Carbon materials have attracted many attentions as good candidates for hydrogen storage materials since the possibility of high amount of hydrogen storage using single-wall carbon nanotubes was reported in 1997. So far, many types of carbon materials have been studied, including carbon nanotubes/nanofibers, templated carbons with superior microporosity, and graphene. As shared awareness of precise measurement of hydrogen amount stored into materials is being established, it is clarified that hydrogen storage mechanism of carbon materials can be basically explained as physisorption on the surface. In order to achieve the storage amount of hydrogen at practical level, for example, the US DOE target value, new concept of hydrogen storage, such as chemical interaction or spillover effect, are currently considered. This review aims to introduce some basic concepts of hydrogen storage using carbon materials, and recent attempts for increasing amount of hydrogen stored under ambient conditions.
