Based upon their example "just about as fast as filling up a gasoline-powered car." Is not exactly accurate for a number of reasons.

On paper, it would be more like filling up and emptying 4 gasoline-powered cars. That's about 8x the process in the ideal case.

Other considerations would be the necessity for 8x as much storage in gas stations, 8x as many refilling trucks to supply and empty those stations, and above all, the development of a nationwide network of such infrastructure as pervasive as the existing fuel network.

This is even more dead on arrival than hydrogen.

Why would it need 8x the storage or trucks? They'd recharge the spent fluid on-site and re-use it.

You do understand that conventional gas pumps are legacy devices on which the UI dates back to the days when the gas was literally pumped by hand?

That they don't remotely approach maximum practical flow rate that can be produced by a pump, even a small one?

That there are quick connectors that can vastly exceed the flow rate of the current hand-held nozzle shoved into a hole?
