Description

ABSTRACT:
In order to improve a method for filling a cryotank with liquid hydrogen, in which thermal energy is introduced into the liquid hydrogen by the transfer of the liquid hydrogen to the cryotank, such that the amount of gas which results during filling of a cryotank and is carried away via the gas return line is reduced to as great an extent as possible, preferably to zero, it is suggested that for filling hydrogen be used at a pressure and a temperature corresponding to an undercooled state of the liquid hydrogen.
