AI Customer ServiceOver the last decade's magnesium and magnesium based compounds have been intensively investigated as potential hydrogen storage as well as thermal energy storage materials due to their abundance and availability as well as their extraordinary high gravimetric and volumetric storage densities.
Magnesium-based hydrogen storage alloys have attracted significant attention as promising materials for solid-state hydrogen storage applications due to their high hydrogen storage capacity, abundant reserves, low cost, and good reversibility.
Magnesium hydride and magnesium based systems are considered suitable candidates for hydrogen storage applications as well as due to their relatively high reaction enthalpy for thermal energy storage. Over the last fifty years a large number of scientific achievements were made to modify the hydrogen storage properties of this material family.
Pure magnesium has a theoretical hydrogen storage capacity of 7.6 wt.%, but its practical capacity is limited by the slow kinetics and high thermodynamic stability of MgH 2 . Alloying magnesium with other elements can alter the hydrogen storage capacity, depending on the type and amount of the alloying elements.
The researchers have improved the thermodynamic and kinetic properties of hydrogen absorption/desorption of Mg-based hydrogen storage materials through the addition of transition metal catalysts, doping of carbon composite catalysts, MgH 2 alloying, nanocrystallization, and construction of composite systems.
Therefore, in order to advance the large-scale application of magnesium-based hydrogen storage materials, researchers have employed various approaches to enhance the dissociation and recombination rates of hydrogen, improve hydrogen diffusion, and significantly enhance the catalytic performance of hydrogen sorption/desorption.
