NOT at less than 2 percent total system efficiency...But if you had a home based hydrogen maker you can pretty much keep it running at home at the price of electricity which has to be cheaper than the price of gas.
Here's the totals...
120VAC to 12VDC: 95%
12VDC to Chemical change in charging Battery: 90%
chemical change in producing 12V to power gas production - 90%
Hydrogen gas production: 5% (giving the benefit of the doubt re pressure)
internal combustion engine efficiency - 50%
Total System Efficiency = .95 * .9 * .9 * .05 * .5 = 0.0192, or 1.92%
This is being generous and using a high efficiency battery charger
Even IF we assume ZERO losses in storing electricity and retrieving it again from the battery (and, we KNOW that batteries aren't 100% efficient, as they get hot when charging and discharging) the electrical, gas production, and engine efficiencies alone are at only 2.4% efficiency...
