Fuel Cell Locomotive

I don't see how a fuel cell locomotive would save anything in fuel costs. The hydrogen required by the fuel cells is much more expensive to buy, store and transfer than diesel. Even figuring the efficiency difference and the idling losses, hydrogen is expensive, very clean at the final user, but expensive. <br /> <br />That is another thing that bothers me about the proponents of fuel cells. The statement that the hydrogen is "clean burning" and produces no "greenhouse gasses". While that statement is true as far as it goes, where does the hydrogen come from. There are no hydrogen wells or mines. It must be manufactured from oil, coal or electrically separated water. And in doing so Carbon Dioxide is released, in great quantities. That is of course unless you are using a nuke power plant, and that comes with another whole set of problems.
