RAIL & TRANSIT APPLICATIONS

Trains and rail vehicles brake using motors or some combination with brakes, creating heat and contributing to equipment operation problems, degradation, passenger comfort, and heat strain risk. The kinetic energy of the train is dissipated through large electrical resistors or friction brakes thereby wasting the braking energy as heat. Expelling this unwanted heat presents cost, energy and technical challenges. Because trains are heavy and moving at high speed, the amount of energy lost on every braking event is significant.

Our flywheel energy storage system can adjust and effectively absorb the energy generated by the train brake and store it, and release the energy required by the train when the train accelerates. At the same time, it can replace traction substations, stabilize the rail grid voltage, improve the quality of the rail grid, and significantly reduce the substation deployment costs.
