Das Projekt "COSY (EU-RTN): Complex Solid State Reactions for Energy Efficient Hydrogen Storage" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: GKSS Forschungszentrum Geesthacht GmbH in der Helmholtz Gemeinschaft, Institut für Werkstoffforschung,Werkstofftechnologie.Reactive Hydride Composites reveal great potential as hydrogen storage materials as they overcome the thermodynamic limitations hindering the use of light-weight complex hydrides. However, their sorption kinetics is still slow due to the fact that the hydrogen sorption process takes place within complex solid state reactions. It is aim of this project to explore the fundamental mechanisms involved in these reactions. For this, experimental studies on sorption kinetics, thermodynamics, crystal structure and electronic properties of the nano-structured materials are cross-linked to ab-initio calculations and theoretical modelling. The results will provide a basis to improve material properties and to develop new catalysts for hydrogen sorption. Finally, the optimization of synthesis methods and in particular the up-scaling of hydrogen storage materials preparation will be explored in collaboration with manufacturers.
Das Projekt "NESPA (Nanoengineered Superconductors for Power Applications) 2006-2010: Coordination of this europe-wide network consisting of 13 partners from universities, research institutes and industry" wird/wurde gefördert durch: Kommission der Europäischen Gemeinschaften Brüssel. Es wird/wurde ausgeführt durch: Leibniz-Institut für Festkörper- und Werkstoffforschung Dresden e.V..High temperature superconductors (HTS) have an enormous potential for significantly improving existing power systems, such as cables, motors, magnets and generators, because higher power densities and reduced losses can be achieved by replacing copper wires . Superconducting materials will also enable completely new technologies, such as fault current limiters. As examples for innovative applications, advanced energy systems for 'all-electrical' ships, off-shore wind mills and transportation systems should be mentioned. Although research on the materials aspects of HTS has been highly successful in the past, the development of low cost - high performance HTS materials remains a key factor for success and requires significantly more basic and applied materials re search, in order to bring these emerging materials to the market. The development of HTS materials for power applications is a highly multidisciplinary task involving chemistry, physics, materials science and electrical engineering. Currently, three quite different routes are addressed: (i) the construction and implementation of first 'real' industrial systems based on HTS materials, (ii) the development of 'coated conductors' that will result in an economic HTS wire production, and (iii) the controlled nano-engineering of highly textured bulk and thin film materials to enhance flux pinning and thus to improve the material performance. The planned RTN will strongly accelerate these developments by forming an international research team with leading experts i n different areas, who are willing and keen to train young researchers on a broad range of topics, from basic flux pinning investigations, advanced chemical processing of nano-engineered HTS materials or new concepts for low ac loss conductors, to industrially relevant subjects, such as IPR, quality management or cryogenic engineering. This will result in highly trained human resources that will be needed in the power sector in the very near future. - WP1 Nano-engineering of superconducting materials - WP2 Advanced electrical and structural characterization - WP3 New concepts for low ac-loss coated conductors - WP4 Industrial aspects of superconducting power application systems - WP5 Training and Transfer of Knowledge - WP6 Progress Monitoring, Management and Exploitation.
