Are fuel cell vehicles in our future? Our near future?

ETA: Short answer, Not Our Near Future. Build up that charging infrastructure, because that will still be in demand when children yet unborn are chomping at the bit to get their driver's license. And maybe for a while after that.

The Prime Minister got to drive the Toyota FCV.

Fuel cells made it very tough to get hybrids and BEVs going earlier, because there was sort of this idea that battery tech was sort of awful and the range was horrible, and fuel cells were Right Around the Corner so why waste time on this shit? Naturally, this makes me suspicious of fuel cells at this point, since GM (and, for that matter, Ford) who were so negative on anything between ICE and fuel cells wound up abandoning fuel cells in favor of that interstitial generation they were so contemptuous of.

R. seems to think there's a power to weight issue with fuel cells. I, of course, am prepared to be picky about where the hydrogen comes from. Still working on the power to weight issue, but I am skeptical that there is an issue here.

A bit more in detail: http://www.caranddriver.com/news/toyota-fcv-concept-news

Honda has some competition that might be better, altho not as far along in terms of production:

Is this why they are retiring the Fit EV and the aging Insight? Or is this just a round of the Japanese making the same mistakes GM and Ford did a decade ago?

It looks like R. is correct in thinking that fuel cells require a ton of space in the car for all the stuff to Make It Go. There is no range problem (altho a fueling infrastructure is needed). I cannot even imagine parking some of these things, and of course there's just no room to bring anything bigger than your purse with you.

This explicitly asserts that R. is wrong about the energy density issue:

And this guy is really not a believer:

This isn't very encouraging:

Where's the make-hydrogen-from-water-using-solar-panels option? Maybe that's so inefficient it is pointless?

Oh, wait, here it is!!!

http://world.honda.com/news/2012/4120327Solar-Hydrogen-Station/index.html

Oh, geez:

"Using Solar and grid power, the system is capable of producing 1.5kg of hydrogen within 24 hours which enables an FCX Clarity to run approximately 150km or 90 miles."

Ooooh, that's not good enough. 24 hours to get 90 miles of range. Ouch. Ouch. Ouch. And with zero cargo space and limited passenger space in the vehicle.
