Method for filling a storage vessel with liquefied gas by means of a tank of liquefied gas, the method comprising a step of transferring liquefied gas from the tank into the storage vessel by means of a pressure differential, wherein the storage vessel prior to the transfer step has an internal pressure higher than the internal pressure of the tank, the method comprising, prior to the transfer step, a step of placing the tank and the storage vessel in fluidic communication in order to ensure a drop in the pressure in the storage vessel to the benefit of the tank and a step of increasing the pressure in the tank using a pressurizing device.

A gas supply system for providing high pressure (HP) gas to a low pressure (LP) gas destination, having a primary HP gas unit and a reserve HP gas unit, which provide regulated lower-pressure gas to a supply manifold, and an LP destination regulator that provides an LP regulated gas supply to a consumption subsystem. A one-way flow valve in fluid communication from the primary HP gas unit to the reserve HP gas unit, ensures that the reserve HP gas unit remains substantially full, even after numerous cycles of depletion and replacement of the primary HP gas unit, during which the HP supply is provided by the reserve HP gas unit, which helps to avoid the risk that the reserve tank pressure and supply might mistakenly, unexpectedly or unintentionally be depleted.

A type IV conformable pressure vessel has improved mechanical coupling between an outer composite shell and a boss.

In addition, the boss has a shank extending between the liner and the outer composite shell. The shank includes a plurality of spikes projecting radially away from the boss. The outer composite shell of resin and fiber surrounds an outer periphery of the liner and an outer periphery of the shank. The spikes are embedded into the outer composite shell to mechanically fasten the outer composite shell to the boss.

A cryogenic storage system basically includes a first cryogenic storage tank, a second cryogenic storage tank, a fluid transfer line and a cryogenic containment structure. The first cryogenic storage tank has a first predetermined capacity of liquefied gas. The second cryogenic storage tank has a penetration free bottom and a second predetermined capacity of the liquefied gas that is larger than the first predetermined capacity of the first cryogenic storage tank. The fluid transfer line is fluidly connected between the first cryogenic storage tank and the second cryogenic storage tank. The heat exchanger converts liquid exiting the first cryogenic storage tank to a higher pressure gas that is used as a motive force to move liquidized gas out of the second cryogenic storage.
