Overview on Hydrogen Absorbing Materials

Abstract

Hydrogen is a promising and clean fuel for transportation and domestic applications, but is difficult to store. Many systems have been investigated in order to improve the maximum hydrogen storage capacity (reversibility), high kinetics, moderate equilibrium pressure and/or decomposition temperature, and better cyclability. In this chapter, a review of studies related to stability of Zr-based Laves phase system as well as in-situ neutron diffraction investigation, the kinetics of TiFe, surface treatment of LaNi5 system, mechanically alloyed Mg-based hydrides, and graphite nanofibers are reported.
