Hydrogen is considered as a clean and efficient energy source due to its abundance, non-polluting nature, and light weight. The hydrogen storage materials are required to have high volumetric and gravimetric capacity. Metal hydrides are the most promising materials for hydrogen storage purposes. The production of large specific surface area nanostructured metals for hydrogen storage was studied. The large surface area is expected to yield faster hydrogen up-take during charge and also faster desorption during hydrogen release. Among various fabrication techniques electrodeposition has the clear advantages of high growth rates and the use of simple experimental set-up to produce nanostructured materials. Palladium is the ideal candidate to study hydrogen storage kinetics because its bulk hydride properties are well-characterized. This is an abstract of a paper presented at the AIChE Annual Meeting (Salt Lake, UT 11/4-9/2007).
