Magnesium hydride is the chemical compound with the molecular formula MgH2. It contains 7.66% by weight of hydrogen and has been studied as a potential hydrogen storage medium.
For comparison, one cubic meter can contain 45 kg of hydrogen pressurized at 700 atm, 70 kg of liquid hydrogen, or up to 106 kg of hydrogen bound in magnesium hydride.
Magnesium hydride is also investigated for use in thermobaric weapons and incendiary weapons, standalone or as a mixture with a solid oxidizer; China tested a (non-nuclear) "hydrogen bomb" using the substance. It can be also used in emulsion explosives as a source of bubbles and additional fuel. It can be added to improve heat release of aluminized explosive compositions and to improve burn rate of propellants. Wikipedia
