Abstract : It is known that hydrogen has the maximum energy content per unit weight in contrast to its low volumetric energy content that creates a considerable challenge for storage. Using hydrogen effectively on-board for mobile applications is still challenge. The big obstacle is how hydrogen can be stored in an efficient way and releases when needed. Different technologies are available now for hydrogen storage, but no one can reach the required conditions for real applications. Hydrogen can be stored as gas, liquid and or in solid form. But the target materials for hydrogen storage should be; lightweight and easily release hydrogen when required (at ambient pressure and temperature); and poses fast recharge/discharge kinetics with high impact safety. In this thesis some nanomaterials will be prepared and tested for hydrogen storage purpose. In comparison to any available fuel, hydrogen has the maximum energy content per unit weight in contrast to its fairly low volumetric energy content that creates a considerable challenge for storage. Using hydrogen effectively as an energy carrier depends on the available technology of storage and release when needed. In principle, the simple basic methods for hydrogen storage are compressed gas or liquefied hydrogen. Other under investigated methods are metal hydrides and carbon-based systems. The solution of permitting technology for the innovation of using hydrogen in transportation, and other portable applications is the solid hydrogen storage. Storing hydrogen in materials take place through three different mechanisms: • absorbed directly into the storage materials (absorption); • stored on the surface of storage materials (adsorption) and • chemical reaction. Materials that can be used for hydrogen storage are classified into four main groups depending on the storage mechanism, as follows: i- Metal hydrides, ii-Carbon-based materials, iii- Chemical hydrogen storage and iv- New materials and processes. The target materials for hydrogen storage should be; lightweight and easily release hydrogen when required (at ambient pressure and temperature); and poses fast recharge/discharge kinetics with high impact safety. In this thesis some nanomaterials were prepared and its ability as a potential candidate for hydrogen storage is investigated to search for additional enhancement in storage capacity thoroughly understanding of hydrogen-materials interplay.
