Abstract
A H2 defueling system for automating defueling of a hydrogen tank is disclosed. The H2 defueling system comprises: a hydrogen storage tank containing hydrogen; a plurality of electronic valves configured for regulating hydrogen discharge of hydrogen from the hydrogen tank; at least one pressure sensor and at least one temperature sensor; a hydraulic circuit interconnecting the hydrogen tank, the plurality of electronic valves, the at least one pressure sensor and the at least one temperature sensor; and a control unit configured to: receive input from the at least one pressure sensor and the at least one temperature sensor; automatically adjust the flow rate of gaseous hydrogen from the storage tanks based on the input from the sensors to maintain the gaseous hydrogen within pressure limits; modulate operations of the plurality of electronic valves to control hydrogen discharge to control the flow of hydrogen from the hydrogen tank.
