A friend of mine was an engineer for the GM fuel cell projects in Honeoye NY. There were a bunch of retro-fitted production cars running around, and the skateboard chassis was pretty novel for the time. They were convinced that GM was going to produce a hydrogen car as the tech was ready to go. Then, without warning, the Honeoye research center was closed and research 'consolidated'.

But, GM has invested a huge amount of money partnering with other firms for continued research, so I figure that at some point, GM may be hedging that EV will be a fad more than a practicality.

And, on the plus side, the biggest fraud in all of autodom, Elon Musk, has consistently said that hydrogen cars are stupid and not going to be successful.

I'm going to side with REAL engineers at GM on this one.
