Like you, I'm all for improving Hydrogen technology. I still don't understand why we aren't cracking H2 out of the excess methane that is currently "flared" off of the remote NG pump sites. I'm not certain the exact process, but in places like West Texas it sure seems like we could park a windmill next to it to provide the power, eliminating the need for extending the power grid all the way out there, or even running a pipeline although you'd have to transport the H2 eventually.
The real problem I see with H2 is its energy density. It's nowhere near that of fossil fuels, so the physics says you'll need more H2 to equal the same energy of oil/gas/coal/whatever, regardless of how you convert it to electricity. I'm sure there are good applications for Hydrogen Fuel Cells and we should pursue them, but cars ain't one of them.
