An energy storage unit is a device able to store thermal energy with a limited temperature drift. After precooling such unit with a cryocooler it can be used as a temporary cold source if the cryocooler is stopped or as a thermal buffer to attenuate temperature fluctuations due to heat bursts.
For an energy storage technology, the stored energy per unit can usually be assessed by gravimetric or volumetric energy density. The volumetric energy storage density, which is widely used for LAES, is defined as the total power output or stored exergy divided by the required volume of storage parts (i.e., liquid air tank).
The volumetric energy storage density, which is widely used for LAES, is defined as the total power output or stored exergy divided by the required volume of storage parts (i.e., liquid air tank). The higher energy density of an ESS means that it can store more available energy and be more conducive to designing compact devices.
