The process of electrolysis requires energy. The trick is how much energy is required to make a tank of hydrogen for a car, what is the source of that energy, and what is its carbon footprint including production and delivery.
Personally I don't see Hydrogen being very popular but I could be wrong. If it becomes popular though, then fantastic! It will be yet another green alternative to oil and gas, and that's what's really important.
