How hot does the molten salt get when solar farms use it for energy storage?



  1. 0 Votes

    The molten salt is heated to about 1025-1050°F in order to most efficiently produce the steam needed for the solar farms. After collecting the sun’s energy, the salt is kept in a thermal storage tank until it is ready for use. Then it is moved to a heat exchanger, where it produces the steam to run a steam turbine, making electricity. Fun fact: Salt melts at 460°F and appears like water.
