>>>H2 is a pipe dream simply because of lack of infrastructure.<<< I won't disagree. I am intrigued but by no means sold, by H2Gen's concept of rendering hydrogen at the automotive fill up site. There are some interesting intra automotive H2 storage concepts under development. My skepticism arises from what I perceive to be a very low supply of H2 source. NG for automotive use won't last long or be inexpensive. Is anyone familiar with studies comparing the relative efficiencies (capital and energy) of NG through the corn/ethanol path to an automobile's rear axle vice the NG/hydrogen/fuel cell path to same?? I have never seen one, but would love to be informed. I think it obvious that the fuel cell path has the huge advantage of not tearing up crop land and raising prices for everything from tacos to butter. The more I think about it, the more I would think that the fuel cell route would be a slam dunk. Assume (no real analytic basis, just a WAG) that the energy loss going from NG to ammonia/fertilizer is the same as going from NG to H2. H2 is finished at that point. For the ethanol, you have to plant, harvest, distill, blend, store and transport. WRT transport, NG flows over the existing pipe infrastructure. This bears further study. Intriguing.
