A method and system for recycling permeated gas is disclosed. A container encapsulating a pressure vessel defines a containment volume. Gas permeating through the pressure vessel is captured in the containment volume. When a sensor detects a threshold level of permeated gas captured within the containment volume, a control module sends a command to open a purge valve. The open purge valve allows permeated gas captured within the containment volume to be supplied to an engine, a repressurization unit, or a secondary container.
