They didn't explain it away & I don't know enough about it to say one way or another whether it's a route not worth looking into.

It looks like VAG see it as another alternative because Audi are going to be rolling out a H Tron range, this in part due to the fact that in the US the E Tron range (same with BMW's I range & of course Tesla) will no longer be seen as Zero Emission cars because of the C02 in electricity generation & they say they're making Hydrogen without the use of C02.

Weather this is true only time will but at least they're looking at all avenues they may well have a breakthrough or they may not, EV's have been around almost as long as ICE vehicles & up until the last couple of decades they were also considered a waste of time so I'm open minded as to whether it's another viable alternative to the other two or not.

Hydrogen is either coming from cracking fossil fuel or from using electricity to electrolyse water. Currently, most hydrogen used industrially is from oil.

Maintaining a dependence on fossil fuels is dumb.

Using electricity to produce hydrogen to fuel cars is inherently, unavoidably, massively less efficient than even current battery tech.

Hydrogen fuel cell powered cars are not knitted out of hemp - for instance, the fuel cells use platinum as a catalyst. The mining of platinum is not pretty. I don't see any reason to believe that the environmental impact of manufacturing hydrogen fuel cell powered electric cars would be any less than that of battery powered electric cars. And internal combustion powered hydrogen cars are just an unspeakably inefficient solution.

Hydrogen cannot be made without energy. If you have zero emision energy/electricity the you can put that in a battery far more efficiently than you can create hydrogen. Hydrogen is just an inefficient battery. It is not a fuel its an energy store.

EV's have never been practical before because of the relatively poor energy density in batteries. Thats now changing. The EV drive train is way more practical than ICE. Its far simpler, delivers instant torque from zero revs.

Hydrogen EV's are still EV's. They are just an attempt to keep refueling similar to an ICE. In all other respects they make no sense at all. Its an evolutionary dead end.

Ford have announced plans to produce a completely (SAE level 4) self driving car within 5 years.

But they will only run them as a ride sharing service, no plans to sell them direct to public.
