1. A method for producing a synthetic fuel from hydrogen and carbon dioxide, comprising:
extracting hydrogen molecules from at least one hydrogen compound in a hydrogen feedstock to produce a hydrogen-containing feed stream;
extracting carbon dioxide molecules from a dilute gaseous mixture in an atmospheric carbon dioxide feedstock, where extracting the carbon dioxide molecules comprises:
contacting the dilute gaseous mixture with a carbon dioxide capture solution,
precipitating at least some captured carbon dioxide into CaCO3 solids, and
operating a calciner to calcine the CaCO3 solids to produce a calciner product gas stream comprising a carbon dioxide-containing feed stream; and
processing the hydrogen-containing feed stream and the carbon dioxide-containing feed stream to produce a synthetic fuel, where at least some material used in at least one of the steps of extracting hydrogen molecules, extracting carbon dioxide molecules, or processing the hydrogen and carbon dioxide containing feed streams comprises material produced in another one of the steps of extracting hydrogen molecules, extracting carbon dioxide molecules, or processing the hydrogen and carbon dioxide containing feed streams.
