Ammonia consists of 17.6 wt % of hydrogen, and thereby, it can be used as an indirect hydrogen storage compound . Moreover, ammonia's energy density is approximately 4.32 kWh.L -1 , showing a capacity equivalently to methanol and almost double than that of liquid hydrogen . Recently, automobiles operating on pure ammonia and gasoline-ammonia fuel modifications are being hypothesized and near to be prototyped . An important advantage of using pure ammonia is the resulting diminished reliance on fossil fuels by changing to a "sustainable fuel source" that can be manufactured synthetically . Soon synthetic lowcarbon fuels will be needed as a response to the current environmental emergency, and ammonia is among such synthetic fuels.
