An electro-thermochemical cycling system for producing ammonia is provided that includes a reaction chamber having a metal compound input port, an anode suitable for oxidation in contact with the metal compound and configured for oxidation of hydroxide ions to water and oxygen, a cathode suitable for plating in contact with the metal compound and configured to electrolyze the metal compound to metal, a voltage source connecting the cathode and anode, a nitrogen port to the reaction chamber that combines nitrogen with the electrolyzed metal on the cathode to form a metal-nitrogen compound proximal to the nitrogen input, an atomic hydrogen port to the reaction chamber that combines with the metal-nitrogen compound to form ammonia, and an ammonia output port from the reaction chamber, where a metal compound input port inputs the metal compound to the reaction chamber according to a depletion rate of the metal compound in the reaction chamber.
