I drove 1800 miles in a Hydrogen Car

Is anyone working on a plug in hybrid type hydrogen vehicle? I think that if its possible to get say 150km of range out of the battery alone and use the hydrogen for all longer journeys, you would end up with a vehicle that is much more energy efficient for most tasks, cheaper to run, and cheaper to produce, but still has the range of pure hydrogen or expensive battery EVs. Really its a best of both world situation for most consumers.
