The aim of this work is to identify the potential of conventional solar systems for industrial process heating and determine the most suitable Swiss industrial sectors for its implementation. For this purpose, a detailed study of the Swiss industry energy consumption is carried out in order to obtain the amount of thermal energy consumed by process heating. Subsequently, this amount of energy is analysed for each industrial sector and those for which the energy demand could be provided by conventional solar thermal systems are sorted out. The theoretical potential for conventional solar thermal systems in the Swiss industry is therefore, estimated taking into account the most promising industrial sectors revealing an important implementation potential. Finally, the study also assese the potential for the implementation of solar process heat systems for different regions and cantons in Switzerland.
