Compressed Gas
Compressed gas is another way to obtain mechanical energy storage. When a piston is used to compress a gas, energy is stored in the gas and can be released later by reversing the movement of the piston. Pressurised gas is therefore an energy store. It can release energy which can be used to perform useful work.
