First, you have a $10K wind turbine generating electricity. (That
means, a really SMALL one! A house requires more like a $40K
turbine...) Now, you take that perfectly good electricity, waste 30%
of it, and generate hydrogen. You pump and compress it (taking up
another 10-20% of energy) and put it in an internal combustion engine
designed for natural gas. You use it to displace, asy 20% of the
natural gas used by this engine.
So, lets simply compare the costs of the hydrogen vs. the cost of the
natural gas it is replacing. The natural gas probably costs less than
$50 per fill up. Your wind system with the turbine, electrolyzer (by
the way, have you priced these?) pumps, compressors and other
equipment actually cost around $15K, so just the interest on these is
$600 a year. Assuming a 10 year life (if you are lucky!) then the
cost per year is $2100. Yes, I am being very, very optimistic on
these prices. Reality is probably 2-10 times worse! so, if you
normally fill up weekly, you get:
Pure natural gas
$50 per fill up
52 fill ups
$2600 a year
Now, you hydrogen system is to defer 20% of this, so your system is
natural gas
$40 per fill up
52 fill ups
$2000 per year
$2100 per year for hydrogen
$4100 per year for your hydrogen scheme.
I, personnally, don't have an extra $1500 a year to play with
hydrogen. Do you?
You are better off using the wind system to charge batteries, and buy
an electric vehicle by an order of magnitude!

And the power that produces your bogus gas comes from your Gasoline. It
isn't free. You really believe your battery has endless power by itself?
In my first post, i already said that use wind turbine to generate
electricity and than use the electricity to electrolysis water to get
hydrogen and than pump/compress the hydrogen into the gas tank.
That is how you can blend hydrogen with CNG to run our car.
You want to distort my original idea, i can't do anything.
There is a project by Idaho National Laboratory under U.S Department of
Energy that do experiment of running vehicle with Hydrogen+Natural gas
mixture
