I have this idea for hydrogen to be created on site at gas stations and behond that for communities to switch to a hydrogen economy. But I need a scientist to tell me if I can accually do this.

I am not expert but that seems to be a bit too combustable and unstable to use effectly...but again what do I know...HAHA...great idea though if it will work. I hate being strong armed into having to buy gas....

Dear Evan,
The process is one of electrolysis. The implication of this is that assuming you use the resulting Hydrogen in a fuel cell to produce electricity and run an electric motor to drive the car, both at 100% efficiency, then the delivered energy is exactly equal to the electric power originally used to produce the Hydrogen.
Unfortunately for us, the second law of thermodynamics ensures that each one of the steps,i.e., generation of hydrogen, conversion in fuel cell, and the running of the electric motor to run the car, is well below 100%.
If electricity is produced at the generating station by the thermal process, the pollution will only be centralised. You will have to think also of losses in distribution of enormous quantities of power to the hydrolysis plants distributed countrywide.
Not a workable proposition as it stands, in my opinion.
