Hydrogen Onboard Storage Technologies for Vehicles

Over the past few years, significant progress has been made in hydrogen-powered vehicles. Most of the development work focused on the powertrain and its integration into the vehicle. Currently, one of the key technologies that determines the development of the automotive industry are on-board hydrogen storage systems. Without efficient storage systems, the using of hydrogen to drive motor vehicles will be difficult to achieve. The physical storage density limits of compressed and liquid hydrogen have been more or less reached, whilst there is still potential in the development of various hydrogen storage materials. This chapter presents methods and problems related to hydrogen storage. Some of discussed technologies are immature, however this does not rule out for them future use therefore, their opportunities and foreseen potential were also presented.
