> Regarding the costs of a fueling station, the hope is that as the technology is more mature, the costs will decrease substantially. The equipment isn't anywhere close to being mass produced the way it is for gas stations and BEV charging stations.
A good chunk of the costs involved in getting a H2 station running is regulation and licensing. You can't just store 500kg of pressurised hydrogen on any parking lot. You need permits and licenses and all that fun stuff. You also need to maintain it, actually bring the H2 to the station from somewhere etc.
An EV charging station is pretty much a fancy extension cord, you need a HV certified electrician, a backhoe and some cables along with the charger units. You don't need permits from anyone except maybe from the power company. Cost for a 22kW AC charger is maybe 1k per unit, HVDC units are 20-50k a pop, depending on the amount of power.
Wal-mart, for example, could have 40 350kW HVDC chargers (complete overkill btw) on their parking lot for the price of one H2 station, that can serve 2 cars every 5-20 minutes. Or they could electrify their whole parking lot with 22kW destination chargers and still have money left over.
Hydrogen will have its day, but there are WAY too many hurdles for it to cross before it becomes something regular people can have in their cars.
Hydrogen trucks for long haul trips, yes. Hydrogen powered cargo ships, yes. Hydrogen for renewable energy storage, yes.
If we want H2 to become a valid choice for normal family cars, someone needs to put up billions to get a proper refueling network up and running and keep it running. Which needs a reliable, cheap, source of hydrogen and a fleet of trucks.
Maybe a Hydrogen-Musk will appear some day? =)
