The article above is a great read.

^General facts on Fuel-cells
I thought this bit was the most interesting
quote "
A conventional combustion-based power
plant typically generates electricity at
efficiencies of 33 to 35%, while fuel cell
systems can generate electricity at efficiencies
up to 60% (and even higher with
cogeneration).
The gasoline engine in today’s typical car
is less than 20% efficient in converting the
chemical energy in gasoline into power that
moves the vehicle, under normal driving
conditions. Fuel cell vehicles, which use
electric motors, are much more energy
efficient. The fuel cell system can use
60% of the fuel’s energy—corresponding
to more than a 50% reduction in fuel
consumption compared to a conventional
vehicle with a gasoline internal combustion
engine. When using hydrogen produced
from natural gas, fuel cell vehicles are expected
to have well-to-wheels greenhouse
gas emissions less than half that of current
gasoline-powered vehicles.

Came across this article stating that Toyota will start selling hydrogen fuel cell cars in 2015, less then 6 months away. ( http://www.extremetech.com/tag/hydrogen ) and then thought back to that Elon Musk outburst late last year where Elon said Hydrogen cars are bullshit.
I now understand Elons hate, its basically because most of the major car competitors are taking the easy way for EVs in 2015 via fuel cells while he did all the hard work to make EVs cool and popular in the first place with batteries.
While the major car companies make hydrogen-fueling the EV-car "the government and consumers problem", Elon has long attacked it the hard way by putting huge lithium battery packs in the car. His enemies are going to start eating the EV market pie and profits before Tesla makes some of its biggest profit strides yet.
From the article above I found the last paragraph most interesting and shows an interesting future in home made hydrogen.
Or small-scale. At Honda’s R&D campus, I drive the Clarity up to a gate that opens to reveal a prototype of a solar-powered hydrogen fueling station for the home (see picture above). The electrolyzer is powered by a 5-kilowatt photovoltaic panel array and can produce 30 miles’ worth of hydrogen overnight in your garage, from water. (Honda is still working to bring down the cost of home-brew hydrogen.) The gas can also be used to power residential fuel cells like those being developed by power giant NRG Energy.
No utility or oil company needed. Just drivers. (and water)
