And Oz, I am surprised at you. I specifically mentioned fuel cells,
Again its hopeware. Currently I know of no commercial fuel cell car.
Its expensive, but the Honda FCX clarity is available to customers
"A three-judge international panel praised the Clarity as "an utterly
real, hydrogen-fueled luxury sedan that provides the amenities people
expect in a premium car with [more than 280 miles of] range, fuel
consumption of about 72 mpg equivalent and zero tailpipe emissions." The
cars are being leased to California customers for $600 a month"

That fuel cells are pretty good and tested technology in several areas
doesn't mean they are an instant goer. Also I don't consider these
'electric' in the normal sense, the fuel is after all the same. Well it
might be, but currently (and probably never will be) a matter of filling
up with diesel. Working examples are pretty specific for a pure fuel
(usually methanol) and have limited working lives. It is however a
potential option but is still 'fuel' powered.
I believe there are also two commercial scale farms for production of
algal diesel, open ponds in California and an enclosed system in Holland
Refs please?
Can't you use google? I can't necessarily find the two farms I have
heard of, as there are so many links on the net, but it is easy to find
reports of major oil companies investing in the technology
OK. A set of startups. Not a single real full sized commercial plant.
The links included real full size commercial scale plants. One would
hardly expect them to move into profit in first year of operation.
However it may well happen, even if I prefer solar as a more efficient
use of desert sunlight.
ultimately commercial considerations will determine which technology, or
which mix of technologies, works.
Yes, but better, simpler, cheaper to burn the diesel in internal
combusion engines, surely!
Indeed. Hydrogen, for use in electric cars with fuel cells and algal
diesel for use in internal combustion engines are competing
technologies.
I suspect not hydrogen, better to use a synthetic fuel (eg octane,
methanol) if you really must.
Could be, but most interest of automobile manufacturers seems to be in
H, and one would expect them to have done the sums. A factor is that I
think currently H fuel cells have much longer lives than cells for other
fuels. But in any case once in mass production the fuel cell itself will
not be hugely expensive and will be easily replaced.
