Description

Mandatory reductions in emission of polluting gases from use of fossil fuel energy in industrial and transport activities are being negotiated between Europe, the USA, Japan and the developing countries and alternative energy sources and devices must be rapidly developed. Metal hydrides offer a safe alternative for transmission and storage of pollution-free hydrogen energy to be used in fuel cells, batteries and other applications. Mg-based metal hydrides with high volumetric energy density, low cost and high abundance are the best candidate but commercialisation has been retarded mainly due to high sorption temperatures. In the past two years, research in Canada and Germany have led to breakthroughs in Mg hydride technology by the introduction of small volume fractions of nano-scale mixed-valence oxides such as Cr_2O_3, Fe_3O_4, Mn_2O_3 and V_2O_5 and/or nano-particles of Cr, Fe, Mn, V, Ti, Nb in their metallic states. These innovations, in part achieved and patented by partners in this Network, have reduced H_2 de-sorption times below 300 C to 5 minutes and are considered for application by GFE and other corporations in collaboration with teams of this Network.

It is highly original that the most dramatic catalytic effects on H-sorption are generated by nanoparticles of transition metals that are immiscible in Mg and exhibit mixed valency (such as Fe, V, Cr, Mn). However, the state of bonding in these nano-particles and their fundamental catalytic mechanisms on the dissociation, Adsorption, diffusion and de-sorption kinetics of H^2 in Mg are not known. It is therefore of urgent fundamental and industrial interest to Perform a comparative study of the effects. This Network proposes to bring together collective pluri-disciplinary expertise from five nations in the EU zone and its Large Scale Research Facilities (ESRF and ILL) to investigate these fundamental mechanisms and to build on the recent progress towards cost-effective applications.
