The Institute of Engineering Thermodynamics at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt abreviated DLR) in Stuttgart, with further research facilities in Cologne, Ulm, Oldenburg and Hamburg, does research in the field of efficient energy storage systems that conserve natural resources, and next generation energy conversion technologies with a staff of 180 scientific and technical employees, engineers and doctoral candidates. The spectrum of activities ranges from theoretical studies to laboratory work for basic research and to the operation of pilot plants. These experimental and theoretical studies are accompanied by analysis studies to analyse the associated technological, environmental and economic potential. A tight network with the University of Stuttgart -especially with the Institute for Building Energetics, Thermotechnology and Energy Storage- and with the Helmholtz Institute Ulm at the University of Ulm is existing.
