Abstract: A method for filling a tank with pressurized gaseous hydrogen from at least one source storage containing pressurized gaseous hydrogen at a first defined temperature and at a defined pressure higher than the pressure in the tank to be filled, in which hydrogen is transferred from the source storage to the tank by pressure balancing via a filling circuit having an upstream end linked to the source storage and a downstream end linked to the tank, and in which the at least one source storage exchanges heat with a member for heating the gas stored in the source storage, during at least a part of the transfer of hydrogen from the source storage to the tank, the gas contained in the source storage being heated to a second defined temperature that is higher than the first temperature.

Abstract: A boil-off gas processing system for reliably burning a boil-off gas. The system processes a boil-off gas produced from a liquid hydrogen tank which is built in a hydrogen fueled vehicle. The system includes a mixing device for introducing air into a discharge passage through which the boil-off gas from the liquid hydrogen tank passes and for mixing the air and the boil-off gas and outputting a mixed gas; a catalytic combustor for burning the mixed gas which was mixed by the mixing device, the catalytic combustor having an inlet through which the mixed gas is introduced and an outlet for discharging combustion gas; an electric heater provided at the inlet side of the catalytic combustor; and a control section for controlling energizing of the electric heater.
