"Green" Ammonia's Future as a Marine Fuel

Ammonia, the same pungent solution used in fertilizers and cleaning agents, may one day be the key to transporting renewable energy around the world. There are currently a number of government and corporate projects assessing the feasibility of converting excess renewable energy from sources like wind, solar, tidal and nuclear into ammonia and then back into usable energy.In its purist form, ammonia or NH3 is composed of one nitrogen and three hydrogen atoms making it an ideal candidate to chemically bind excess renewable energy. Like several other chemical compounds, ammonia can be transported by chemical tanker in liquid form to end-users. Based on its near ambient liquification point, it may be more appealing to transport ammonia over longer distances than hydrogen.
