According to an article in Science Magazine, over $60M worth of ammonia is produced around the world. In fact, a vast majority of NH3 is manufactured as fertilizer, and its potential as a renewable energy source has only begun to be noticed in recent years. Curiously, the density as an energy-producing source is almost twice as much as that of liquid hydrogen. This places ammonia in the forefront of potential contenders to fossil fuels, next to renewables like wind, solar or geothermal energy.
