Molten salt has advantages over thermal oil
So far, thermal oils are used in parabolic trough power plants. Thermal oil flows into the absorber tube (dark pipe on the left). On these absorber tubes parabolic mirrors focus the light, here the solar radiation is converted into heat with a conventional power plant process steam is generated. In the now developed test system molten salt flowing through the absorber tubes.
