The present research examines the possibility of using conventional steel springs as a form of grid-scale mechanical energy storage.
Small increments of low force energy are applied to an hydraulic pump which drives an hydraulic motor which energy is converted to a torsional force in a spring.
A flywheel is a device that stores energy in a spinning mass. Flywheels are used, in addition to batteries, in some electric and hybrid vehicles
Because this type of spring is a non-standard product, the same shape has different sizes.

The concept of using a torsion spring as a means of mechanical energy storage before the energy conversion to electricity has the substantial benefit of being able to directly capture and accumulate all input motion, even in the event of sudden impacts, and then convert this mechanical energy through a motor to provide a smoothed electrical output.
The centre of the Torsion Spring is connected directly to the output from the MRR via a bolt threaded into the Output Shaft. This means that the spring is able to wind up from the inside to mechanically store the kinetic energy provided by the pendulum via the MRR.
Energy storage can be provided by using a conventional motor and power electronics circuits. This method is generally used in large flywheel energy storage systems (heavy mass). In this method the rotation speed of the rotating object is not high . Energy storage is performed by radius and weight parameters in this method.
In this storage scheme, kinetic energy is stored by spinning a disk or rotor about its axis. Amount of energy stored in disk or rotor is directly proportional to the square of the wheel speed and rotor׳s mass moment of inertia.
