Hydrogen makes up 0.00005% of the atmosphere which makes harvesting it from the air not feasible. To refine from water takes more energy than you get back which makes it an energy storage medium not a fuel. Compare that to oil, coal, natural gas etc. which is the result of millions of years of (mostly) solar energy being concentrated into a small space. And you get much more energy back versus what is needed to bring the energy to market.
To put fossil fuel into perspective a Tesla battery weighs 1000+ pounds and contains as much energy as less than 2 gallons of petrol.
