Saving energy using flywheels
The flywheel system has shown through experimental testing to greatly reduce the fuel consumption and emissions output. In addition, the reduced peak power demand from the diesel engine increases the engine life. Furthermore, because of the energy storage made available by the flywheels, the diesel engine can be reduced in …
Flywheel Energy Storage System Basics
The kinetic energy of a high-speed flywheel takes advantage of the physics involved resulting in exponential amounts of stored energy for increases in the flywheel rotational speed. Kinetic energy is the energy of motion as quantified by the amount of work an object can do as a result of its motion, expressed by the formula: …

Analysis of a flywheel energy storage system for light rail transit
Results suggest that maximum energy savings of 31% can be achieved using a flywheel energy storage systems with an energy and power capacity of 2.9 kWh and 725 kW respectively. Cost savings of 11% can be obtained by utilizing different flywheel energy storage systems with 1.2 kWh and 360 kW.
Flywheels: A Power Protection Alternative
Acting as a mechanical battery, the flywheel stores kinetic energy in a high-speed rotating group and converts it back into electrical energy to support critical loads. Providing ride-through time to bridge power to the backup generators, the flywheel system is a space saving, near-zero maintenance, and affordable means of guaranteeing …
