Store H H in Materials A Mg. H 2 plex Com es id hydr “hydrogen economy”, in which hydrogen acts as energy carrier along with electricity, is being promoted as an ultimate solution to the world’s energy and environmental problems. A major challenge in commercialization of hydrogen energy is how to safely store the lightest hydrogen to a high energy density required for transportation application. In principle, hydrogen can be stored in gas-, liquid-, and solid-states. In comparison Metal nitride Chemical hydride with the former two forms, the solid state H storage via interaction between special materials and hydrogen possesses significant advantages on energy efficiency and safety issue. Therefore, a “gold rush” flurry of research activity has been directed towards the development of viable hydrogen storage materials for onboard application. Recently, the development of hydrogen storage material was significantly accelerated due to the increasingly strengthened interdisciplinary collaboration and enhanced participation & support of academia, industry and government. As a result, many new research branches associated with the discoveries of novel material structures/systems were established. These progresses, however, have not substantially narrowed the gap between achievable capability and that required for commercial onboard hydrogen application. A long-term high-risk/high pay-off basic research is still required, where the design and discovery of new, higher efficiency hydrogen storage materials is based on better understanding of the chemical and physical processes governing the hydrogen–materials interaction. Our Group Currently, our group focuses on the following hydrogen storage material systems: Our Research Mg-based composites, Complex hydrides, Metal nitrides, Chemical hydride Publications For details of our research, please refer to the latest publications.
