Abstract: This invention can provide a hydrogen refueling system capable to reduce waiting time for refueling H2 to vehicles. The system is designed and operated to acquire the residual pressure in the vehicle the that connects to the dispenser, then to calculate sufficient conditions to perform complete refueling of the connected vehicle (in particular minimum pressure in buffers), and then to start H2 transfer to the vehicle as soon as the conditions are met. Waiting time can be further reduced with minimum investment by having a H2 dispenser with two H2 refueling hoses which has only one H2 flow control valve and/or only one H2 cooling heat exchanger and/or only one H2 flow metering system.
