Hey Scotty...have you seen this article about a company that has figured out how to make Hydrogen safe?

Experimentation with hydrogen-powered cars has been going on for a very long time, it's likely to be still longer before it's really practical.

I meant to add, if the hairstyles don't give away the era, that is a hydrogen-powered AMC Gremlin. It's been a long time coming...

Beware, the vast majority of these "breakthroughs" turn out to be gimmicks to drive stock prices.
I did more breakthrough are gonna happen with both hydrogen and electric cars. They are gonna get reliable and more affordable with time. It is gonna take time to build infrastructure I say 30 years but yeah who knows?
I'm glad to see progress being made. I believe Hydrogen will be the way forward. But I agree with @CarlJason98....it will be a long time before we get an infrastructure in place.
