Overview
ABSTRACT
Solid state hydrogen storage under the form of magnesium hydride (MgH2) allows for the large-scale conversion of electrical energy, including renewable sources. Highly reactive nanostructured powders are obtained by the co-milling of MgH2 with transition metals. After compaction with expanded graphite, these powders allow for the production of composite materials with high storage capacity and very good kinetics of hydrogen sorption. As hydrogenation (dehydrogenation) reactions are strongly exothermic (endothermic), the development of performing tanks requires a state-of-the-art thermal management. Analytical and numerical tools have been developed in order to assist in the design of these storage systems.
