Abstract
The present invention provides a metal-lined composite gas storage device comprising a phase-change material coated on the exterior surface of a metallic liner. The presence of the phase-change material on the exterior surface of the metal liner reduces the temperature change within the interior of the metal liner during a gas filling process compared to a similar vessel that does not have a phase-change material coating, thereby allowing a significantly greater amount of gas to be filled at a given pressure.
Claims17
A metal-lined composite gas storage device configured for storing a gas under high pressure, said metal-lined composite gas storage device comprising:
- a metallic liner;
- a phase-change material coated on the exterior surface of said metallic liner;
- and
- a composite material encapsulating substantially all of the exterior surface of said phase-change material coated metallic-liner,
- wherein the presence of said phase-change material reduces the temperature change within the interior of said metallic liner during a gas filling process.
A method for increasing the amount of gas filled in a metal-lined composite gas storage device during a gas filling process, said method comprising placing a sufficient amount of phase-change material between a metallic-liner and the composite material encapsulating said metallic-liner such that the presence of said phase-change material between said metallic-liner and said composite material substantially reduces a temperature increase during a gas filling process thereby allowing said metal-lined composite gas storage device to be filled with a higher amount of gas during the gas filling process compared to a similar metal-lined composite gas storage device in the absence of said phase-change material.
