An idling gas engine may be annoyingly loud, but that's the price you pay for having WAY less torque available at a standstill.

I dunno, I've never looked into them. How do they stack up against electric motors in everything else, and is the hydrogen expensive to get?

    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.
