"About four to five kilowatt-hour of electricity would be saved every time a train stops. For a year, the whole station will be able to save up to over half a million kilowatt-hour. It also brings additional impact, such as reducing heat emission. Overall, it works well in terms of energy saving and emission reduction."

A megawatt flywheel storage system was put into use at the Guangyang city station on Beijing Subway's Fangshan line on Monday in China's capital city.
It is the first time the megawatt flywheel storage technology was put into commercial use on a subway system in China, signaling a breakthrough in China's energy-saving technology.
Flywheel energy storage system stores energy in the kinetic energy of fast-spinning flywheels. Different from traditional conventional chemical batteries such as lead-acid battery and lithium battery, it features maintenance free, long service life and pollution free.
When applied to metro subway systems, the technology works to recycle power generated from railcars.
Since speeding trains carry a large amount of kinetic energy, which currently goes to waste when trains slow down to stop at the station. By applying flywheel storage technology, the energy could be stored and converted to electrical power, which in turn would be used to get the train start moving again later.
"About four to five kilowatt-hour of electricity would be saved every time a train stops. For a year, the whole station will be able to save up to over half a million kilowatt-hour. It also brings additional impact, such as reducing heat emission. Overall, it works well in terms of energy saving and emission reduction," said Sun Zhenhai, head of Beijing Subway's Power Supply Branch.
The flywheel systems feature high cycling composite rotors running on magnetic and hydrodynamic bearings at up to 36,000 rpm. The technology, which is in the process of rapid development in China, is expected to be widely used in other fields like high-speed rail, aerospace, medical and power industries in the near future.
"It has already started to solve actual problems and has achieved economic benefits. It has great effect in the field of energy-saving. I believe this technology will spread gradually when it gets more mature. It's of great significance to do so," said Gu Guobiao, an academician of Chinese Academy of Engineering.
