Storage principles. Electrochemical capacitors use the double-layer effect to store electric energy; however, this double-layer has no conventional solid dielectric to separate the charges. There are two storage principles in the electric double-layer of the electrodes that contribute to the total capacitance of an electrochemical capacitor:
A flywheel system stores energy mechanically in the form of kinetic energy by spinning a mass at high speed. Electrical inputs spin the flywheel rotor and keep it spinning until called upon to release the stored energy. The amount of energy available and its duration is controlled by the mass and speed of the flywheel.

Power systems in the future are expected to be characterized by an increasing penetration of renewable energy sources systems. To achieve the ambitious goals of the "clean energy transition", energy storage is a key factor, needed in power system design and operation as well as power-to-heat, allowing more flexibility linking the power networks and the
The majority of storage techniques therefore come under four broad categories: mechanical energy storage, chemical energy stockpiling, electrochemical energy stockpiling, and electric energy storage. The maximum amount of electrical work that can be extracted from a storage system is given by, (1.1) G = H − T S.
For single dielectric materials, it appears to exist a trade-off between dielectric permittivity and breakdown strength, polymers with high E b and ceramics with high ε r are the two extremes [15]. Fig. 1 b illustrates the dielectric constant, breakdown strength, and energy density of various dielectric materials such as pristine polymers,
