Of course, if you want your hydrogen as H2, then absent

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.
