The heat engine-based systems that incorporate thermal storage with thermodynamic cycles for power/heat generation are covered in Chapters 3 and 636, including compressed air energy storage, liquid air energy storage, and pumped heat energy storage.
Thermal energy can be stored by simply changing the temperature of a material to higher level for heat storage or to lower level for cold storage. The amount of the stored energy can be calculated as the product of the specific heat capacity, the mass of the used material and the temperature difference.
Many mature and emerging energy storage technologies utilize combinations of thermal, mechanical, and chemical energy to meet storage demands over a variety of conditions. These systems offer the potential for better scalability than electrochemical batteries.
The candidates of thermal energy storage materials should satisfy thermal, physical, chemical, economic, and environmental requirements, described as follows: Chemical requirements: high chemical stability, no degradation, noncorrosive to the construction material, nontoxic, nonflammable, and nonexplosive; Economic requirements: cheap and abundant;
The development of thermal, mechanical, and chemical energy storage technologies addresses challenges created by significant penetration of variable renewable energy sources into the electricity mix.
Two of the key parameters of a sensible heat storage material that dominate its storage capability are the density and specific heat capacity; the higher value of the product of these two parameters leads to larger volumetric energy storage density with the unit of J m − 3 K − 1. 1.2.3.2.
