How does molten salt affect energy levels?

In direct storage systems, the molten salt is directly the HTF of the solar field, which is directly stored in the tanks without any heat exchanger. Thus, molten salt changes its temperature—and therefore its energy level—from cold to hot. These two energy levels are contained in two different storage tanks.

Can molten salt be used as an energy collector?

The benefit of using molten salt as both the energy collector that creates steam and the energy storage mechanism, however, is that it eliminates the need for expensive heat exchangers to go between different fluids.
