Hydrogen refueling station and method for refueling a hydrogen vehicle

A hydrogen refueling station comprising:

• a hydrogen storage module comprising at least a first hydrogen storage tank
• a hydrogen station module comprising a compressor and a controller,
• a first dispensing module comprising a first dispensing nozzle connectable to a first vehicle and a first dispensing pressure detection means, and
• a second dispensing module comprising a second dispensing nozzle connectable to a second vehicle and a second dispensing pressure detection means,
• wherein a first supply line is fluidly connecting the hydrogen storage module to an inlet compressor line on a low-pressure side of the compressor via a first inlet compressor valve,
• wherein a compressor outlet line is fluidly connecting an outlet on a high-pressure side of the compressor to a dispensing line and thereby to the first dispensing module via a first output compressor valve and to a further dispensing line and thereby to the second dispensing module via a second output compressor valve,
• wherein a first cascade line is fluidly connecting the hydrogen storage module and the first dispenser module via a first cascade valve and thereby the first cascade line is configured for bypassing the compressor,
• wherein a second cascade line is fluidly connecting the hydrogen storage module and the second dispenser module via a third cascade valve and thereby the second cascade line is configured for bypassing the compressor,
• wherein the controller is configured for controlling valves (7a, 13a, 13b, 11a, 11b) and thereby a fluid path from the hydrogen storage module to the first dispensing module and to the second dispensing module,
• wherein a pressure detection means is configured for detecting a pressure in the compressor outlet line,
• wherein a backflow line is connecting the compressor outlet line to the first supply line via a bypass valve,
• wherein the controller is configured for controlling the bypass valve based on feedback from the pressure detection means, from the first dispensing pressure detection means or from the second dispensing pressure detection means to establish a required pressure in the compressor outlet line.
