For energy storage, the energy density relates the stored energy to the volume of the storage equipment, e.g. the fuel tank. The higher the energy density of the fuel, the more energy may be stored or transported for the same amount of volume. The energy of a fuel per unit mass is called its specific energy.
Storage energy density is the energy accumulated per unit volume or mass, and power density is the energy transfer rate per unit volume or mass.

High energy storage density means that more electric power can be stored in dielectrics per unit volume. Dielectrics are broadly classified into linear and nonlinear dielectrics based on the relationship between electric displacement (D) and applied electric field (E) .
Energy density differs from energy conversion efficiency (net output per input) or embodied energy (the energy output costs to provide, as harvesting, refining, distributing, and dealing with pollution all use energy). Large scale, intensive energy use impacts and is impacted by climate, waste storage, and environmental consequences.
Generally, the stored energy density (Ue) of a dielectric is the integration in the shadow region as illustrated schematically in Fig. 6.17. The permittivity and electric breakdown strength are the two key parameters influencing the stored energy density. Much effort has been paid to improve the energy storage performance.
The volumetric energy storage density is the amount of heat that can be released per volume unit of either the sorbent material (hereafter marked Qmat) or the whole system (Q sys, i.e. including the reactor and all the components for the management of air flow, in atmospheric systems, or of vapour and heat transfer fluids, in pressurized systems).
