Being cyclical is not enough. The problem is hysteresis. The water->hydrogen step is the reverse of the hydrogen->water step, but it has a large amount of hysteresis. That is, there's a large gap between the energy put into the first step, and the energy given off in the second step.

Currently the hysteresis is enough to make hydrogen fuel cells no more efficient or only very slightly more efficient than an ICE.

I understand your point, but if the HFC can be developed to the point where it is just as efficient as the ICE, then the point is the cycle. I don't think that they are there yet myself, but it is good to see people are still working on it, pure EVs will only go so far I think.

The pollution alone would favor the HFC.

EV's have a more promising future than HFC.
