Yes they exist, however the hydrogen is difficult and expensive to store
(e.g. in astronomically expensive palladium and the range is poor. Moreover
you get less power from the same engine from burning it - much more
noticeable than LPG.
So practical it ain't.
OTOH if we can get tokomaks working then it would be a long time before we
ran out of deuterium to power electrolysis to make it.
