbon dioxide for aqueous electrochemical reduction of carbon dioxide, involves (a) contacting input air stream with an electrolyte solution, where the input air stream comprises carbon dioxide to capture at least a subset of carbon dioxide from the input air stream to the carbon dioxide electrolyte solution, and (b) reducing at least the subset of carbon dioxide using the electrolyte solution to generate reduced carbon products, where during or subsequent to (b), the electrolyte solution is regenerated to capture additional carbon dioxide. USE - The method is used for integrated direct air capture of carbon dioxide for aqueous electrochemical reduction of carbon dioxide. ADVANTAGE - None given. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: a composition comprising a hydrocarbon mixture having carbon at an isotopic distribution of greater than -25% Δ 13carbon; and a system for integrated direct air capture of carbon dioxide for aqueous electrochemical reduction of carbon dioxide comprising a housing configured to contain an electrolyte solution, and computer processors that are individually or collectively programmed to (a) bring the electrolyte solution in contact with an input air stream comprising carbon dioxide to capture at least a subset of the carbon dioxide from the input air stream to the electrolyte solution, and (b) reduce the at least the subset of the carbon dioxide using the electrolyte solution to generate reduced carbon products, where during or subsequent to (b), the electrolyte solution is regenerated to capture additional carbon dioxide.
