More Information
Summary:The invention relates to a method of detecting a leakage in a hydrogen refuelling, the method comprising establishing at a first and a second time a first and a second representation of at least one fluid parameter associated with hydrogen stored in at least one hydrogen storage tank of the hydrogen refuelling station, determining a relative difference between the first and second representation of the at least one fluid parameter, and comparing the relative difference with a threshold difference to detect a leakage. The invention further relates to a hydrogen refuelling station comprising a hydrogen storage module comprising a plurality of hydrogen storage tanks, a hydrogen station module comprising a compressor, and a dispensing module comprising at least one dispensing nozzle, the hydrogen refuelling station comprising at least one controller arranged to control the hydrogen refuelling station and arranged to detect a leakage using the beforementioned method.
