Claim 0:
1. A hydrogen gas dispenser configured to receive hydrogen gas from a hydrogen gas supply and provide the hydrogen gas to a fuel tank of a vehicle during a fueling event, the hydrogen gas dispenser comprising:
at least one nozzle configured to engage with the fuel tank to dispense hydrogen gas to the fuel tank during the fueling event;
a variable-size valve comprising a valve stem that when rotated changes a size of the valve opening, the variable-size valve coupled to receive hydrogen gas from the hydrogen gas supply such that changing the size of the valve opening results in a change in a flow rate of hydrogen gas passing through the valve opening;
a direct drive servo motor coupled to the valve stem of the variable-size valve, the direct drive servo motor configured to rotate the valve stem to change the size of the valve opening, wherein one rotation of the direct drive servo motor results in one rotation of the valve stem; and
a dispenser controller coupled to the direct drive servo motor and configured to cause the direct drive servo motor to rotate to change the size of the valve opening to provide hydrogen gas at desired flow rates based on target pressures and/or target flow rates during the fueling event.
