Electric car-makers like Tesla, are constructing mega factories for mass production of Li-ion batteries to reduce the price of cars. On other hand Japanese companies are investing heavily on hydrogen Fuel cell technology. This race is not about who will come first, rather who will sustain in global market finally. Presently and decisively Electric vehicle driven by Li-ion batteries are leading the trend with reduction in battery pack price and increase use of solar energy. Electric vehicles made lot of improvement in recent time. Much of it can be attributed to Tesla-first electric car-maker who took concept of electric cars much seriously than any other car-maker. They set very high standard for electric cars and make much needed improvement to compete with traditional IC engine cars running on gasoline. Charging time reduced from hours to several minutes. Mileage too increased considerably. All these improvement made Electric Vehicle ( EV) a better solution to IC engine causing pollution. EV do not cause air or sound pollution and they are safe car. However, they need electricity to charge batteries. Sometimes electricity is produced by burning coal, which again cause pollution. Solar power is a workable solution. However, with present efficiency of solar cell, it will be difficult to fulfill future domestic demand. Thus, electric vehicles are not the best solution for future in developing countries where managing domestic electricity demand is a challenge.
In future, people will prefer car with inbuilt energy powerhouse. A car, which can run longer than normal electric vehicle and IC engine without creating pollution and have a safe quick re-filling. As soon as hydrogen or any other fuel cell meet these criteria then that will be the turning point in history of Fuel cell vehicle (FCV). At present, peoples are concern about safety of using hydrogen as fuel. Of course, electric vehicle are safest compared to FC and IC engine. Nevertheless, with advancement in technology, fuel cell will become safer than IC engine, which we used for decades. The biggest obstacle for fuel cell cars is filling station, which require lot of money in establishment. Without filling stations, no one will buy such cars. Slowly but surely as filling station will increase, demand for FCV will increase too. With improvement in technology and mass production, price of cars fitted with Fuel cell will decrease considerably.
As we have saying, “Slow and steady wins the race” it is possible that future belongs to Fuel cell Vehicle. Batteries are temporary solution. If we find a way to fill a vehicle directly from hydrogen cylinders then we can cut off expansive filling station requirement too.Normally a FCV requires 35-90 MPA pressure. In market, cylinders are available up to 90MPa as well. We only need a hose pipe with connector to fill the Car tank. Some innovative ideas required to make FCT a feasible reality. Japan is investing hugely to make improvement in fuel cell. Only future will tell which technology will pass the test of time.
