The comment you’re replying to is deleted, but from your comment I assume it was about hydrogen as fuel?
Hydrogen fueled vehicles are generally electric, using a hydrogen fuel cell, rather than being internal combustion using a hydrogen engine. Compared to battery electric, hydrogen has the benefit of fast refueling and higher energy density, but has the drawback of difficult storage and lack of refuelling infrastructure.
As a vehicle fuel, I think hydrogen does have a future, but only in commercial/industrial, particularly shipping. Semis already have predictable routes and stops/depots, and building hydrogen refuelling stations into those depots wouldn’t be too complicated.
Hydrogen passenger vehicles, with gas stations being replaced with hydrogen stations, will never happen.
