Method for filling a tank with liquid hydrogen and associated storage device

Abstract

The present disclosure relates to a method for filling a tank (9) with liquid hydrogen, the tank comprising: o a cavity (11) delimited by an internal wall (2), the cavity (11) being configured to receive liquid hydrogen at a temperature (TH) lower than an ambient temperature (TA) of the air around the tank (9), o a first wall (5) disposed around the internal wall (2) and delimiting an empty space (8) between the internal wall and the first wall (5), the method comprising a step of circulating liquid nitrogen in at least one pipe (13) located outside the cavity (11) and in contact with the internal wall (2), the circulation step starting before a step of filling the tank (9) with liquid hydrogen, the liquid nitrogen producing an internal wall temperature (TPI) greater than or equal to the temperature of the liquid hydrogen (TH) and lower than the ambient temperature (TA).
