Are Hydrogen Fuel Cells a viable alternative to Gasoline? | |
Every hydrogen fuel cell currently in production or concept uses some form of fossil fuel to generate the hydrogen gas. Are we really saving anything here or are we just covering one problem up with another?
Answers:
1No, hydrogen it's not an alternative to petroleum for producing energy.
The reason is that petroleum is a primary energy source (you don't have to produce it), while hydrogen is an energy vector (to produce it you have to use other primary sources such as petroleum or nuclear).
Of course this doesn't mean that the hydrogen technology is useless. As an energy vector, hydrogen is a good solution to transport energy from one place to another with stricter environmental constraints.
For example, you may produce hydrogen in a big plant far from urban areas, where the pollution can be more efficiently limited, then you use the hydrogen as clean fuel for city cars.
