I guess you have to define "a lot" but yes it does take significant energy to separate hydrogen from water.
another thing to think about when using methane is that a methane powered car would be cheaper to build, I know currently that is not true but it's only because you have to convert a regular car to methane. A regular car has lots of things about it that allow it to use gasoline both efficiently and to curb pollution. A car from the 70's burning methane is significantly less polluting than a car from the same era. It stands to reason it would be easier to build methane cars that pollute less than it would to make gasoline cars that do. So lots of expensive things that go on a gasoline car could be left off a methane car. Not taken off a gasoline car then made to use methane.
