Production, consumption, electrolyzer efficiency limits and capital cost, storage problems, fueling problems, transportation problems, pretty much every aspect of this stuff makes it terrible for use as a vehicle fuel. All green hydrogen efforts should be focused on fertilizer production before anything else.
Why do you think that? The fuel production side or the fuel consumption side?
