FCVs are projected to be cheaper than BEVs by all the modeling in the literature.

Going with a lower pressure tank saves money at the cost of reduced range. The problem is booting a hydrogen station network big enough to support a low range FCV (< 200 miles).

But even building expensive carbon fiber high pressure tanks is going to eventually be much cheaper than huge batteries filled with semi-rare minerals that will increase in price as battery market demand increases. We should talk about what peak <Battery Mineral> will mean alongside Peak Oil.
