Molten salt instead of thermal oil in solar thermal parabolic trough plants shall reduce the levelized electricity costs


An international consortium led by the DLR Institute of Solar Research, will build and operate a solar thermal molten salt parabolic trough test facility in Évora (Portugal). Members of the consortium are the German companies TSK Flagsol Engineering, Eltherm, Yara, and Steinmüller Engineering, the South African energy provider Eskom and the Portuguese University of Évora.

A unique feature of solar thermal power plants is the option to integrate a cost-efficient thermal storage which allows to produce electricity on demand, for instance even after sunset.
