Abstract. Concentrated Solar Thermal Power has an advantage over other renewable technologies because it can provide 24-hour power availability through its integration with a thermal energy storage system. Phase change materials in the form of eutectic salt mixtures show great promise as a potential thermal energy storage medium.
MSRs also use molten salt for power production, operating using molten salt as a circulating fuel. These energy technologies have many advantages, such as higher efficiencies, safer operation, and economic success.
A major problem with heat storage with PTC and oil circuit is the limited temperature range between the oil input and output temperatures (the maximum being 100 K). For molten salt-solar tower heat storage, the temperature difference is nearly 300 K.
Advantages and disadvantage. The main advantages of molten salts are their high energy density, between 70 kWh/m 3 to 200 kWh/m 3, an operating temperature up to 565 °C, high cyclability, more than 10,000 cycles and a lifetime longer than 20 years [66].
