Abstract
Ammonia is well known to be the most commonly used chemical product in the world, usually used as nitrogen fertilizer. Ammonia can be liquefied at a slightly higher temperature as compared to hydrogen or natural gas; and even at room temperature, it can be liquefied at a pressure of about 1MPa. These merits support the fact that it can therefore be transported and stored more easily than hydrogen or natural gas. The ammonia we used was synthesized using the Haber Bosch method, using nitrogen gas collected from the air and hydrogen gas produced from fossil fuels, but its value is largely determined by the production cost of hydrogen. In the renewable energy society hoped for the future, low-cost hydrogen would be produced in order to ensure adjustment power, and ammonia is expected to play an important role as an excellent energy carrier. In this paper, an overview of the ability of ammonia as an energy carrier and some technologies for easily producing hydrogen from ammonia are introduced.
