With the high flow we would have to fill the tank everyday. With the low flow, refueling would take several hours but the tank would hold enough fuel for several days driving. I guess that means high flow refueling, more friction in the flow, less fuel in the tank. Low flow refueling, less friction in the flow, more fuel in the tank.

I would guess a high rate of compression would generate significant heat limiting the amount delivered.

That may be true, I’m not sure. I thought it had to do with how fast the gas was flowing into the tank, higher flow rate, more friction, gas expands and fills the allowable space sooner. Lower flow rate, less friction, gas does not expand as much, allows for more of the gas to enter the tank. I could be wrong, but I did know that the longer time to fill allowed more fuel to be stored in the tank.
