Energy and economic evaluation of combined sensible-latent thermal energy storage …
This strategy leads to a better usage of both the storage methods i.e., higher amount of energy stored in low-cost storage material that reduces system cost compared to that of latent TES. Further, the lower portion of PCM at the top of rocks can stabilize the outlet temperate of fluid during the discharging process.

Thermal Energy Storage | Thermal Energy Group
Our team is developing thermochemical material (TCM)-based thermal energy storage. In a TCM, energy is stored in reversibly forming and breaking chemical bonds. TCMs have the fundamental advantage of significantly higher theoretical energy densities (200 to 600 kWh/m3) than phase change materials (PCMs; 50 to 150 kWh/m3).
