95% of the hydrogen produced comes from natural gas (ref DOE). Just burn the natural gas (if you want to use an internal combustion engine)
If you are going to use electrolysis, why not directly use the electricity that process requires, instead of using it to make hydrogen? That was my point, hydrogen by those methods is a storage medium, not a fuel in the sense that we have any reserves of it.
Here in Vancouver we are home to Ballard, a leader in fuel cells. However, the buses that are being replaced by our transit system are largely trolley buses, since they are cheaper than fuel cell buses and skip the hydrogen step, turning mains power directly into traction at the wheel motor.
