Review on the Materials for Hydrogen Adsorption & Storage

Many Efforts have been made in order to use new and renewable energy instead of fossil fuels and as a supply of the needed clean energy. One of the most interesting options which attracts researches’ attention, is one of the most common element in the earth, Hydrogen. For using the hydrogen as a source of energy, there are two important points which should be considered carefully, first is the technology of production of hydrogen and second the storage of hydrogen. In this article the hydrogen adsorbent materials are introduced. The metallic hybrids, Nitrogen based materials, Mg-based materials and carbon based materials are four main groups of hydrogen storage materials that attracts many attentions. Faradic parameter described theoretically the capability of hydrogen storage. Based on the before investigation, high current density, lower voltage and high discharge rate in carbon based materials especially in carbon nano tubes increase the capability of hydrogen storage. Increasing the storage capacity of hydrogen will help human being to access the clean fuel for all uses in energy.
