La generación de energía necesaria para satisfacer la creciente demanda global no debe comprometer el medio ambiente ni el futuro del planeta.. Hoy en día las energías renovables se han identificado como potenciales alternativas a los combustibles fósiles que perjudican a la planta con emisiones de CO2.. Después, solar energy is seen as the most versatile and the largest source of heat and electricity for the future globally.
Sin embargo, as solar is an intermittent source and has variable outputs, energy storage technologies are required in order to facilitate the heat and electricity demands from solar energy and to ensure that the supply matches these demand. Most importantly, the high-efficiency utilization of solar energy necessitates considerable advancement in energy storage technologies and materials to overcome its intermittent nature.
