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? 6:37 1/29/ Home End Insertarrow_forward5.
