This book deals with advanced information regarding the technology of hydrogen storage. Throughout the globe, a better and safer alternative for petroleum is in much demand because of growing climatic problems like global warming and also perennial energy shortfall. Hydrogen has come up as a very capable, cost productive, inexhaustible, and clean energy substitute. Nevertheless, the storage of hydrogen remains a serious concern, mainly for the use in automobiles which run on proton-exchange membranes (PEMs) used fuel cells. Consequentially, scientific organizations, by using nanotechnology, have started discovering new hydrogen preservation materials. This book talks about the varied nano-structured assets used for utilization in hydrogen storage, including chemical and physical aspects. The matters discussed in the book are analytic designs, fusion, transforming, constructions, qualities and use of nanomaterials in hydrogen storage systems.
