The CO and H2 is coming from gassification of biomass.

How much energy does it cost to gasify biomass? How much does the
biomass cost to produce? I seem to recall a plan to produce oil from
"useless" turkey carcasses... Then once the supplier found out they
weren't "useless", the costs went up drastically.

About 15% with world war II technology.


The CO is "reformed" into more H2 using petrochemical terminolgy.

Producing the H2 on board is better than conventional batteries because
you can fill a tank with fuel drive 500 miles and refil the tank as
needed. Conventional batteries are expensive, low capacity, slow to
recharge and have a limitted life.

How fast do you think you can convert biomass to H2 and CO? Can I get a
couple kilo's and drive away immediately?
So how much cheaper are these fuel cells? What is their duty cycle? Do
the safety issues around hydrogen outweigh other solutions?

Once the fire is lit you can produce enough H2 and CO to run a farm tractor
plowing a field, or run a full sized city bus. I have seen pictures of
European city busses running on wood gas from WWII. Running wood gas in a
conventional engine, 10 pounds of solid fuel produces the same energy as 1
gallon of gasoline. Current price for wood pellets is about $150 per ton.
or about equivelent of $.75 per gallon of gas. The wood gas in only
produced as it is pulled into the engine or fuel cell.


Just because you 'can' do something, doesn't mean you should.

Doesn't mean you shouldn't either.
