Mega Bump!
Hydrogen internal combustion power is a still born looser. No one well informed takes it seriously as a solution.
Hydrogen fuel cells are the target of this research...........
Hydrogen generated in the way they state is not an energy source. It’s a method of energy storage, essentially a kind of battery.
You generate hydrogen by splitting water molecules using electricity, then you can burn that hydrogen in a fuel cell or internal (or external) combustion engine to produce work.
Problem is that the work you get is quite a bit less than by just running the initial electricity through a motor.
How much less I’m unclear. Would be nice to know.
You also have to generate this original electricity some way, with most electricity at the present time being generated using fossil fuels.
So the cycle is fossil fuel to electricity to hydrogen to work.
Anybody want to bet burning fossil fuel directly to generate work wouldn’t be more efficient?
I believe Hydrogen fuel cells are around 90% efficient. More than four times the efficiency of a typical car engine.
A 10% loss is not too much of a serious problem if you can get the power density you need for a transport fuel.
