There's some interesting info re the relative capital costs of H2 refueling per event versus QC/event as well as BEV versus FCEV breakeven per trip distance for trucks, in a McKinsey report on mobility transitions (see https://www.mckinsey.com/industries/aut ... 21787ac6d6):
Hydrogen cars or battery electric vehicles—why not both?
Battery-powered electric vehicles (EVs) are not the only alternative to cars with internal-combustion engines. Vehicles powered by hydrogen fuel cells have already begun trickling into select markets across Asia, Europe, and North America. While significant technical and infrastructure challenges remain, hydrogen offers several advantages over batteries. For starters, hydrogen vehicles fuel up relatively quickly—about 15 times faster than battery-powered EVs that use so-called fast-charging technology. Hydrogen refueling is also half as capital intensive as EV fast charging and requires about ten times less space (exhibit). In addition, EV fast-charger stations next to highways can easily require several power lines carrying multiple megawatts of electricity to cover peak load, but more flexible sources of renewable energy can power hydrogen fuel cells. And while battery-powered vehicles have significant consequences for natural resources—particularly cobalt, nickel, and lithium—hydrogen is the most common element in the universe.
Producing hydrogen, however, is costly, and at present fuel-cell vehicles are less commercially viable than EVs in most use cases. But heavier vehicles require heavier batteries; and the heavier the payload and the longer the range, the greater the opportunity for hydrogen power. A hydrogen-powered 40-ton semitruck, for example, when produced at scale, draws even with a battery-powered truck in system costs at slightly more than 100 kilometers of operation and allows for approximately three tons more payload as well. All this suggests that hydrogen vehicles and EVs could become complements in an increasingly decarbonized future. . . .
