2). The nanocomposite materials encompass a catalyst and composite chemical hydrides at the nanometer scale.
In this study, we will review our experimental results on hydrogen storage properties and characterization of hydride-magnesium amide (MH-Mg(NH2)2), hydride-ammonia borane (MH-NH3BH3) and hydrideammonia (MH-NH3) systems.
(2) NaH-NH3BH3 composite material desorbed 11 mass% of hydrogen below 90°C without emission of NH3 and foaming.
(3) LiH-NH3 system desorbed 6 mass% of H2 at room temperature.
(4) H2 and N2 were generated by the decomposition of NaNH2 at 400°C.
(2) NH3 shows promise for the application of H2 energy carrier because the cost of H2 in NH3 is below 1/4 of the supply cost of H2.
