FCEV vs bev: when does each make sense?

Both battery electric and fuel cell electric vehicles are seen as viable emission-free options for heavy-duty trucking, but each has its own unique use cases where they perform best. So, when exactly does it make sense to choose hydrogen, and when does a battery do the trick? Hydrogen FCEVs show advantages over batteries for the heaviest and longest of hauls, while BEVs are often better suited for lighter loads and more frequent stops. This is because hydrogen weighs less per unit of energy than batteries, creating a curb-weight advantage and allowing for heavier payloads and longer driving ranges than that of its battery-electric counterpart.
