That's been one of the more entertaining myth's of hydrogen powered vehicles, notwithstanding the fact that it simply isn't true.
BMW had 5 and 7 Series hydrogen powered vehicles back in the early 2000's (2001-2003) that drove from the east coast to the west coast on nothing but hydrogen fuel.
The cars performed flawlessly.
I managed to drive one of the 7 Series hydrogen powered vehicles when they were in Chicago at that time. I couldn't tell the difference driving the hydrogen powered 7-Series vs. the conventional gasoline powered 7-Series. Both were literally a dream to drive.
As an FYI, I'm not a "green power" nut and my interest in hydrogen powered vehicles back then, as it is today, is purely in the interest of the United States of America achieving energy independence so we stop sending hundreds of billions of dollars a year to turd-world islamic states that hate us and want to kill us.
I've also purposely not commented in this post about the cost effectiveness of hydrogen powered vehicles. All I will say on that topic is that like any other "new" technology, it's expensive as all hell when it's first created however commoditization, mass production and mass acceptance always drives the cost down to an affordable level.
Henry Ford knew that with the Model T and all the technology and work process innovations it drove.
Fireball !!!
Maybe hook-up a fleet of hydrogen engines to the solar generators out in the desert between Blythe and Palm Springs.
So far, Google has failed to produce the power needed to make payments on their government subsidized loan.
