Rapid fill compressed gas storage tank

A method for rapidly filling a compressed gas storage tank with a moderated temperature rise, comprising:

• a. providing a gas storage tank, wherein the gas storage tank has an inner surface, an outer surface, a proximal end, a distal end, and a midpoint between the proximal end and the distal end;
• b. providing a stored gas, wherein the stored gas is contained inside the gas storage tank;
• c. providing a feed gas;
• d. providing a Coanda nozzle to inject the feed gas into the gas storage tank, wherein the Coanda nozzle is effectively connected to the proximal end of the gas storage tank;
• e. injecting the feed gas into the gas storage tank through the Coanda nozzle;
• f. using the Coanda nozzle to direct the feed gas along a curved surface of the Coanda nozzle, wherein a Coanda effect causes the feed gas to flow along the inner surface of the gas storage tank;
• g. providing a gas mixing zone at the proximal end of the gas storage tank that is in fluid communication with the feed gas;
• h. entraining the stored gas with the feed gas in the gas mixing zone to form a mixed gas using inertia of the feed gas that is flowing under influence of the Coanda effect to direct the mixed gas to flow along the inner surface of the gas storage tank;
• i. transferring heat from the mixed gas to the gas storage tank;
• j. providing a phase change material along the inner surface of the gas storage tank;
• k. transferring heat from the flowing gas to the phase change material;
• l. providing an inner liner and providing a gap, wherein the inner liner is positioned inside the gas storage tank such that it forms the gap between the inner surface of the gas storage tank and the inner liner, wherein the mixed gas flows through the gap;
• and,
• wherein providing the inner liner provides the gap for the mixed gas to flow through that is continuous from the proximal end to at least 15% of a length from the proximal end to the distal end of the gas storage tank.
