Cars that run on hydrogen emit zero carbon at the tailpipe, but 96% of the world’s hydrogen is still derived from fossil fuels like methane gas.
That makes most hydrogen-powered cars much more polluting than battery electric vehicles, or EVs, and only marginally cleaner than traditional combustion engine cars.
Toyota is supplying the Game’s official fleet, which includes 500 Mirai cars and 10 coaches that run on hydrogen, as well as 1,150 EVs, to ferry athletes around.
It is also one a few major automakers betting on hydrogen-powered vehicles, as well.
Hydrogen vehicles have so far failed to take off as a popular choice for consumers, and very little infrastructure to refuel with hydrogen exists.
