Thermal Energy Storage

2.1 Sensible-Thermal Storage. Sensible storage of thermal energy requires a perceptible change in temperature. A storage medium is heated or cooled. The quantity of energy stored is determined by the specific thermal capacity ((c_{p})-value) of the material.Since, with sensible-energy storage systems, the temperature differences between the storage medium

Energy Storage

While solar energy may be the leading renewable energy source, storage challenges have limited its adoption by utilities. Thanks to innovations in thermal energy storage in MWh quantities, solar thermal energy has become more feasible for large-scale applications. Thermal energy can be stored in sensible, latent, or chemical form.

Phase change material-based thermal energy storage

Although the large latent heat of pure PCMs enables the storage of thermal energy, the cooling capacity and storage efficiency are limited by the relatively low thermal conductivity (∼1 W/(m ⋅ K)) when compared to metals (∼100 W/(m ⋅ K)). 8, 9 To achieve both high energy density and cooling capacity, PCMs having both high latent heat and high thermal
