Within the scope of the project, a pilot plant for the continuous and efficient provision of heat by means of solar thermal energy for processes in the medium temperature range (from 100-400°C) is being developed. With the help of a mathematical model of the pilot plant to be developed. With the help of a mathematical model of the pilot plant to be developed, optimised design and operating parameters for variable application and boundary conditions are to be determined. In parallel, a feasibility study and cost/benefit analysis are to be carried out in order to research the market potential on a regional basis. The aim is to determine the feasibility of heat utilisation for use in new regions.
