It's been a crazy week what with the huge news coming from the Supreme Court last week. I've left this window open because I wanted to reply when I could.
About 10 years ago, I think it was, Honda was delivering home hydrogen .... I'll just say machines since I don't remember what they called them, and a hydrogen powered car. If I remember, they were making maybe a few hundred, maybe a few thousand for like $75 or $100K. Like I said, it was 10 years back and I don't remember exactly. I know there was a list to sign up and I signed up but didn't get the call to buy one.
All of the major American-named, though foreign-owned brands are still working on hydrogen fuel-cell cars. Modern fuel-cell research is more about using hydrogen to power an electric motor and the electric motor to drive the vehicle. Just like electric today, if you don't count the filth of the battery and the environmental concerns of the hydrocarbons powering the electric grid, electric vehicles use far less energy for motivation.
Hydrogen actually is, or can be, safe, the Hindenburg wasn't. Hydrogen is 100% sustainable for the life of the planet. It is also 100% pure, clean energy. It beats nuclear, solar, and all hydrocarbons, for the environment. It beats electric vehicles powered with coal and lithium.
I'm fine with gasoline and diesel vehicles. I'm fine with dirty electricity powered vehicles. I do have a problem with all the motors and all the batteries made in China with lithium mined by children. My opinion and my hope, though, is that hydrogen is still the long term future of vehicular motivation.
