Abstract
A method for dispensing a compressed gas for reducing the amount of residual gas in dispensing station storage vessels before refilling is required. The method comprises transferring compressed gas into receiving vessels in a first series of fill-ups where each of the receiving vessels receive compressed gas from a first mobile storage device and subsequently from a second mobile storage device, transporting the first mobile storage device to a refilling station after the first mobile storage device has been depleted to a selected depletion level, refilling the first mobile storage device at the refilling station, and transferring compressed gas into receiving vessels in a second series of fill-ups where each of the receiving vessels receive compressed gas from the second mobile storage device and one or more of the first mobile storage device after refilling and a third mobile storage device.
