Enrique it is great to see you writing about hydrogen, thanks for posting.

But please be aware your picture of solar hydrogen infrastructure appears incomplete, which leads you to the wrong conclusion about the suitability of hydrogen for cars, as far as I can see.

It will be solar which is the energy source which ultimately feeds most hydrogen production, for many reasons, and a consequence / feature of this is that it will probably done on a community basis, supplying local microgrids, backed up by local hydrogen generation and fuel cells, this being the way to most effectively use solar. We will probably be economically forced to do it this way in the end, if it is not immediately accepted by funders that it has to be so.

I've explained the economic reasons for that in some of my own articles. It isn't simple, so will leave the details out here, but you can find more under "Kardashev Money" if you are interested.

The article you've cited arguing against hydrogen for cars, quotes the main reason as being lack of refueling points for cars.

Note that the article states the current situation, not any future situation.

Indeed there are not refueling points on every street corner, hower there probably will be, when the final solution of community solar is in place.

In fact this feature of ubiquitous refueling points in the scenario of community solar hydrogen is a major plus point in why it should be community microgrid based, rather than grid based.

If you are worried about your own EV becoming superseded earlier than expected, you should be assured that the other argument cited in that article is nonsense, as far as I can tell. Here is the passage: "A strong fuel cell makes a battery look even better because you can operate into that state of charge window and you can do a lot of things to operate more efficiently. Batteries are great for a lot of power, and the hydrogen fuel cell is great for a lot of energy on board, and the two are great complements."

To me as an Engineer, I can't make any sense of that passage at all, it looks like an empty, inane argument. Yet I happen to know the same argument has already been accepted as gospel by some younger Engineers and would-be engineers who do not have the experience/ confidence to question it, and there are indeed cars using batteries in conjunction with fuel cells, but there is no technical justification I can see, it has to be for commercial reasons only, it seems to me.

Anyhow, your EV should be easily convertible to dual hydrogen / electrical recharging by fitting an appropriate reversible fuel cell. I would expect a program to roll out community solar hydrogen infrastructure to include a component for upgrading all vehicles both EVs and internal combustion to hydrogen.
