Summary:A novel chemical cycle for producing and capturing ammonia using nitrogen and hydrogen sulfide containing feedstocks is presented. An example of this cycle may start with the reaction between lithium nitride and hydrogen sulfide containing materials to form both lithium sulfide containing material and ammonia, where the produced ammonia is separated and captured. Metallic lithium may then be extracted high temperatures from said lithium sulfide containing material and then may or may not be separated from the said lithium sulfide containing material and other byproducts. The said extracted metallic lithium containing material may then be reacted with nitrogen containing feedstock to form lithium nitride containing material to complete the cycle.
