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.

I understand what you’re saying but take issue with saying that Hydrogen is not a fuel. To me a fuel is some material that can be used to provide energy for some equipment or process. Hydrogen is exactly that. I think what you mean is that it isn’t a net energy source given the energy required to isolate it.
