Why are thermochemical storage materials so expensive?

Materials for thermo-chemical storage (TCS) are also expensive as they have to be prepared (e.g. pelletised or layered over supporting structures). Also expensive are the containers and the auxiliary TCS equipment for both heat and mass transfer during energy charging and discharging.

Can thermal energy be stored in a heat storage media?

Thermal energy (i.e. heat and cold) can be stored as sensible heat in heat stor-age media, as latent heat associated with phase change materials (PCMs) or as thermo-chemical energy associated with chemical reactions (i.e. thermo-chemical storage) at operation temperatures ranging from -40°C to above 400°C.

Why do sensible heat storage systems require large volumes?

How-ever, in general sensible heat storage requires large volumes because of its low energy density (i.e. three and fi ve times lower than that of PCM and TCS systems, respectively). Furthermore, sensible heat storage systems require proper design to discharge thermal energy at constant temperatures.
