Polymeric liner based gas cylinder with reduced permeability

A system for powering a vehicle, the system comprising:

• an engine or power generation system configured to be powered by a fuel;
• one or more axles coupled to the engine or power generation system and configured to translate power generated from the engine or power generation system to a plurality of wheels to move the vehicle;
• a housing configured to store a cylinder configured to store the fuel to be used by the engine or power generation system,
• wherein the cylinder comprises a first end portion, a second end portion, a central body forming an enclosed cavity for storing pressurized gas, a reinforcement structure disposed over the central body, and a metal foil interposed between the reinforcement structure and central body, the metal foil configured to reduce permeation of contents of the cylinder.

A vehicle system comprising:

• an engine or power generation system configured to be powered by a pressurized gas;
• an internal pressure enclosure comprising:
• a first end portion;
• a second end portion;
• 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 internal pressure enclosure, and
• the central body between the inner surface and the outer surface being a continuous expanse of a homogenous material;
• a reinforcement structure disposed over the central body;
• 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 internal pressure enclosure;
• and
• a housing configured to receive the internal pressure enclosure.
