Solar Thermal Energy Utilization. German Studies on Technology and Application -

. .

Résumé :
The German R+D programm Solares Testzentrum Almeria (SOTA) provides the scientific basis for the realization of advanced solar technologies including facility modifications, component tests and new lines of development. One of the working packages, WP 300, adresses the Scientific Support by the performance of preparatory studies, exploratory laboratory activities and qualified expertise. Universities, Research Institutes and Company R+D Enitities in Germany are enabled to treat the following aspects: - Meteorological, system and cost investigations, - Development of important components as concentrator, receiver, storage, - Utilization of solar energy for process heat and chemical reactions. In 1991 the studies covered developments of terminal concentrators, receivers, integrated receiver/reactors, and solar chemistry processes. The reports of the activities were finalized recently and collected in the present volumes. The final reports were printed as received under the responsibility of the authors.
