Outline of energy storage
The following outline is provided as an overview of and topical guide to energy storage:
Energy storage – accomplished by devices or physical media that store some form of energy to perform some useful operation at a later time. A device that stores energy is sometimes called an accumulator.

General energy storage concepts
1. Using a high density magnetic field. Energy 
in terms of magnetic field strength 
is
where 
is the inductance of the electromagnet and 
is the current.
