The purpose of this project is to study the reaction rate during the absorption process of hydrogen in metal hydrides. Magnesium Hydride (MgH2) was chosen to be the metal hydride material for the storage medium. A car was modelled to calculate the theoretical consumption of hydrogen fuel during an hour drive at a constant cruising speed. The reaction equilibrium constant was derived from Vant Hoff equation with variable values of operating conditions. Then, the rate equation role was to determine the reaction rate of the absorption process of hydrogen by magnesium. This report contains new aspects, which show the conditions of obtaining hydrogenation rates and represents new approach of improvement of hydrogen absorption process in light metals, such as magnesium, that can provide promising results for the hydrogen storage applications.
