The impact of climate change and increasing demand for energy requires the development of more sustainable energy technologies. Hence, thermal energy storage (TES) methods can contribute to more appropriate thermal energy production-consumption through bridging the heat demand-supply gap. In addition, TES is capable of taking over all elements of the energy nexus including mechanical, electricity, fuel, and light modules by means of decreasing heat losses, waste recovery, and energy-saving approaches to improving the system's performance.
