Due to the dispersed rural population, the power voltage in rural areas fails to sustain a normal operation in high-power heating appliances. Moreover, when the temperature drops, the growing season for agriculture has already concluded, and the supply of electricity for rural areas may not be as essential as it is in the growing season
In contrast, High temperature aquifer thermal energy storage (HT-ATES) uses deeper aquifers and a larger range operating temperature (between 30 and 90 C). Some active HT-ATES projects show the aim of reservoir depth even over 1000 m and reservoir temperature is over 50 °C ( Fleuchaus et al., 2020 ).

Compressed air energy storage, high-temperature TES, and large-size batteries are applied to the supply side. Small size batteries and TES are technologies coupled to the demand side. In addition to the complexity of the demand/supply sides, other design factors must be addressed in order to enjoy efficient, cost-effective, and clean
On the other hand, the stable dielectric and energy storage performance of PTCBI/PEI blends at high temperature are expected because the PEI and PTCBI both exhibit the good heat stability.
