Search for clean fuel for automobile took us to two different directions: one towards Electric vehicle which uses lithium-ion batteries and charging ports and another is hydrogen cell which use hydrogen from filling station. Both are clean solution. Electric vehicle has no effluents and Hydrogen cell cars produce water. But the most important difference is that for electric vehicle we have to first produce electricity using other sources, some of them may not be renewable like coal and thus still cause pollution. So basically we are just shifting problem from one place to another. In developing countries where we do not have enough electricity for 24 hours supply in cities forgets about villages, adding more consumption will be disaster. If electricity will be cheaper than petrol (which seems likely in few years) when use in automobiles, for economic reason people’s will buy electric vehicles. Electric cars are far better than combustion engine cars and have less maintenance. Thus there will be huge increase in demand of electricity in future. Big question is how we will manage the increasing demand of electricity when we are already short of supply?
Hydrogen fuel cell is the solution. Already many countries started using hydrogen fuel cell. It is a proven technology. Instead of electric charging station we have to build hydrogen charging station. No more infrastructures required! No burden on electricity production. No need of batteries. Japan is producing and paving the way for hydrogen cell vehicle. Japan, Germany and US are increasing hydrogen filing station. UAE also opened its first hydrogen filling station. Though this technology is expensive but is the real solution of pollution. With tie and more and more use of this technology it will become cheaper and better.
