Hydrogen is t a source of energy. It is a way to store energy.
The energy density of hydrogen makes it prohibitively inefficient with regard to storage and transport. Hydrogen has a tiny fraction of the energy density of diesel. This gives hydrogen powered trucks a much lower range than diesel or a reduced cargo capacity. Pick one.
Hydrogen produced at home by electrolysis would be a low pressure gas. It takes as much again more energy to compress and cool the hydrogen into a cytogenetic liquid. This energy is lost to the atmosphere when the hydrogen is burned.
A hydrogen powered car is just na electric car at about 25% efficiency with extra steps. The (small) advantages of range are not worth the cost and difficulty of dealing with cryogenic liquids that boill off even when stored in a double walled vacuum flask.
Modern industrial scale hydrogen production is from crude oil. That is why hydrogen is produced by the Shell Oil Company. It is dirty as fuck. I will tell you why if you ask.
Okay, a lot of confusion here.

I can't figure out why they use it.
U should post this somewhere else, too. Very succinct summary of the craziness of hydrogen. I don't hate the molecule. I just don't get it.
