Hydrogen is great rocket fuel.
I see little future for the private vehicle though and Toyota is making a big mistake focussing only on Hydrogen fuel cell EVs. Other car makers have already abandoned it or just want to offer Toyota's version rebranded.
It will stay a niche except in Japan where no doubt Hydrogen infrastructure will be installed for their largest car maker but I have serious doubts you will ever get Hydrogen on every servo here in AU.
It is still complicated stuff to manage safely.
However that might change once we have developed small scale Ammonia fracking directly in the vehicle so there is no need to have the Hindenburg compressed into a tank in your boot.
This is currently done(test field) by Fortescue Future Industries using Green Hydrogen converted to Ammonia for heavy industry, like ships and trains but I don't see this working in the near future for our little cars. I don't even think there will be a demand for it and PEVs are rocking along quite nicely(except here).
Unless direct come here into play.
I didn't bother watching the video but we already know that Green Hydrogen is still only getting ready to grow up, heavily pushed by FFI and a few others who will be using their tech so it will be able to replace blue hydrogen, 5-10 years from now.
