Ammonia production from carbon- and water-derived hydrogen

A system for producing ammonia, the system comprising:

• an electrolyzer configured to electrolyze water to form a first electrolysis stream comprising H2 and a second electrolysis stream comprising O2;
• an O2 liquefaction unit configured to liquefy at least a portion of the second electrolysis stream to form liquid O2;
• an O2 storage facility configured to store the liquid O2;
• an O2 gasification unit configured to gasify at least a portion of the liquid O2 to form a gasified O2 stream;
• a reformer configured to contact a reformer feed stream comprising hydrocarbons, at least a portion of the second electrolysis stream comprising O2, at least a portion of the gasified O2 stream, and an oxidant stream comprising O2 and N2 under conditions suitable to form a reformed stream comprising H2, CO, CO2, and N2;
• a water-gas shift reactor configured to contact at least a portion of the reformed stream with a water-gas shift catalyst under conditions suitable to form a shifted stream comprising H2, CO2, and N2;
• a carbon capture unit configured to separate at least a portion of the shifted stream to form a captured stream comprising CO2 and an ammonia production feed stream comprising H2 and N2;
• and
• an ammonia production unit configured to react at least a portion of the ammonia production feed stream comprising H2 and N2, and optionally at least a portion of the first electrolysis stream comprising H2, to form a product stream comprising ammonia.
