> Finally, electric cars charge at ~96% efficiency, while hydrogen is something like 40%. >> This claim has little substance and credibility. The efficiency of hydrogen fuel cell vehicles versus battery vehicles is considered in some detail in this video [1]. The conclusion [2] is that, in the best case, the energy efficiency from power generation to road for existing or near future hydrogen fuel cell vehicles is about 25%, compared to about 65% for typical existing battery vehicles.
