A liquefied gas storage tank according to an embodiment of the present invention may comprise: a tank unit in which liquefied gas is stored; an inner box unit disposed inside the tank unit and installed at the bottom portion of the tank unit; and a pump unit that has an inlet pipe part formed to pass through a lower wall portion of the inner box unit and communicate with the inside of the inner box unit, and suctions the liquefied gas stored in the tank unit through the inlet pipe part, thereby supplying the liquefied gas to the outside.

Hydrogen discharge system for a truck and truck comprising such system The invention concerns a hydrogen discharge system (14) for a truck, this system comprising a pipe (16) provided with at least one discharge opening (162), a deflector (18), that is rotatably mounted with respect to the pipe and that includes a vent, for venting hydrogen exiting through the discharge opening. The system further includes a balancing weight (22) secured to the deflector (18), so as to maintain the deflector in a configuration wherein the vent is facing upwards with respect to the ground, in order to always discharge hydrogen upwards relative to the ground.

Example integrated cryogenic hydrogen tank systems and methods for operating the same are disclosed herein. An example system comprises a first cryogenic tank coupled to a second cryogenic tank via a liquid hydrogen (LH2) transfer flowline and a gaseous hydrogen (GH2) transfer flowline, the LH2 transfer flowline and the GH2 transfer flowline to maintain a fuel level and a vapor pressure across the system, the fuel level corresponding to a cryogenic liquid; an inlet port connected to one of the first cryogenic tank or the second cryogenic tank; an LH2 extraction flowline connected to at least one of the first or second cryogenic tanks to supply the cryogenic liquid to a fuel management system; and a pressure safety system coupled to at least one of the first or second cryogenic tanks via a GH2 extraction flowline.

An assembly is for filling a gas tank for a combustion engine from a gas-filled storage bottle via a filling device arranged between the tank and the storage bottle. The tank has at least one fill valve for liquefied gas, a pressure relief valve for gas in the gaseous state, and an extraction valve for liquefied gas. The filling device has a gas connection for the storage bottle and has a fill connection for the fill valve. For filling the tank, the fill valve is connected via the filling device to the storage bottle, such that, when the fill valve is open, liquefied gas flows from the storage bottle via the fill valve into the tank. During the inflow of liquefied gas, the pressure relief valve of the tank is at least intermittently open. A filling level gauge is provided for indicating a predefined filling level in the tank.
