Hydrogen storage describes the methods for storing H2 for subsequent use. The methods span many approaches, including high pressures and cryogenics, but usually focus on chemical compounds that reversibly release H2 upon heating. This is commonly known under hydrogen storage. One of the most interesting research topics of major interest for industrial application is the field of metal hydride systems for storing hydrogen in large quantities and so to enable the use of hydrogen as fuel in automobiles. Here, extensive work has been done to investigate the magnesium based alloys hydride system as possible hydrogen storage container. However, despite the large hydrogen loading capacity the major drawback here is the fact that the hydrogen loading and deloading process occurs with very slow kinetics. Therefore, investigating the palladium hydride system, as palladium absorbs large quantities of hydrogen and offers in terms of kinetic behaviour much better conditions, is in the scope of interest. However, running the hydrogen fuel economy on the basis of palladium is fairly impossible, since palladium is highly expensive. Therefore, it is quite sensible to reduce the quantity of palladium by either the use of nanotechnology and/or the use of alloys such as palladium/nickel/cobalt etc. The aim of our project is to understand the mechanism by which hydrogen enters the palladium bulk and how does the inner metal lattice of palladium support the incorporation of hydrogen. To study the palladium crystal structure is found to be significant to determine the key factors to increase loading capacity and to even enhance loading and deloading kinetics. Once these issues are fully resolved, of crucial interest is then the study of palladium - nickel based alloys.
