The ability to mass produce hydrogen-powered vehicles and fuel needed to run them has been available for many years, however, experts industry still believe that technology is 10 to 20 years away from being a conventional fuel supply. This is not due to lack of experience of manufacturers in the production of hydrogen fuel cells, or vehicles that run on them.
The first hydrogen fuel cell vehicles was built in 1960 powered by General Motors in the United States. Hydrogen fuel cells are also used in space by NASA in the 1960s. Given account of the impressive pedigree and early development of the fuel, why is not yet a commercial reality?
The facts are that hydrogen is a very dangerous substance, and these dangers are present not only the end consumers, but all the way through the production, transport and storage. A tank of pressurized hydrogen in many respects, like a time bomb. Any damage to the structure of the vessel containing the hydrogen could lead to an explosion powerful, even relatively small tank, like those to be installed in cars.
There is also the question of using electricity to produce hydrogen in the first place. This in itself is quite energy intensive and involves energy losses at each stage of processing from one form to another, such as when electrical energy is converted into chemical energy to form hydrogen molecules. Even if the electricity is generated from clean sources such as solar panels could be used directly to charge batteries or supply a network with greater efficiency than for hydrogen production.
So what is the future of the fuel cell? Fuel cells have to run only on hydrogen. It can run on many fuels different, including methanol and ethanol. Both these substances can produce electricity at a much lower cost than hydrogen. These fuels do not produce dioxide emissions however carbon, although this could be neutralized by the use of biofuel crops to produce fuel in the first place.
A Unless we can produce almost unlimited amounts of energy from the hydrogen economy is unlikely to arise. Our time would be better spent discussing the current battery of electrical systems.
