A system and a method for filling a tank are provided. The tank filling system includes tanks that are filled with predetermined fluid and a manifold that is coupled to each of the plurality of tanks in a communication manner. A first flow passage is connected to a first inlet of the manifold to supply the fluid to be filled into the plurality of tanks to the manifold and a second flow passage is connected to a second inlet of the manifold spaced apart from the first inlet of the manifold by a predetermined distance to supply the fluid to be filled into the plurality of tanks to the manifold. A controller opens and closes the first flow passage and the second flow passage.

A multi-vessel fluid storage and delivery system is disclosed which is particularly useful in systems having internal combustion engines which use gaseous fuels. The system can deliver gaseous fluids at higher flow rates than that which can be reliably achieved by vapor pressure building circuits alone, and that keeps pressure inside the storage vessel lower so that it reduces fueling time and allows for quick starts thereafter. The system is designed to store gaseous fluid in liquefied form in a plurality of storage vessels including a primary storage vessel fluidly connected to a pump apparatus and one or more server vessels which together with a control system efficiently stores a liquefied gaseous fluid and quickly delivers the fluid as a gas to an end user even when high flow rates are required. The system controls operation of the pump apparatus as a function of the measured fluid pressure, and controls the fluid pressure in a supply line according to predetermined pressure values based upon predetermined system operating conditions.

The method for managing the supply of hydrogen to moving vehicles (1) from hydrogen distributed by distribution stations (7) comprises at least the following steps: a) collecting, by at least two sensors (2, 3) on board a vehicle (1), at least two parameters relating to the vehicle (1) during its movement, including at least the location of the vehicle, b) transmitting these parameters to a control module (5), c) collecting, by at least one sensor (12), at least one parameter relating to the hydrogen available in a distribution station (7), d) transmitting this parameter to the control module (5), e) identifying at least one hydrogen distribution station (7) while the vehicle (1) is moving, f) informing the user of the vehicle (1) of the available hydrogen distribution stations (7) and of the hydrogen supply conditions in the identified distribution stations.

The present invention relates to a curve-combined square pressure tank with which curves are combined so as to maintain internal high pressure, improve space efficiency, and reduce the weight thereof, and to a pressure tank, in which planes and curves are combined, formed by connecting flat plate members and curved members, having a plurality of aligned tension members for connecting the flat plate members facing each other, and having stress buffer parts formed at connection parts of the flat plate members and the curved members so as to enable internal pressure to be maintained.
