I still think hydrogen is a non-starter. No matter how efficient you get at producing it, the low energy density and near-impossibily of storing it for any significant length of time (it seeps through damn near everything) makes it no match for other fuels.

I second that.

Storage was solved quite a while ago.

"the low energy density"

Depends what you're comparing it to. You're right if you're talking about other hydrocarbon fuels, but H2 has an advantage in energy density (>3000 Wh/l) over Ni/Cd (~400 Wh/l) and even Li/C-CoO2 (~1500 Wh/l) batteries. So if they application is to generate energy for something like a laptop or a video camer, then there might be a market. However, there are some other issues like cost-effectiveness that still make it a tough sell.
