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.
Not really. With high temperature process for instance, producing the hydrogen under pressure only takes like 1% more energy.
Sticking two electrodes in a glass of saltwater and then compressing that hydrogen to useful pressure takes a lot of energy.
There are some complications with hydrogen but most of what you hear is FUD. Usually from EV crowd because most hydrogen now is made from fossil fuels.
I found a writeup once of someone who built a solar hydrogen power generation system for his home. He had to use multiple 500 gallon propane tanks (which wasn't ideal because they apparently were "leaky" to hydrogen, but it was the only thing he could reasonably find to use) to store all the hydrogen he needed for the system.
But if you lived in the woods somewhere in the middle of nowhere, that kind of thing might work pretty well.
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.

producing hydrogen at home is indeed very easy, the problem is producing enough and compressing it to be viable.

Hydrogen is very leak prone and worse it makes metals that it's exposed to brittle (hydrogen embrittlement).
It's not as simple as it sounds on the surface.

In layman's terms, we would call that a bomb.
A 500 gallon propane tank filled with propane is also a bomb m8.
Granted the propane tank is likely not rated for H2 and will leak for sure, but just keep anything with the potential to spark 15 ft away
If you wanna make your own fuel, hydrogen is just an extremely hard way to do it. You can make ethanol or methanol more easily.
Or biodiesel. It's easier to find cars to modify for this.
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.
Noooooooooo you're only supposed to read headlines in current year REEEE!!!
