A novel hydrogen storage material It is well known that world is running out of cheap and environmentally destructive fossil fuels in a near future. Fortunately, there are many technological options for transforming conventional fossil fuel based energy systems to less convenient but more abundant ones, such as hydrogen energy system In the present study, the quasi-binary system NaNH2 and NaBH4 was investigated with respect to phase formation and structural, thermal and vibrational spectroscopical properties, as well its capability as complex hydrogen storage material.
