Hydrogen vs. Battery Electric Cars

Elephants anyone? Three points:

First, given the massive difference in overall efficiency, and the fact that electrolysis of water requires electricity, does it not make sense to make the most efficient use of it?

That brings us to the second point, only electrolysis was mentioned... giving the misleading impression that that is the norm. AFAIK, that is not so, the vast majority of Hydrogen is obtained from steam reforming of natural gas... So in the end, Hydrogen is sort of just another fossil fuel... Or to put it another way, Hydrogen NOT an energy SOURCE, it is a means of energy storage and transport, one which is far less efficient then other options.

So third, in the end, the energy of hydrogen comes from electricity, so if the concern about BEVs is that they will over load the grid, then what is going to happen when dramatically more electricity is used for hydrogen, to achieve the same distances driven?

Bonus Questions: How much electricity do refineries use? Hint: If tomorrow every single car was a BEV, charging on the grid, BUT all refineries were shut down permanently, what would be the NET change on the power grid? Don't forget that all refinery related trucking and ships would also stop... Do we suddenly have a surplus of electricity?

Now I understand that Toyota is paying for this video, but still ...
