I don't know much about hydrogen technology, but it strikes me as strange that there would be a push toward something so unsustainable... although then again, I live near the ethanol capital of the world, which is very proud of that title. |
Its hard to explain, really, but basically its because hydrogen isnt a source of energy, it's an energy carrier. So you have to produce the energy and then process it into the hydrogen. Here is a slide to help illustrate. See how you have to get the initial energy from another source?
