Validating of a fill control formula used by a hydrogen dispenser for dispensing hydrogen is described. Template data of the hydrogen dispenser related to dispensing of hydrogen by the hydrogen dispenser over a period of time is received, as well as static parameter values. One or more fill operations for dispensing hydrogen to one or more hydrogen fuel tanks may be simulated based on the template data and static parameters, as well as based on the fill control formula utilized in the hydrogen dispenser. A comparison of one or more fill operation parameter values calculated by simulating the one or more fill operations and one or more values of one or more similar fill operation parameters in the template data may be output on a user interface.

The present disclosure provides systems and methods for refilling fluid containers. A fluid container may include a bottle and a valve assembly. The valve assembly may include two valves and be configured to engage with the bottle and a filling head or dispensing head. A system is configured to provide pressurized fluid to the refillable container, monitor filling, determine when to stop filling, and determine how much fluid was provided. The valve assembly may include a float mechanism coupled to one of the valves of the valve assembly to ensure fluid flow is stopped when the fluid container is full. The fluid, which can include carbon dioxide, is stored in a storage tank. A flow system provides the fluid to a filling head, which engages with the fluid container. The flow system includes a transfer pump, valves, and sensors configured to provide the fluid to the filling head.

A pressure vessel for storing hydrogen is described. The pressure vessel includes at least one chamber to store hydrogen atoms. The pressure vessel also includes a mycelium structure within the at least one chamber. The mycelium structure has a surface area of at least 800 m.sup.2/m.sup.3. At least some of the hydrogen atoms are attached to the mycelium structure at a pressure greater than ambient pressure. Methods of storing hydrogen and methods of constructing a hydrogen storage tank are also described.

Device and method for filling pressurized-gas tanks, comprising a fluid transfer circuit provided with an upstream end intended to be connected to a source of gas and at least two parallel downstream ends intended to be connected to distinct tanks that are to be filled, the transfer circuit comprising a temperature regulating member for regulating the temperature of the gas transferred from the source towards the downstream ends, the gas temperature regulating member being positioned in the transfer circuit upstream of the at least two downstream ends, which means to say that the gas temperature regulating member is common to the at least two downstream ends, characterized in that the at least two downstream ends of the circuit each comprise a respective control member for controlling the flow rate and/or the pressure of the transferred gas and configured to control the flow rate and/or the pressure in each of the downstream ends independently.

Fuel gas distribution method where residual fuel gas in a mobile fuel gas storage vessel being transported by a transport vehicle is transferred from the mobile fuel gas storage vessel to the transport vehicle for generating power. The fuel gas may be natural gas or hydrogen. The transport vehicle may be a fuel cell vehicle.

A sealed and thermally insulating wall for a tank for storing fluid includes a heat-insulating panel and a sealing plate. The inner face of the heat-insulating panel has a stress-relieving slot.

An inspection apparatus A for a hydrogen gas dispenser includes a receiving-side gas flowing unit 1 including a receptacle 11 configured to be connected to a nozzle C1 of a hydrogen gas dispenser C and an inspection unit including a rate-of-pressure-rise inspection unit 2 configured to measure a rate of pressure rise of hydrogen gas from the hydrogen gas dispenser C and a dispensed-amount inspection unit 3 configured to measure a dispensed amount of the hydrogen gas. The inspection apparatus A for a hydrogen gas dispenser is capable of measuring a dispensed amount and a rate of pressure rise of the hydrogen gas dispenser.

A system for managing liquid supply is provided. The system includes an air pressure adjustor, a first liquid container, a second liquid container, a first tube, a second tube, an inlet sensor, and an outlet sensor. The first liquid container includes a liquid. The second liquid container includes an inlet and an outlet. The first tube is configured to be connected between the first liquid container and the inlet. The second tube is configured to be connected between the outlet and the air pressure adjustor. The inlet sensor is disposed on the first tube and for detecting the liquid flowing into the inlet. The outlet sensor is disposed on the second tube and for detecting the liquid flowing out from the outlet.
