If my memory serves me correctly, I believe that the current infrastructure (meaning pipelines) can easily carry hydrogen. In fact they often use the same pipeline for many different types of fuels. One interesting thing to note is that all gasoline companies get their gas from the same sources and pipelines. It is also standard practice for, say, BP to place an order to a refinery for X gallons, and then immediately "retrieve" whatever comes out of the pipeline, even though the trip through the line takes several days. Also keep in mind how dangerous gasoline is now.
I suspect W has alterior motives. To me his speech sounded more like a campaign speech. He is telling us what he thinks we want to hear. Don't believe it until it happens. For example, while Bush is trying to look environmentally friendly, he has been the torch-bearer for the Yucca Mountain project, in which all the nation's nuclear waste goes to the site in Nevada, which is in a notorious earthquake area, in a volcano.
It's the easiest way out although safer solutions have been proposed. In my opinion, I truly think that nuclear power is the biggest mistake we have ever made. All Nuclear Power plants should be closed. We have proved that we can clean up air pollution; cleaning up nuclear waste is impossible. It will be there for millions of years.
Today, on my way to school, I got into a traffic jam because of two trucks carrying very large containers (so large the trucks took up 2 lanes). I was turning off the highway they were on, and as I passed them, I saw cute little signs on the containers, saying "RADIOACTIVE" and having the little atomic symbol on them. Great. So what happens when Yuccan Mountain opens for business?
"Waste shipments would be so frequent that Atlanta, Cleveland and San Bernardino would see shipments traveling through their neighborhoods on a daily basis. Chicago would see one shipment every 15 hours; St. Louis, Kansas City and Denver, every 13 hours; Des Moines and Omaha, every 10 hours; Salt Lake City, one shipment every seven hours. "
"According to one DOE estimate, there will be as many as 310 accidents in the course of transporting this highly radioactive waste across the country."
The waste containers cannot be designed so as to not leak, and they are expected to emit the equivilant radiation in one hour of one chest x-ray.
"In gridlock, however, a person sitting in a car next to a cask containing nuclear waste could get a radiation dose equal to that of four chest X-rays if the traffic jam lasted long enough."

Comments on the terrorism issue: Do you really know what was happening in the years and months leading up to 9-11-2001?
"President Clinton ordered two attack submarines to stand watch over the Taliban and bin Laden's terrorists. Bush ordered the subs to stand down. [See: The Covert Hunt for bin Laden: Broad Effort Launched After '98 Attacks, The Washington Post: 12/19/01.
http://www.washingtonpost.com/ac2/w...ode=&contentId=A62725-2001Dec18¬Found=true] Clinton warned the Taliban he would hold the Taliban leadership personally responsible for any attack by bin Laden against Americans. Bush lifted that decree. [See: Clinton's War on Terror: The Covert Hunt for bin Laden, The Washington Post, 12/20/01.
http://www.washingtonpost.com/ac2/wp-dyn/A62776-2001Dec18?] But Bush eliminated these safeguards."
"Greg Palast reports Bush ordered national security agents to "back off" the bin Laden terrorists. "
"Bush sent $43 Million to the Taliban. His administration supported negotiations with terrorists on behalf of his campaign contributors. These included corporations seeking to build a pipeline [pipeline...now how could you not believe that!] through Afghanistan."
