I doubt it somehow, Hydrogen has already been dismissed by many.
And many countries are forging ahead with massive investment in it, Spain and Brazil for example.
I wouldn't base your view on a single, and in many respects inaccurate and or disingenuous presentation.
For example the lady goes on about buses in Wiesbaden, certainly giving you the impression that they were abandoned because of big problems with the technology. This is not the case if you actually look into it.
The reality is that in Germany, and elsewhere, most operators of hydrogen buses are actually rapidly increasing their fleets, not getting rid of them.
There are certainly issues with adopting hydrogen on a large scale, just as there are with battery EV. But it has many advantages and, if implemented using green energy for production, is potentially far more environmentally friendly.
Fuel cells use rare materials like platinum and iridium, but in tiny amounts compared to the quantity of material required for a lithium based battery. Look into how lithium is actually produced, and the environmental damage caused in its production.
This needs to be factored into any discussion around battery EV, but is often completely ignored, either through ignorance or wilful blindness.
