Storing thermal energy by changing the aggregate state of matter, usually from solid to liquid (e.g., ice bank and most conventional PCMs), is the most common method. Such a phase transformation normally takes place within a relatively narrow temperature interval (<8 K) and a small temperature hysteresis of a PCM (<3 K).
Phase change materials (PCMs) are considered one of the most promising energy storage methods owing to their beneficial effects on a larger latent heat, smaller volume change, and easier controlling than other materials. PCMs are widely used in solar energy heating, industrial waste heat utilization, energy conservation in the construction industry, and
TES systems can generally be divided into the following categories: sensible TES (STES), in which the thermal energy is stored by the temperature change of the storage medium (e.g., water, oil, sand, rock, etc.); latent TES (LTES), in which the thermal energy is primarily stored as latent heat due to phase transformation (e.g., phase change materials
