Complex hydride
Appearance
A complex hydride is a molecule such as sodium aluminum hydride (NaAlH) or lithium borohydride (NaAlH4) which readily accepts or gives up hydrogen atoms.
Applications
Such a material is being examined for its potential to store hydrogen for use as a fuel. A material such as lithium borohydride is capable of storing hydrogen with the same density as that of methane, without requiring the energy input methane requires to release the hydrogen as free atoms.
