That's a completely ignorant statement. Hydrogen cars actually exist and work exactly as advertised. There are no fundamental challenges. This reads like one of those anti-BEV posts from a decade ago. In both cases, the author is totally oblivious to the current state of technology.

Hydrogen cars are EVs. This is a deep misunderstanding of the issue.

The production and storage of hydrogen is expensive, had the downside of requiring a large tank in the car and is less efficient than just using a battery.

The cost will drop to nearly zero, just like the rest of renewable energy production. Tanks are cheaper, smaller and lighter than li-ion batteries. Fuel cell cars are also EVs, just like BEVs. The "efficiency problem" is greatly exaggerated.

How and why? I could say the same thing about batteries..

I assume hydrogen might be the best option for lorries and other heavy vehicles but what are its advantages for personal cars?

[_hypx]

Batteries will always been heavy and be dependent on large quantities of mined materials. The advantage of hydrogen is that it is made from water. So the raw materials used to make hydrogen will trend towards zero, similar to what happened with wind and solar.

And if by that you mean very badly and very impractically then you are correct.

> There are no fundamental challenges.

Except, you know building them cheap at volume. Just a small thing.

> This reads like one of those anti-BEV posts from a decade ago.

Except it also reads like anti-Hydrogen EV post from a decade ago and since then BEV have made utterly insane amount of progress and hydrogen vehicles are still in the utterly sorry and embracing state they were 10 years ago.

The Toyota Mirai is a hydrogen Fuel Cell car.

BMW tried to create a hydrogen ICE: https://en.wikipedia.org/wiki/BMW_Hydrogen_7

I probably should have said "fuel cell cars are EVs." But yes, you can make an ICE powered by hydrogen. It is likely to be a niche product, mainly sports cars and perhaps some diesel engine replacements.
