No they well informed much more then you and me, and your talk above shown you are the one that clearly don't understand the difference between Hydrogen Fuel Cells and Hydrogen ICE. Again, read all the article and what market analyst talk about, it is the Hydrogen ICE that big auto company now working as they also understand the problem with hydrogen fuel cell.
What support system, you ask? Do you understand what is ICE support systems means? It means they will use capabilities of existing ICE garage, existing vendors, existing spare parts manufacturing. Hydrogen ICE whether for Auto, Ships or Plane will use existing fossil fuel engine tech and only major different instead using gasoline, diesels, avgas/avtur, they are using Hydrogen.
Put it this way so you are not confusing again between Hydrogen Fuel Cell and Hydrogen ICE. Both Batteries and Hydrogen Fuel Cells are both electric vehicles. Hydrogen ICE is not. It is ICE vehicle. You say people understand the difference between Hydrogen and Batteries car, but at least yourself don't understand different between Hydrogen ICE and Hydrogen Fuel Cell. Cause you still lumping Hydrogen Fuel Cells with Hydrogen ICE as one, despite all the articles above and all before that's being put. Again even tough both fuel by Hydrogen, it is very different tech altogether.
The difference is the need of huge batteries cells. Hydrogen Fuel Cells still need huge batteries, even tough not as big as pure EV batteries car. Hydrogen ICE just like current fossil fuel ICE don't. That's the problem, batteries is expensive and despite all the drives for better batteries tech, it is for most people in the world, still more expensive then the alternative
Politicians are forcing electric cars on a public that doesn’t want them

I can assure you most people in the world still not want EV. Looking at the telegraph article above clearly not even all European like to think about EV as most Scandinavian do. The World will not become Greta's La La Land thinking. That's the fact, as most people in this world even in Europe can not afford North European standard.
I come from country that sit on most World Nickel reserve. Having the ambition became World leading batteries producers, and work on that. Even then, behind the fan fare also working on increasing hydrogen production potential especially the Blue Hydrogen (as we are also sitting on big natural gas reserve), even tough they call it Green Hydrogen. Is it because due to Hydrogen Fuel Cells? No, they are waiting and betting as most in automotive and propulsion industries, on the development on Hydrogen ICE for all type of transportation.
Do you think Ships or Plane will move to Batteries? No they won't, as it is too heavy. Even with the so call potential solid batteries tech wonder. Personally I can see some in urban transportation using more batteries, but long range inter cities and heavy transportation still using ICE, whether hydrogen ones, alternative synthetic or hybrid fossil fuels. Europe will want to stop fossil fuels cars? Well that's EU goal, and not most others goals.
Btw where those electricity coming from? Wind, solar? EU better think back to accept Nuclear ones, or that electricity still come from Fossil Fuels as presently where those EV being charge using electricity from fossil fuels.
Well not what most of oil companies think, as they see their 'Blue' hydrogen can use on modified their current existing distribution network. That's why billions being build on hydrogen capacities production.
People will move on energy that can be afforded by them not some Green energy La La Land. People with high living standard in North Europe will think differently from most people in Global South. However as last article I put in previous post, it is where the unbalanced energy consumption will come. No batteries, or any other Green La La Land energies can be afforded by most people in this world. This is why Hydrogen being seen as attractive alternative, as they can be produce and manufacture using different methods whether Green ones, Blue ones or Grey ones. All depends on each economies wallet.
Then again even hydrogen will not and can not answer all the energy demand surges. Fossil fuel reserve is dwindling anyways, but doesn't mean it will go away especially in Global South. People that come from High Income economies can preach whatever on dangerous of Fossil Fuel to climate change. However majority of people in this planet are from Global South, where majority of them only think they need energy, and that energy must be affordable. Don't preach on children sake, they're doing their best for their own children sake with what resources that they can afford.
