10 Main Types of Energy Storage Methods in 2023

Flywheel Energy Storage. Flywheel energy storage devices turn electricity into kinetic energy in the form of spinning wheels, which can then be used to store grid energy. To avoid energy loss, the wheels are kept in a frictionless vacuum by a magnetic field, and the spinning can be reduced in a way that creates electricity when power is required.
