The world’s first hybrid electric tram powered by hydrogen fuel cells started in China

The world’s first hybrid electric tram powered by hydrogen fuel cells has started running in China to give big boost to green energy in public transport. The tram was put into commercial operation for the first time in Tangshan, north China’s Hebei Province.
With water being its only emission, the tram emits no pollutants. No nitrogen oxides will be produced as the temperature of the reaction inside hydrogen fuel cells is controlled under 100 degrees Celsius. The tram, having three carriages with 66 seats, can run for 40 kilometers at a maximum speed of 70 kilometers per hour after being refilled with 12 kilograms of hydrogen.
