Currently hydrogen is produced using electricity, over 80% of which is
generated by burning fossil fuels - therefore generating lots of CO2.

Honda say:

"CO2 emissions related to the production of hydrogen vary by source;
however, well-to-wheel CO2 emissions using hydrogen reformed from natural
gas - the most widely used method of production today - are less than
half that of a conventional petrol vehicle. With the production of hydrogen
from water by electrolysis, CO2 emissions can be further reduced and
ultimately approach zero if the electricity is generated from sustainable
sources, such as solar, wind, hydro and wave power."

which sounds fantastic - but then it would from them wouldn't it

Interesting they don't mention nuclear as an option...

The 5,000-psi hydrogen storage tank is slightly scary as well - but then
everyone driving around with a plastic tank containing 10 gallons of
petrol is scary I guess..

It is difficult to think of anything more pointless at this time than a
hydrogen fuel cell powered car. That will change when we have a lot
more power generated by nuclear and renewables. But that won't be for
at least another 15 years.

I can't really see prius type hybrids making massive gains either. I know
two people who bought a prius. Neither have them now :-)
