The energy storage density (ESD) refers to the energy stored per unit mass of the flywheel. According to Eqs. (1), (4), and (5), the energy storage density can be obtained as: From Eq. (6), it can be seen that increasing the effective turning radius R of the flywheel and the speed can increase the energy storage density.
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.
Energy density is the amount of energy stored in a given system or region of space per unit volume or mass, though the latter is more accurately termed specific energy. Often only the useful or extractable energy is measured, which is to say that chemically inaccessible energy such as rest mass energy is ignored.
Among them, LiCl/H 2O, with the best energy storage density (1219 Wh/kg), needs lower temperature, which is only 66 °C. Chemical reactions present high heat storage capacity in a wide range of temperature. KOH, LiBr, MIL-101, NH4 Cl/NH 3, NaOH (s), NaBr/NH 3 and BaCl 2 /NH 3 all show the prospect of application in SSLTHS.
In cosmological and other general relativistic contexts, however, the energy densities considered are those that correspond to the elements of the stress –energy tensor and therefore do include mass energy as well as energy densities associated with the pressures described in the next paragraph.
