Hydrogen

Magnesium hydride (MgH2), a binary inorganic compound with a hydrogen concentration of 7.66%, is a form of H2 storage. However, hydrogen desorption from MgH2 only occurs at a temperature of more than 400 degrees Celsius, which makes it harder to use for the needs of the hydrogen energy industry. The scientists from Tomsk Polytechnic University have attempted to reduce the desorption temperature by creating a new composite material, in which nano-sized aluminum powder was used as an additive to magnesium hydride.
