In Sensible Heat Storage (SHS) systems, thermal energy is stored by heating or cooling a liquid or solid as water, sand, molten salts, or rocks, with water being the cheapest option. The storage density of the latter system is 5–10 kWh/m 3 and 20–30 kWh/m 3 for cooling and heating applications respectively.
