It is cheaper than building out the grid needed to power all cars. In fact, you use basically the same land that gas stations current use up. It is quite straightforward.

Attacks on efficiency are anti-hydrogen FUD arguments. They were made up by BEV companies and are almost entirely false. It's important to realize that fuel cells are electrochemical systems just like batteries. FCEVs are also EVs just like BEVs. There is no fundamental downside. The upside however is that you avoid the huge amount of raw materials needed for the batteries. So this will be a far cheaper solution once we hit mass production.

In short, it is pretty much guaranteed that we will eventually switch to hydrogen cars. It is only a question of when and not if.

It really isn't. The grid is literally already there! The only new infrastructure needed is at the end point. If you are going to be generating hydrogen from electricity anyways, it isn't any different, except maybe you need less electricity because going from electrons to hydrogen back to electrons again you lose 40% energy.

The BEV companies aren't pushing FUD. They are just choosing the option that they see the most demand from, and can make the most money from. Japan has tried to make hydrogen happen for 20 years now, and it simply isn't going to happen.

Batteries don't require much more raw material than the fancy cyrogenic compressed hydrogen tank and fuel cell you need for a hydrogen car. Those batteries are also than those two things also.

That's complete nonsense. We will need vast amounts of grid upgrades to be able to be able to power all cars. And if the grid needs to be purely renewable, that problem explodes into something far harder. In fact, the problem becomes so hard that you will need hydrogen-based energy storage systems to make it work. But that completely undermines any efficiency arguments against hydrogen cars.

BEVs are over 100 years old. It is just a repeat of an obsolete idea. The moment we get serious about green energy, hydrogen cars will happen.

Hydrogen tanks are literally just tanks. They require very little raw materials compared to batteries. Fuel cells are tiny compared to batteries, and use up about the same level of raw materials as catalytic converters. Everything else is basically the same between FCEVs and BEVs. So you can quickly realize that the FCEV will be the far cheaper of the two ideas.

That is complete nonsense:

> A typical EV would require about 3,857 kilowatt-hours (kWh) of electricity. For 26.4 million EVs, that's over 101 terawatt-hours (TWh) of electricity in a year or about 2.5% of what the U.S. grid produced in 2020. Although it's a small percentage, it's much more than what we're currently asking of the electrical grid.

Let's say we have 100 million cars, that is 10%.

You keep saying hydrogen tanks are literally just tanks. I get it, you don't believe compression is necessary, so no cyrogenic cooling at gas stations (powered by the grid of course), no fancy compression in cars. Is that what you actually believe?

Now do the math with 300 million EVs. Also, assuming SUV sized ones being popular too, alongside many commercial vehicles too. It is not that simple. Especially since so much of it will be DC fast charging and not slow speed charging.

Compression is not that energy intensive. It's more BEV FUD to make this to be a big deal. If done correctly, it is only a few percent loss of energy: https://www.hydrogen.energy.gov/pdfs/9013_energy_requirement...

Also, it is recoverable energy. Compressed gases are energy storage mechanisms in their own right. In the long run, this will be very minor loss of energy.

Will it? Why?
