5 Magnesium Hydride Uses: Facts You Should Know!

Magnesium hydride is one type of hydride where hydrogen gets attached to an alkaline earth metal like magnesium. The chemical formula of magnesium hydride is MgH2.

The uses of magnesium hydride are given below:

  • Hydrogen storage
  • Energy storage system

Hydrogen storage

  • Magnesium hydride is used a good source for hydrogen storage.
  • The low density and reactivity of magnesium hydride facilitates to exhibit this property.
  • Magnesium hydride is also used to produce hydrogen gas.
  • When treated with water, MgH2 decomposes to give hydrogen gas.
  • MgH2 + H2O ——–> 2H2 + Mg(OH)2

Energy storage system

Magnesium hydride is used as a thermal energy storage system because during hydrogenation -dehydrogenation process, it can retain with high enthalpy.

Conclusion

Magnesium is an abundant metal on earth with some unique properties. Some hydrides are used as good reducing agent. Magnesium hydride is a crystalline solid substance which gets decomposed in water.
