Ammonia is an important chemical feedstock, and more than 80% of the synthesized ammonia is used to produce fertilizer. Ammonia is also being considered as an energy carrier and hydrogen source (1) because it has a high energy density (12.8 GJ m-3) and a high hydrogen content (17.6 wt%), (2) because infrastructure for ammonia storage and transportation is already established, and (3) because carbon dioxide is not emitted when ammonia is decomposed to produce hydrogen. If ammonia could be efficiently produced from a renewable energy source, such as solar or wind energy, problems related to the global energy crisis could…
