Abstract: The science of nanotechnology, now a days is leaving trademark prospects for better living. The motto of nanotechnology is “ever smaller and ever faster”. In this territory or field it has also encroached its arms into reach and development of hydrogen fuel cells. Carbon nanotubes have been intensively investigated for their fundamental technical importance for hydrogen storage. New techniques being researched may soon make hydrogen storage more compact safe and efficient. This is accomplished by using various approaches to shape carbon into microscopic cylindrical structures known as nanotubes and nanofibers, molecular cousins of “buck minister fullerene” (C60) or “bucky balls”. One of the critical factors in nanotubes usefulness as a hydrogen storage medium is the ratio of stored hydrogen to carbon.

Developing high-density hydrogen system, about 5-wt% that can release hydrogen at a temperature lower than 1000C has been the focus and the goal of researchers. The basic current approaches of hydrogen storage a compressed gas, liquid or in the form of solid hydrogen. A solid hydrogen storage system is reliable, sample to engineer and tremendously safer. Our objective has been to utilize the physisorption effect and generate chemisorption effect by introducing transition metals and hydrogen-bonding clusters is expected to allow us to tune the material for hydrogen sorption at desired temperature and pressures.

Carbon nanotechnology represents a new direction for solid hydrogen storage. Especially, if these materials can be altered to store large amounts of hydrogen at room temperature, samples have been doped and spectroscopic characterization was conducted. These impeded clusters are capable of bonding large amounts of hydrogen with favorable thermodynamic and enhanced kinetics, while the transition metals catalyze the hydrogen to react with clusters or nanotubes systems.
