Another look at fuel-cell cars.
The real problem with hydrogen fuel is not so much the water produced (4.5 pounds for each pound of hydrogen) as it is the carbon. Hydrogen is not a "free" gas--it has to be produced. The most likely methods are electrolysis or production from fossil fuels, such as natural gas or fuel oil. If electrolysis is used, it will most likely be by way of nuclear power plants, which means more of those will have to be built, or by coal-fired plants, which means lots of CO2 will be released. If hydrogen is generated directly from fossil fuels, then the carbon problem remains similar to what we see with burning gasoline, unless some CO2 scrubbers are used.
