Flywheel energy storage
Flywheel energy storage (FES) works by accelerating a rotor to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy ; adding energy to the system correspondingly results in an

The future of energy storage: are batteries the answer?
And, when it comes to storing energy using batteries, the electric car has a role to play. There are two ways that the batteries from an electric car can be used in energy storage. Firstly, through a vehicle-to-grid (V2G) system, where electric vehicles can be used as energy storage batteries, saving up energy to send back into the grid at peak times.

Why is electrical energy so difficult to store?
2. A general answer which is not of any particular use is that electrical energy, and the forms in which we store it, are typically very low entropy systems. The lower the entropy the more they "want" to dissipate and the harder it is to stop that tendency to turn into (ultimately) heat.
Lift Energy Storage Technology: A solution for decentralized urban energy
This paper proposes using lifts and empty apartments in tall buildings to store energy. Lift Energy Storage Technology (LEST) is a gravitational-based storage solution. Energy is stored by lifting wet sand containers or other high-density materials, transported remotely in and out of the lift with autonomous trailer devices.
