actually if you use the more efficent varieties of Electrolisis, which are about 85% efficent, and fuel cells which are about 90% efficent, you get 75% of the energy back from the process.
Modern batters suck. They are too slow, large, heavey, and lose thier charge over time. I would surmise that batteries are only about 80% efficency, but they have a limited output. Things like accelleration, towing force etcetera are laughable on battery powered vehicles. If you want to look at it realisiticly, H2 is just a matter battery, with none of the downfalls of a chemical battery.
Switching from once fossil fuel to another is just... well stupid. And I don't know the industrial method for extracting Ethenol, but I expect it involves the purchase of an organic coumpound, and lots of time.
Hydrogen however is the most available substance in the universe. Hydrogen as fuel could be used in ICEs (Internal Conbustion Engines) such as what you might term the classical gas engine, though I was more referring to Tesla's Disc pump, which can be fueled by anything that creates a pressure differental of matter (79 years ago that was steam). But also Fuel cells whose exhaust is pure H2O.
Hydrogen is extensivly used in modern society, so the industry for its creation is already there. Beyond that, you could just make your own. I would expect that if cars actually used Hydrogen, it would be fesable to buy a device for about $400-$1000 U.S. that would simply be plugged into an outlet or run off of solar power, and be refreshed with water as needed, producing hydrogen and oxygen through electrolisis at as much as 85% efficency. Hydrogen fuel cells are around 80-90% efficent. Standard ICEs are 10-20% efficent, Tesla's disc pump is about 60% efficent.
There is a lot of reasearch into hydrogen and hydrogen fuel cells, so learn away.
At any rate water is cheap as hell, and contains alot of Hydrogen. Electricity is cheap as hell too (compared to gasoline & fossil fuels). So if I remember avigodro's number correctly (and I'm sure I don't) 20 kg of watter = 4 kg of Hydrogen and 16 kg of Oxygen. Now one of you chemists out there can tell us how much energy that is, but I suspect that much fuel would last you at least a weeks worth of commutes.
