Isn't the by product of burning hydrogen, water?
This can also end droughts, just imagine how much water would be in SoCal if 15 million people are driving these cars and all the moisture it would produce??? Dunno, just a thought.

From the article:
"Dave Barthmuss, a GM spokesman, said that automakers consider cars powered by hydrogen fuel cells their "Holy Grail," since they would release only water as emissions and could end America's dependence on foreign oil."
Not until we figure out how to make very large quantities of hydrogen from something other than current fossil fuels as it is now. And as far as pollution reduction, currently, all we would accomplish is to move the pollution to the hydrogen production facility unless someone invents a process to inexpensively sequester the carbon during production.

All that extra water vapor will cause Global Warming.
"All that extra water vapor will cause Global Warming."
Can't we blame Bush for that, too?

No offense to you, I'm sure you're just mocking the typical unpleasable tree hugger nitpicking, but people overlook the fact that gas engines emit water too...
Water and a whole lot of other "stuff"
Until we all ride bikes, (or better yet, walk) transportation will make pollution.
The goal is to find that which makes the least pollution while conserving non-renewable resources.
Has there been any progress made on producing large quantities hydrogen by electrolysis, breaking water into its component hydrogen and oxygen? I caught a glimpse of an article about electrolysis for oxygen production that considers hydrogen an unwanted by-product. Seems to me that ‘unwanted by-product’ is actually quite valuable.
I found a link to a lot of links about hydrogen production. EERE Information Center
There is a lot of information here.
I hate to see tax money being blown on hydrogen boondoggles.
What seems to be lacking in any of the Mary Poppins hydrogen news releases is any reference to a solid analysis of what it would take to make a hydrogen fueled system work in the real world. I don't expect to see that analysis in the forseable future.
About 4.3kWhr for 1 cubic metre of hydrogen gas.
16MJ in, 10MJ out.
Now consider that the electricity is generated at 40% efficiency, and the hydrogen is burned at 30%, or maybe 60% in a fuel cell.
Not to mention that it's a very slippery gas, so transport losses will be considerable.
I'd like hydrogen to be part of the answer, and it is a part......not the whole answer.

If a hydrogen system were to be developed, the only reasonable way to produce the hydrogen is by electrolysis of water.
That requires a lot more electricity than we produce today and more infrastructure )power lines, power stations...) to generate and transmit the power.
The electricity can come from multiple sources. That's one of the beautys of electrical power. You can generate it many ways. For now we could use all present power sources to generate electricty. Then more nuclear and more photovoltaic. Maybe thermonuclear some day.
New hydrogen filling stations for cars would be needed. Their primary inputs would be electrical power and water. Lots of electrical power and not real big amount of water. Roughly the same quantity of water that a gas station moves in gasoline each day.
If you know how many gallons of gasoline a big gas station pumps today, it's simple to calculate how much electrical power it would take to produce an equivilant amount of hydrogen. Without going out on a limb, one could confidently say it would be metric sh*tload of electrical power.
