Abstract: A method for recharging a high pressure gas storage container unit comprises transporting a recharge gas container containing a fluid at a cryogenic temperature and low pressure; heating the fluid in the recharge gas container and the fluid expelled from the recharge gas container to ambient temperature; and filling the high pressure gas storage container with the heated fluid as a pressurized gas. A system for recharging gas at a high pressure level comprises a recharge gas container unit comprising a means for containing cryogenic liquid and a first means for heating the liquid, the first heating means disposed near an outlet portion of the containing means; a second means for heating operatively connected to the recharge gas container unit during recharge; and a high pressure storage container unit comprising means for storing gas at a high pressure, said storing means operatively connected to the second means for heating during recharge.
