    On One Hand: Hydrogen Cars Do Work

    A number of major automobile manufacturers have tested hydrogen fuel cell technology. There are some limited real-world tests going on in selected markets. Hydrogen-powered cars emit zero hydrocarbons, only water vapor. The fuel cells are used to generate electricity, which powers electric motors that replace a standard gasoline engine.

    On the Other: There are Problems

    Hydrogen fuel cells are expensive to produce; they cost between $1,000 and $3,000 per kilowatt to produce. One popular hybrid car has a 70-kilowatt motor. An all-electric sports car has a 215-kilowatt motor; that makes building the vehicles very expensive.

    Bottom Line

    Hydrogen works in cars, but it isn't very practical. There currently isn't a wide-spread fueling network for hydrogen vehicles, so even if you could build a car at a cost-effective price, you couldn't drive it very far because there aren't enough fueling stations.
