Ammonia is a kind of material that offers a path to turning hydrogen into a liquid fuel. Ammonia's energy density by volume is nearly double that of liquefied hydrogen, making it far easier to store and transport. Formic acid with its high volumetric concentration of H2 (53 g L -1 ) is a potential liquid organic hydrogen carrier (LOHC). Formic acid is a renewable hydrogen carier, it can be produced from carbon dioxide via direct catalytic hydrogenation. The most promising catalysts for FA selective dehydrogenation are based on nobel metals such as ruthenium and iridium. Ammonia borane (AB), BH3NH3, is a stable solid at room temperature, melts at a temperature 110 -114 C. It is a promising chemical hydrogen storage material for use in fuel cells for automotive industry because of its high H2 intrinsic material capacity and the exothermicity of the dehydrogenation reaction.
