Disclosed are gas cylinder assemblies for containing pressurized gas. The gas cylinder assembly has a polymeric liner and a low-permeability barrier layer. The polymeric liner a first end portion, a second end portion and a central body. The central body comprises an outer surface and an inner surface disposed between the first end and the second end. The gas cylinder assembly comprises a reinforcement structure wound over the central body. The gas cylinder assembly further comprises a metal foil interposed between the reinforcement structure and central body. The metal foil is configured to reduce permeation of contents of the polymeric liner.

A system for powering a vehicle is provided. The system can include an engine or power generation system to be powered by a fuel and a housing. The housing can be configured to couple to one or more frame rails of the vehicle, receive and protect a cylinder configured to store the fuel to be used by the engine or power generation system. The housing can have one or more access panels allowing access to an interior of the housing. The cylinder can include 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 can be configured to reduce permeation of contents of the cylinder.

This disclosure describes an apparatus having a valve and an elongated shape memory alloy element. The valve has a lever in a first position, whereby the valve is closed. The elongated shape memory alloy element has a first end connected to the lever. The shape memory alloy element has been strained to have a first length, wherein exposure of at least a portion of the shape memory alloy element to a temperature at or exceeding its austenite transformation temperature causes the shape memory alloy element to shorten to a second length, the second length being less than the first length, thereby causing the first end of the shape memory alloy element to pull the lever to a second position, whereby the valve is opened.
