Reading the article, it sounds like they're focusing hydrogen for heavy goods vehicles while EV for private 'light' vehicles.
It'd be better if it was ALL hydrogen as it's an effective source of energy but I suppose if you work out a way to use it for all vehicles while effectively store and produce it at home, it's harder to justify why the west should give a fuck about anywhere else.
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.
