Power-to-Power

Electricity cannot itself be stored on any scale, but it can be converted to other forms of energy which can be stored and later reconverted to electricity on demand, reducing imbalances between energy demand and production. Energy, however, comes in multiple forms including radiation, chemical potential, gravitational potential, electrical potential, electricity, elevated temperature, latent heat, and acceleration. Storage systems for electricity include battery, flywheel, compressed air, and pumped hydro storage.
