1. A method of providing gaseous hydrogen to a vehicle comprising: a. storing a liquid hydrogen source in a feed vessel at a temperature of less than 30 K; b. passing a portion of the liquid hydrogen in the feed vessel to a first flash drum; c. passing a portion of the liquid hydrogen in the feed vessel to a second flash drum; d. providing sufficient heat to the first flash drum to convert at least a portion of the liquid hydrogen to gaseous hydrogen; e. passing the gaseous hydrogen from the first flash drum to a dispenser; f. when the pressure of the gaseous hydrogen from the first flash drum drops to below a first pressure, providing sufficient heat to the second flash drum filled with liquid hydrogen to convert at least a portion of the liquid hydrogen to gaseous hydrogen to provide gaseous hydrogen at or above the first pressure; g. passing the gaseous hydrogen from the second flash drum to the dispenser; and h. passing the gaseous hydrogen from the dispenser to the vehicle at a pressure of greater than 300 bar wherein no compression apparatus is used.
