1. An apparatus for storing pressurized gas, the apparatus comprising:
an enclosure comprising:
a first end portion;
a second end portion;
a first neck located in the first end portion, the first neck configured to provide an inlet and/or outlet for the pressurized gas;
a central body having a first end coupled with the first end portion and a second end coupled with the second end portion, the central body further having an outer surface and an inner surface disposed between the first end and the second end,
the first end portion, the second end portion, and the central body forming an enclosed cavity for storing the pressurized gas wherein the inner surface of the central body forms at least a portion of an innermost surface of the enclosure;
a reinforcement structure disposed over the central body; and
a barrier structure interposed between the reinforcement structure and the outer surface of the central body, the barrier structure configured to reduce permeation of contents of the enclosure,
wherein the barrier structure comprises a multilayer tape wound circumferentially about the outer surface of the central body, the multilayer tape comprising a first polymer layer having an inner surface and an outer surface, a metal foil layer, a second polymer layer having an inner surface and an outer surface, and an adhesive layer, the adhesive layer securing a portion of the inner surface of the second polymer layer to the outer surface of the central body, and the metal foil layer being disposed between the inner surface of the first polymer layer and the outer surface of the second polymer layer,
wherein the multilayer tape comprises one or more elongate strips each comprising a first elongate lateral edge and a second elongate lateral edge, wherein the first polymer layer, the metal foil layer, the second polymer layer, and the adhesive layer each extend from the first elongate lateral edge to the second elongate lateral edge, and
wherein each of the one or more elongate strips are wound circumferentially about the outer surface of the central body in an overlapping configuration that positions the first elongate lateral edge of a first winding longitudinally between the first and second elongate lateral edges of a neighboring winding, with the adhesive layer securing a portion of the inner surface of the second polymer layer of the first winding to the outer surface of the first polymer layer of the neighboring winding.
