Correspondingly, is hydrogen a viable fuel alternative?
One hope for our energy future lies in hydrogen -- an infinitely renewable and relatively pollution-free fuel that scientists and politicians alike see as a viable alternative to fossil fuels. And if that wasn't enough, hydrogen fuel is about three times more efficient than gasoline [source: US News].
Also Know, what are alternative fuels an alternative to? Some well-known alternative fuels include bio-diesel, bio-alcohol (methanol, ethanol, butane), refuse-derived fuel, chemically stored electricity (batteries and fuel cells), hydrogen, non-fossil methane, non-fossil natural gas, vegetable oil, propane and other biomass sources.
Keeping this in view, why is hydrogen not used as fuel?
Although hydrogen has the highest calorific value, it is not used as a domestic fuel. It is because hydrogen is a highly combustible and it reacts explosively when it comes in contact with air. So, even though hydrogen has the highest calorific value, it is not used as a domestic fuel.
Why is hydrogen fuel better for the environment than gasoline?
Hydrogen fuel cells have been widely touted as an environmentally-friendly alternative to conventional fossil fuels. By oxidising molecular hydrogen, the only direct by-product of their energy generation is water, which means they could significantly reduce pollution and man-made greenhouse gases.
