In reality, the moment hydrogen becomes comparably as cheap and available as gasoline or diesel, it is likely the end of the BEV. It is the availability of fuel that is the fundamental problem right now.
The EU has mandated that every "major highway" must have a H2 depot every 2-300km, can't remember exactly.
But still you need to get it made somewhere, preferably not from natural gas, because that's just stupid. It needs to be transported to a station, by truck, on a regular schedule or it'll stop working.
Compared to EV chargers which are, in essence, glorified power outlets.
The problem with "power outlets" is that they're heavily dependent on fossil fuel power plants. Since it is an unpredictable variable load, even more so than you think. Which is why it is really a transitional solution. From the beginning, it was about replacing distributed emissions with centralized ones, usually far away from cities. At some point, it became this green fantasy that could seriously replace fossil fuels. It is highly unlikely to do so in reality. Even BEVs will need hydrogen power plants to solve variable grid load problems. Eventually, you'll realize that hydrogen is a mandatory part of the problem, and the battery becomes redundant if not a negative.
Currently the grid over here is producing 17g of CO2/kWh, pretty much 90-95% is either nuclear or renewables. We're also exporting a portion of our excess to neighbouring countries.
The fact that Americans can't modernise their grid doesn't apply to the whole world, you see.
In reality, hydrogen is much cheaper than expanding the grid. You are basically dismissing basic physics with nationalism. Whichever country you're from, it too will find out that is cheaper to build a hydrogen network rather than massive grid expansion.
As for "hydrogen network", we have pretty much zero infrastructure bringing natural gas or any kind of gas to residential homes. I think the capital city used to have a gas pipeline, but it got dismantled and people just use portable CNG tanks.
Hydrogen is a lot cheaper to move around than electricity. Regardless of where you are now, it is more logical to build the hydrogen network rather than expand the grid: https://www.brinknews.com/could-hydrogen-replace-the-need-fo...
According to him transporting H2 is THE biggest problem. There are too many conversion losses in the process.
