How do mechanical energy storage systems work?

Mechanical energy storage systems take advantage of kinetic or gravitational forces to store inputted energy. While the physics of mechanical systems are often quite simple (e.g. spin a flywheel or lift weights up a hill), the technologies that enable the efficient and effective use of these forces are particularly advanced.

How does rotation store energy in a flywheel?

The principle of rotating mass causes energy to store in a flywheel by converting electrical energy into mechanical energy in the form of rotational kinetic energy. The energy fed to an FESS is mostly dragged from an electrical energy source, which may or may not be connected to the grid.
