HYDROGEN AS A FUEL 

 A good fuel has a high calorific value, should be environmentally safe, should leave no harmful residue after burning, should be easily accessible & last but not the least, should be easy to store and transport. Hydrogen acquires all these qualities & hence, playing a trump card over fossil fuels. Hydrogen can be used as an excellent fuel in automobile industry too. Many cars from leading brands like Hyundai Nexo, Toyota Mirai, Honda Clarity, etc. are still using hydrogen as a fuel. But hydrogen as a fuel as its own loopholes too. Almost all countries have no proper hydrogen refueling stations and do not have plans to develop these too, therefore making its use impractical. Also, it is not so economical as it is very expensive. Also, safety is a major concern in hydrogen-powered cars because in case of severe collision, hydrogen, a highly flammable gas, may leak and explode. Many cars like Hyundai Mirai have tried to limit these drawbacks as much as possible by incorporating a highly strengthened fuel tank and many other sensors to detect fuel leakage. Still, it seems that in far future, hydrogen would be one of the best choices for fuel. But now, it is the era of fossil fuel cars and electric cars which have built a great market in the whole world and hydrogen has still a long journey through to compete these.
