Hydrogen has been recognized as a clean and sustainable fuel. However still many problems have to be to be solved in area
of generation, transport and storage of this fuel for future hydrogen based economy to be realized. Some of our research
in this area will be presented. Reaction of water with activated aluminum powder is consider as one of the methods to generate
hydrogen. The reaction produces also aluminum hydroxide (Al (OH) 3 or AlOOH) as the byproduct; these compounds change to
alumina (Al2O3) after calcination process, and alumina can produce aluminum [1, 2]. Hydrogen production rate can be increased
if effective surface area of aluminum exposed to oxidation is increased. We found that microstructural refinement can be used
to promote the reaction and allow major increase of the production of hydrogen. The addition of water soluble salts (potash or
salt) also allow to increase the oxidation rate and hydrogen generation. However, we established that presence of salt has smaller
influence than microstructural modifications. The storage of hydrogen will also require structural modification of the storage
system. One of storage system that was developed by our team will be discussed . We designed a Pd-graphene composite for
hydrogen storage with spherical shaped nanoparticles of 45 nm size homogeneously distributed over a graphene substrate. This
new hydrogen storage system has attractive features like high gravimetric density, ambient conditions of hydrogen charge and low
temperature of the hydrogen discharge. The palladium particles produce a low activation energy barrier to dissociate Plenarythis
helps delaying the formation of metallic clusters and can improve hydrogen storage in metal graphene systems.

Jerzy. A. Szpunar, joined the Department of Mechanical Engineering at the University of Saskatchewan in August 2009, as Tier I Canada Research Chair. He came from McGill University where he was Professor of Materials Science and Birks Chair in Metallurgy. His research interests extend to various areas of materials related investigations. More recently his research has focused on environmentally friendly energy generation, in particular the extraction and purification of hydrogen, accident tolerant nuclear fuel and research on advanced materials for Generation IV nuclear reactors. His research supports also various clean energy programs and research on more safe and secure materials for oil and gas transportation. Dr Szpunar has a strong record of research productivity. 40 PhD students and 27 MSc. students graduated under his supervision. He is an author and co-author of more than 900 research papers.
