Funny, because the economics of hydrogen is heading to nearly zero cost. This is the same trajectory of wind and solar. All of these things have one thing in common: They all are made from practically infinite and free resources. Wind, sunlight and water are very cheap after all. This will imply that hydrogen will also be very cheap.

Also, hydrogen is more ubiquitous than electricity. In fact, it is cheaper to distribute hydrogen than electricity, simply on account of how pipes work compared to wires.

In short, if your argument is economical in nature, then your conclusion is profoundly wrong. It is a matter of when, not if, the lower cost basis of hydrogen based vehicles will cause them to displace BEVs. Also, BEVs have major environmental and practical downsides. I suspect that once the hydrogen movement gets going, BEVs will not pose much of a fight. It will be discarded as just another transitional idea. After all, FCEVs are also EVs.
