Mechanical Energy Storage systems store energy by converting it into different forms such as kinetic or potential energy, providing grid stability and backup power. These systems operate on the principle of storing energy in the form of mechanical motion or elevation, which can be later converted back into electrical energy when needed.
How do flywheels store energy?
Here a flywheel (right) is being used to store electricity produced by a solar panel. The electricity from the panel drives an electric motor/generator that spins the flywheel up to speed. When the electricity is needed, the flywheel drives the generator and produces electricity again.
Forms of energy
Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy. For example, chemical energy is converted to thermal energy when people burn wood in a fireplace or burn gasoline in a car''s engine. Mechanical energy is energy stored in objects by tension.

Types of energy (article) | Khan Academy
Thermal energy is energy in disorderly motion - everything is moving in random directions. When people talk about "kinetic energy", they usually mean energy in orderly motion - everything moving in the same direction. The meaning of "orderly" can be a bit subjective, usually depending on how closely you''re looking at the particles.
