Of course, if you want your hydrogen as H2, then absent ultra-cheap energy H2O isn't the best source. Energy costs, and cracking CH4 takes far less energy than cracking H2O.
There have been a few small demo projects which have used electrolysis for making hydrogen, usually due to special circumstances of one kind or another. For example, if memory serves, there are a couple of H2-powered buses in Iceland, and their fuel station uses electrolysis because Iceland has (a) lots of hydroelectric and geothermal power, and (b) no natural gas. 

Town of Hamburg in Germany has collect most vehicles from a Euro wide
H2 powerd public transport evaluation project (CUTE) and runs them 
satisfactorily.
( thought the initial "full path" fuel economy was about 100l/100km per bus, 
abysmal ;-)

The H2 Fuel is  produced via elektrolysis.
IMU powered with surplus grid power.
