Energy density is the key technical criterion for energy storage. The energy density consists of both the energy stored per unit mass or per unit volume of the energy storage medium. Carbon-based chemicals are very high in both areas.
To improve energy storage energy density, hybrid systems using flywheels and batteries can also be attractive options in which flywheels, with their high power densities, can cope well with the fluctuating power consumption and the batteries, with their high energy densities, serve as the main source of energy for propulsion .
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).
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.
