The theoretical highest efficiency you can theoretically get with a solid oxide fuel cell like the ones I started my career developing is Carnot Efficiency, about 64%. In reality, you might get 40%.

That sounds fair. Hopefully that might change in the future with different techniques. If the choice was ever between hauling petrol or water I'd take the last one.
I read it completely wrong. It doesn't use any new new hydrolysis splitting technique..
It looks like just standard direct-injection hydrogen into an ICE. Then it uses water injection every other time or as needed to be a quasi 6-cycle steam engine. Already been done. Smaller radiator probably or perhaps one day no radiator will be needed. That water injection stroke also cools the motor from inside the cylinder. Hot-Cold-Hot-Cold. There is still a H2 storage tank but it's more efficient than H2 alone. Here I was getting all hot n bothered but am now disappoint in ya'll Toyota.
