Germany has rolled out the world’s first hydrogen-powered train built by French company Alstom.
Hydrogen trains are equipped with fuel cells that produce electricity by combining hydrogen with oxygen, a process that leaves steam and water as the only emissions.
This makes the cells a promising energy source that produces zero emissions and very little noise. Excess energy is stored in ion-lithium batteries on board the train.
The locomotives are also eco-friendly. The only disadvantage is that they are more expensive than the fossil fuel-based trains, but are cheaper to run.
