Hydrogen vs. Battery Electric Cars

Maybe this addressed elsewhere, but in the short segment on efficiency we get a single statement “if hydrogen is generated by electrolysis…”, but almost no hydrogen IS generated by electrolysis and prospects that that will change aren’t good. In reality, almost all hydrogen is generated by steam reforming of methane, or worse, by steam reforming of coal. While the electric grid is getting greener with the growth of renewables supplanting fossil fuels in electricity - and doing so in an economically competitive way - that is just not currently in the cards for hydrogen.
