IDK why hydrogen just hasn't captured any mind share. Seems like a great technology.
Someone will be along in a moment to tell me all about embrittlement and blue hydrogen, yet conglomerates are pouring many billions into water cracking infrastructure right now.
Hydrogen cars have limited performance, are overly complex and there's no infrastructure. For an average consumer they make zero sense

Why ask the question if you already know the answer?
The reason it hasn't taken off is because it's a fundamentally very difficult technology to safely build. Embrittlement is a fact of physics, and it's extremely difficult to design around, especially at scale.
And the fact that there is almost zero global capacity to manufacture green hydrogen means that there is little point in subsidising it from an environmentalist point of view.
Hydrogen will have its uses, maybe in niches like aviation fuel where requirements are very specific and it's possible to exercise much tighter control of the infrastructure chain. But it's just not a competitive technology for replacing petrol and diesel in general purpose road vehicles.
Why ask the question if you already know the answer?
Because these problems are not prohibitive. Any tech has challenges.
A brief perusal of anything about embrittlement suggests that it's very manageable. There are hydrogen powered vehicles driving around right now. How is it that their tanks to not crumble or shatter?

Imagine saying "There's not a lot of computers around, therefore this internet isn't going to be viable". In Western Australia there are three large scale hydrogen production facilities under construction. The one nearest me will cover 15,000 km^2 and produce 3.5 million tonnes of hydrogen per annum. Do you really want to bet against mining consortiums contributing many billions of dollars to hydrogen production?
We can go back and forth about which ought to be a better technology, but one is practical now while the other isn’t. One has much smaller infrastructure requirements than the other. One let’s us refuel at home while the other doesn’t
I personally will be happy to see almost the entires gasoline industry disappear. Imagine making such an impact on ground and air pollution, when the goal is simply to reduce carbon emissions. Imagine how much it simplifies all of our lives to just plug in every night
Critics of hydrogen cars are repeating the same criticisms of EVs just before they took off. Same can be said of wind power or solar power. In reality, it's just the same anti-green and anti-progress BS you hear about any new green technology. It's all the same story.
Meanwhile EVs have taken up a significant share of the market while hydrogen is still niche.
LOL
Seems fair enough. I can imagine "first world" countries having much more than a 30% ev adoption rate especially in cities. For everywhere else though alot of the infrastructure that EVs rely on (power grids, electric charging stations, specialist mechanics, hell even well maintained roads) just doesn't exist in a large enough capacity. For an international company like Toyota probably does make sense not to go all in on ev's but to have a sizable fleet of both types of vehicles for all markets.
