Ah. Direct injection H2. (Essentially a Diesel engine running hydrogen.)
Thus, the low octane (MON) doesn't matter.
Most definitely not a converted vehicle.
100 of these vehicles produced in total. This beast got only 16.9 MPG on
gas, 4.7 MPG on H2.

Well, yes - why would you want an internal combustion engine running on
hydrogen?
I don’t know the answer, but at one time BMW thought it was a good idea. I
drove the result of their work - a bi-fueled series 8, and loved driving it (it
was *not* a disappointment), but why?
Sure, reduced emissions compared to the gas alternative, but a fuel cell can
perform so much better with zero emissions.

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 further detriment to the engine HP.
Yes, you can make an ICE run on H2, but it will be difficult and the result
will be disappointing.
It begs the question; Why would you do this? Just run the engine on methane
(MON 120) and skip all the fuel conversion effort and energy losses.
Better yet, skip the electrolysis step and the H2 transport, and run an
electric car directly on the electricity delivered right to your house already!

2. There are billions of ICEs already in use. They can be converted to
run on H2. And they will be able to claim they are "green" because
pollution at the vehicle is considerably reduced (it moves to where the
H2 is manufactured).
