Hydrogen engines -

There are some problems with power output for heavy use hydrogen engines. Deutz, for example has built a 7.8 L hydrogen engine, based on their diesel of the same capacity, but only achieved 180 kW from it. They state it could not compete with diesel unless they could get 250 kW out of it. Ford has built some prototype heavy engines such as a 6.8 L V10., also needing more output for production.

Hence the move to fuel cell vehicles.

Electric engines in vehicles are a mature technology.

There is no doubt that FCEVs work well, but there are some significant attendant issues
Hydrogen engines ie reciprocating ICE hydrogen engines, seem like an utter dead end.
The Engineering Explained video in post #2 makes that very clear, and while interesting, it is hard to see why Toyota even bothered with the project.

I was going to say, the article linked in the first post was out of date, the EE video explains what the problems are and where we are right now. Also leads to some suggestions where the Hydrogen IC engine might be a viable application. The way it stands right now, it seems electric is the way to go.

Toyota is a global leader in sales hence they don't want to have to license some innovation they overlooked, that's why they built the Hydrogen engine. Now they know.

I watched other videos presented by Munro, and everything he says makes intuitive sense.
The hydrogen disks sound very interesting, and aside from anything else, it reminds that it pays to not assume that the technology everyone is yapping about right now, will be The technology in 5, 10 or longer years.

If we could predict the future we would all currently be lotto winners!
That's true. But it doesn't stop people making claims like "this technology will be the only technology going into the next century", even though that is 90 years away.
