Research Objectives and Content
Mandatory reductions in emission of polluting gases from use of fossil fuel energy in industrial and transport activities are being negotiated and alternative energy sources and devices must be rapidly developed. Metal hydrides offer a safe alternative medium for transmission and storage of pollution-free hydrogen energy which can 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 commercialization has been retarded mainly due to high sorption temperatures.
Recent research has led to breakthroughs in Mg hydride technology by the introduction of small volume fractions of nano-scale particles of transition metals such as Ti, V, Cr, Mn, Fe and Nb Fe, Mn, V, Nb in metallic state or in oxide or hydride form. These innovations, in part achieved and patented by partners in this Network, have reduced H2 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.
Since the catalytic effects on H-sorption is generated by nano-particles of transition metals that are immiscible in Mg, nano-interface effects are clearly at work and will be studied. The state of bonding at the interphases between the nanoparticles and the Mg matrix and within these nano-particles will be considered in relation to the fundamental catalytic mechanisms affecting dissociation, adsorption and diffusion and desorption kinetics of H2 in Mg. This Network, which bring together collective pluri-disciplinary expertise from five nations in the EU zone and its Large Scale Research Facilities (ESRF and ILL), will investigate these fundamental mechanisms through gas-phase and electrochemical thermodynamic studies of nano-structured Mg hydride composites with various distributions of transition metal nanoparticles in pure and compound state with and without fluoride addition. Real-time H-sorption kinetics in the various nanocomposites will be examined by on-line diffraction methods at the ESRF and at the ILL in order to build on the recent progress towards cost-effective applications.
Currently, the single most important source of polluting gas emissions is the burning of fossil fuel products by consumers, transportation and other industries. In this global context, the development of clean energy technologies by this Network's industrial partners in the EU zone requires swift training of Ph.D. and Engineer Young Researchers (YRs) in application of Materials Processing Technologies to hydrogen storage and metal hydrides. Furthermore, as the information technologies (IT) and the internet in particular take more preponderant roles in all walks of life, battery technologies will require drastic improvement in energy capacity and delivery. The present Network will contribute to human resources requirements in this high-tech sector for future sustained economic growth of the EU zone and its global leadership position.
276 person-months of YR training are proposed and most of the YRs are likely to be hires by the industrial groups interested in this project.
Are you interested in joining a research training network as either a postdoc’ or Ph.D. student working on H-sorption in Mg composites?
