Electric vehicles have for years now been extremely popular with consumers who want to do their part to reduce CO2 emissions. Every major vehicle manufacturer is in the game to some extent, and companies such as Tesla and Rivian make nothing but vehicles that run on electricity.
But there is also a completely different energy source that can power vehicles in equally clean fashion. Automotive heavyweights such as Toyota and Honda are pouring money into related research.
Establishing these new drivetrains as mainstream would represent somewhat of a holy grail on the clean technology front, in part because one of the ways to obtain this fuel is to let it flow out of the ground from a renewable source.
That fuel is hydrogen and it has caught the imagination of engineers across the world because it burns without emitting CO2. This early in the game it is more costly on a per-kilometre basis than gasoline or electricity, but…
