You mean from 20% to 80% charge? Which is realistically only 150 miles of gained range, and that's assuming everything is working at full power. The alternative gives you 0-100% in 5 minutes consistently. And best of all, it can be scaled up to trucks and above without suddenly realizing you need megawatts of power per station.

In reality, the charging solution is much harder. We've just normalized the idea of using electricity to charge things when it is actually a bigger challenge than dealing with fuels.

One refueling station can serve thousands of customers, but a charging station needs multiple hours to charge each car. So you need far fewer gas stations. This is why the economics of gas stations worked out in the first place. Before, people bought tanks of gasoline and refueled at home. The gas station model was cheaper.

Not everyone can recharge at home. Hydrogen have all of the same advantages except recharging at home (and even this is a "kinda", because home refueling is possible, and plug-in cars exist).

The problem is that we are hitting the limits of the BEV, and no amount of handwaving is going to make the problems go away. This mirrors the push for ethanol powered cars, and sudden realization that we cannot grow enough corn to make it happen. And fantasies about how China or whatever solving the problems is just a repeat of cellulosic ethanol, which was suppose to magically solve the problems of ethanol production.

Again, not everyone can do this. You will have to have public chargers. Plus fast charging for long distance driving. This will still require millions of charging stations, far more than any technology that allows you to refuel.

That's the point: If you can refuel instead of recharge, you don't need that many stations. The number of hydrogen stations would be the same as the number of gas stations. And you have it backwards: You need vastly more charging stations than refueling stations. The US has something like 150k stations, and it's not even close to being enough.

Then you are just being old and outdated. It is totally safe.

You will need millions of charging stations everywhere. Both AC and DC charging stations. It is actually less straightforward once you go beyond home recharging.

And a lot of people can't charge at home. You will still need public stations.

In the end, this is just the whining of a handful of rich people. If it is more straightforward to get everyone to refuel at public stations, it is the better solution.

2/3 is still not 100%. And you can refuel at home if you really wanted. In fact, you can even refuel a gasoline car at home. But in reality this was never a major selling point. It's just the crutch BEV fans are relying on. The refueling infrastructure is the only thing that really matters.

The only reason why we see BEVs today is the obsession to be green. If that wasn't there, BEVs would still be dead. It has not come close to solving the fundamental limitations of batteries. One of which is that you need a huge charge infrastructure, something that will be more expensive than its backers think.

Hydrogen cars do not necessary need a battery, and only use it for regen power. This is the equivalent of a hybrid car. A hydrogen car is also 100% zero emissions unlike a petrol car. The main point is that a hydrogen car fully replicates the experience of an ICE car. For millions of people, that is an absolute necessity.

We've been doing it for over a decade now. It is shown to be safe.

A 700 bar tank will store more than energy than a similarly sized li-ion battery.

As an energy storage system for cars, the problem is already solved. People are just repeating the same anti-progress rhetoric that was used against battery cars.
