While solar heat for domestic and service applications has increasing market shares across Europe, solar process heat is very much in its infancy. In principle, the potential is enormous: about 30% of the total industrial heat demand is at temperature levels below 100°C which can be provided with commercially available solar thermal collectors. The international training seminar Solar Process Heat, which takes place as an official side event of Inter Solar Europe in Munich at 9 June 2011, will provide information and know-how on solar thermal system design for solar process heat installations. The seminar is organised by the O.Ö. Energiesparverband, the energy agency of Upper Austria, and the Fraunhofer Institute for Solar Energy Systems. It is held in the framework of the Intelligent Energy Europe project (IEE project) "Solar Process Heat" (So-Pro).
