8 Mg-Based Hydrogen Storage MgH 2 is very promising for solid-state hydrogen storage Advantages (Mg): Low cost Lightweight Nontoxic High hydrogen storage capacity: 7.6 wt% in MgH 2 Problem Poor hydrogen sorption thermodynamics and kinetics (MgH 2 is very stable, T 300 C is needed to release H 2 ) Improvement? Tailor Mg into nanostructures? Add an appropriate transition metal catalyst
