Mechanical Electricity Storage

How Flywheel Energy Storage Systems Work. The high surface area of the water droplets coupled with the high heat capacity of water relative to air means that the temperature stays approximately constant within the piston – the water is removed and either discarded or stored and the cycle repeats. A similar process occurs during expansion.

Could Flywheels Be the Future of Energy Storage?

These systems work by having the electric motor accelerate the rotor to high speeds, effectively converting the original electrical energy into a stored form of rotational energy (i.e., angular momentum). The flywheel continues to store energy as long as it continues to spin; in this way, flywheel energy storage systems act as mechanical energy

Flywheels are not as adversely affected by temperature changes, can operate at a much wider temperature range, and are not subject to many of the common failures of chemical rechargeable batteries. They are also less potentially damaging to the environment, being largely made of inert or benign materials. Another advantage of flywheels is that by a simple measurement of the rotation speed it is possible to know the exact amount of energy stored.
