Correct me if I’m wrong, but, don’t these so-called hydrogen cars put out water vapor? Granted, it will be at a much lower level of the atmosphere, but, wouldn’t more water vapor in the air cause worse climate issues?
Expelled water at lower heights does not last very long in the atmosphere. I am most concerned with the refilling sites. These would not be good things around earthquake zones, or having lay people do the refilling, or as terrorism targets. But I guess they could be overcome, but a regulatory and safety nightmare.
Well, they could say the same for regular gasoline stations and refineries. I, for one, am for exploring the feasibility hydrogen powered vehicles on a national or global scale. As you stated, there would necessarily have to be many considerations before we could embrace it, but the tech has been there for several years now, its time to either forward it, identify the logistical problems, or scrap it.
Maybe we could start mining H2? I hear they have large deposits in the country where Obama was born.
Well, yes, Kenya has vast reserves, but they’re not the light sweet H2 found in places like California,
where mammalian brains are full of the stuff.
Can’t use H2. That what blew the tops off the Japanese reactor buildings. Things that go boom are not allowed.
What is the cost (both in terms of dollars and energy/CO2) in producing Hydrogen? After all it does not exactly grow on trees.
I am sure though that if it is economic it will not be long before production begins big time.
How to produce hydrogen in very easy steps using fossil fuels 🙂

remember when the liberals were all going to put the oil companies out of business by turning food to fuel…
This will not set well when they realize they are still having to pull up to the pumps
What’s the cheapest way to make H2? Steam reforming of natural gas of course. So if you make a hydrogen car, it will most likely be powered by processed natural gas. (Or you could just make a car that runs on natural gas directly.)
The big problem is in the energy needed to separate hydrogen from water. “Things that go Boom” are things where energy is released. You have to put that energy back in to make some more boomy things. The technology exists…hydrolysis…which uses electricity to [slowly] separate the hydrogen from oxygen. It’ll take massive amounts to keep up to a freeway full of hydrogen-guzzlers.
It is the future but it is not well known.

Latitude, why is it crazy to feed our food to cars? answer: Because we cannot eat petroleum.
