Perhaps some day this will be true. However, the major 'biofuel' we produce in
the USA is ethanol and numerous studies indicates that the way we produce

I don’t remember the technology.
The switch from H2 to gasoline and back was seamless.
It was never made available to the public. It was only for technology
demonstrations.

Thus, the low octane (MON) doesn't matter.
Most definitely not a converted vehicle.

Sure, reduced
Gasoline engines are designed to run best on gasoline. They can barely
be converted to run on H2.
In a nutshell, H2 has an extremely low motor octane number (MON) of
about 60, and the compression must be reduced so much that the engine
makes very little power. The low charge density is a
Certainly H2 makes no sense for most transportation or most
