HPS-2: Demonstration of a solar thermal parabolic trough power plant and steam generation system using molten salt as the heat transfer fluid

Projects financed by the German Ministry of Economy and Energy (BMWI)

Renewable Power


The use of molten salt as a fluid carrier has important advantages. The operating temperature can be substantially increased, up to 500°C, and the plant is considerably simplified, as the same fluid is used for storage and as a heat transfer fluid. To validate the technology and identify possible problems during operation, a test loop will be built in Évora (Portugal), where the collector developed by TSK-FLAGSOL Heliotrough 2.0 will be installed.
