Learn MoreSensible heat storage involves storing thermal energy in various forms such as liquid or solid media (e.g. water, sand, molten salt, or rocks) by heating them using the heat transfer fluid [25]. This method is one of the most cost-effective among TES technologies [ 9 ] due to lower temperature differences between the storage medium and the surroundings.
