It is going to be difficult to make money with hydrogen filling stations; both liquid and compressed hydrogen come with huge challenges in terms of transportation and storage.
Petrol stations will not make much money on electricity if they install chargers, but they will sell a lot of food to customers waiting to charge, even "supercharging" is quite slow..
That sounds like one of those "alternative facts". After following the cite trail from Wikipedia, it was apparently something someone from the hydrogen car industry said at a conference. No further cite or info on what exactly they are counting in that figure.
Cost difference does seem counter-intuitive but not an expert. I also wonder if rather than transporting hydrogen around they could make it on site from piped water. Not sure if electrolysis of water has scale benefitsm of mass producing hydrogen then trucking around. That could reduce cost of transport... but then that would be much the same as electric anyway with the inevitable energy loss on conversion...
EV chargers are much cheaper to operate/install than gas pumps; and gas pumps should be less expensive than hydrogen filling stations, i.e. something does not add up here.
It's very expensive to keep hydrogen cool enough to stay liquid, but it's not exactly cheap to keep hydrogen compressed in massive tanks that always leak either. Moving it around is another problem, I find it extremely unlikely that this costs less to operate than electric infrastructure, which is static.
