However, the low dielectric permittivity (∼2.2) and poor operating temperature (<105 C) hinder its applications in a high-temperature energy storage field. Moreover, the thermomechanical stability, dielectric strength, and lifetime will drop sharply in the elevated temperature when the temperature is above 85 °C [ [21], [22], [23] ].
The advantages of the two tanks solar systems are: cold and heat storage materials are stored separately; low-risk approach; possibility to raise the solar field output temperature to 450/500 C (in trough plants), thereby increasing the Rankine cycle efficiency of the power block steam turbine to the 40% range (conventional plants have a lower …
