“Right now, the way we get hydrogen primarily is from reforming gas. That's not an ideal source of hydrogen...The other problem is, if it's for transportation, we don't have a good storage mechanism yet. What else? The fuel cells aren't there yet, and the distribution infrastructure isn't there yet. In order to get significant deployment, you need four significant technological breakthroughs. If you need four miracles, that's unlikely. Saints only need three miracles.” -- Physics nobel prize winner Steven Chu.
