DESERTEC - an international approach to use renewable energies at large scale — •Michael Düren — II. Physikalisches Institut, Justus-Liebig-Universität Gießen, Gießen, Germany

The DESERTEC concept combines solar power, wind power and other sources of renewable energy in a large and efficient electrical super grid that spans distances of several thousand kilometres. Fluctuations of the individual sources and loads are averaged out to a large extend. A special emphasis in this concept is given to a large network of solar thermal power stations that are located in deserts of the sun belt of the earth to maximize the yearly solar energy yield at a minimum of costs. The solar thermal power plants are equipped with large thermal storage capacity so that they can provide solar power day and night in accordance with the actual demand. The lecture will give an introduction into the basics of the physical and technological concepts and of the political and socio-economic implications of DESERTEC.
