6. Thermal energy storage is a proposed method to store solar energy in between use.
This technology works by focusing solar arrays to heat up a molten salt (usually a mix of
Na+/K+/Li+/NO, ). Then the energy from the molten salt can be used later to run a steam
generator and produce work.
a) Suppose 10,000 tons of molten salt have been heated up to 800K (1 ton 907 kg). This
molten salt has a heat capacity of 1.5 J/g/K. How much heat is released from the salt when
it is cooled to 550 K?
b) Now suppose all of this heat is used to heat up water. What volume of water can be
heated from room temperature to 100°C using the heat released from the salt?
