A review of technologies and applications on versatile energy storage

According to statistics from IEA [2, 3], the total energy supply (TES) in 2018 is about 14279 Mtoe, and the total renewable energy, e.g., biomass fuel, hydrogen energy, solar energy, and wind energy is about 2682.7 Mtoe, which accounts for 18.78% of the total amount.

Energy density

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. The adjacent figure shows the
