A carbon dioxide sequestering, fuel synthesis system comprises an electrolyzer to electrolyze saltwater for producing hydrogen and metal hydroxide. The hydroxide solution obtained by the electrolysis is passed to an osmotic exchanger, for flow within channels defined by gas permeable walls of the osmotic exchanger. External surfaces of the permeable walls are exposed to atmosphere fluid flow, wherein carbon dioxide of the atmosphere permeates the permeable walls for sequestering via reaction with the metal hydroxide. |
