Solution to Chicken & Egg Issue with Hydrogen

A Hydrogen-Based Economy

I spent about a month evaluating the economics of using wind power to generate hydrogen. DOE has wind maps showing best areas for reliable wind power.
I don't have the numbers with me but it wasn't hard to show that it takes a lot of wind to generate a single GGE (gallon of gasoline equivalent) of hydrogen. However, considering the vast subsidies we pay for oil (not even counting military and environmental expenses), it seems clear that there is a lot of money to be made.
Regarding the "chicken and egg" problem of "who wants to buy a hydrogen car if there are no hydrogen stations" and "who wants to build hydrogen stations if there are no hydrogen cars", a strategy had occurred to me. Begin the program by providing energy to businesses and cities to run stuff other than cars. There's no reason you couldn't use hydrogen to generate the electricity used in a factory or city water plant. From the brief economic analysis I did it looked feasible to locate fuel cells at the desination (where the electricity is needed) and deliver & store the hydrogen there.
The customer could remain on the power grid to provide backup power in case there was a hydrogen deliver problem (it's new so there will be problems. If they have excess generating capacity there's no reason they couldn't sell power back into the grid.
Using hydrogen in this way would reduce the company's or city's pollution output and might make them eligible for pollution credits (if the US ever decides to join the Kyoto Protocol or something similar).
Selling hydrogen to individual customers with large demand and few & fixed locations would provide a simpler business model as hydrogen production is getting started. As such producers/distributors proliferate, setting up H2-gas stations will be more feasible.
If we don't do it soon in the US then Europe or someone else will do it first and we'll miss out on the economic advantages of controlling market direction.
Perhaps this posting was intended to refer to the newest version of the book? I would suggest that anyone interested in this book either buy it used or wait two weeks for the next edition.
