- Hydrogen trains are equipped with fuel cells that produce electricity by combining hydrogen with oxygen.
- This conversion process only emits steam and water, thus producing zero emissions.
- Excess energy produced is stored in ion-lithium batteries on board train.
- These trains also make very little noise. Moreover, hydrogen fuel cells have advantages over batteries.
- Instead of recharging, they can easily be refueled like gas or diesel engine.
- It is also easier to build refueling infrastructure for these trains at railway stations.
- These trains can run for around 1,000 km on a single tank of hydrogen, similar to the range of diesel trains.
- These trains offer attractive prospect to many cities scrambling to combat air pollution.
- The only disadvantage these hydrogen trains is that they are more expensive than fossil fuel-based trains.
