ABSTRACT
This chapter provides an account of the use of magnesium to store hydrogen. Hydrogen can be stored in three different ways:
As a compressed gas in high-pressure tanks
As a liquid in Dewar, or tanks (stored at −253°C)
As a solid by either absorbing or reacting with metals or chemical compounds, or storing in an alternative chemical form
Magnesium hydride is the chemical compound MgH2, making it an alkaline earth hydride. It contains 7.66% by weight of hydrogen and is considered as potential promising hydrogen storage solution. Magnesium readily binds to hydrogen, and the idea is that you could take a tank filled with magnesium, pump in hydrogen, and then pump it out as needed to run your car.
