World needs more energy than ever and also addressing the co2 emission that impact on environment .so we need to shift to sustainable energy that meet the future requirement from pollution free society with cost efficient.
Although hydrogen powered technology is still infancy is some countries still believing that this technology is used in limited basis, but India accepting this technology is early sign of developing countries with initiative of adopting green technology.
OVERVIEW OF THE TECHNOLOGY:
WHY HYDROGEN:
Hydrogen is easy and basic element with light weight than helium found in the atmosphere that each molecule of water has 2 atom water for every hydrogen atom. It can be separate from several process like electrolysis process and steam reforming etc.
Working: Technology of hydrogen propulsion system is the fuel cell. In this process convert chemical energy within hydrogen in order to generate electricity as well as water and heat. The electricity is produced by infused hydrogen in the electric generate motor. The efficiency of converting electricity to hydrogen and back again is just 30% roughly similar to contemporary diesel engine but less than conventional diesel engine.

There is zero emission of carbon-di-oxide in this process with 3times cost efficient than internal combustion engine. They can run on the existing rail infrastructure without addition electricification.it can run long range of up to 1000km at speed of 140k/hour between refueling. It is 10times farther than battery .it has long asset life compared to electrification.it provide smooth driving experience and low noise level with exhaust of water

CONCUSION:
Hydrogen fuel cell are promising alternative to current automobile fuels. They essentially combine the energy density and convenience of liquid fuel with clean and efficient operation of electric vehicle. Although certain aspect of technology still require some improvement there is no reason why hydrogen could not become equally convenient attraction transportation fuel than diesel.
