A gas storage and delivery system periodically passes cryogenically stored gas 10 in discrete quantities via a buffer container 12, to a vapourisation tank 14. The buffering in the delivery systems permits the device to maintain a level of ready to use gas in the tank 14 between certain limits. The gas is tapped off for use in a gas usage device 16, which consumes gas for various purposes and may be such as a fuel cell, combustion engine, gas expander or the like. A heating system 40 - 50, may aide the vaporisation process in the vapourisation tank 14.
