A storage tank includes a frame, tank assembly, and scrubber system. The tank assembly including a vessel supported by the frame and having a first end, a second end, and a sidewall extending from the first end to the second end. The vessel further has a top, a bottom, at least one side, an internal surface, and an outlet fluidly coupled with the bottom. A scrubber tank is supported by the frame and fluidly connected to the a top of the vessel to receive vapors from the vessel in a way that when a vapor absorption material is disposed in the scrubber tank, the vapors pass into the vapor absorption material.

A control conduit for liquid hydrogen offloading is configured to couple a controller of a liquid hydrogen offload system to a liquid hydrogen tanker. The control conduit includes a control line and a gas detector. The control line is configured to transmit a control signal from the controller to the liquid hydrogen tanker. The gas detector is configured to detect hydrogen gas and provide a gas detector signal to the controller. The gas detector is secured to the control line at a predetermined distance from a tanker connection end of the control line.

A compressed gas storage system that includes a pressure vessel. The pressure vessel includes a first vessel portion and a second vessel portion in fluid communication with the first vessel portion. The pressure vessel includes a third vessel portion in fluid communication with the second vessel portion. The compressed gas storage system includes a first valve positioned between the first vessel portion and the second vessel portion and a second valve positioned between the second vessel portion and the third vessel portion. The first valve allows and impedes fluid flow between the first and the second vessel portions. The second valve allows and impedes fluid flow between the second and the third vessel portions.

Methods and manufactures disclosed herein generally relate to a cannular composite (ITC) structure composed of multiple layers of sealing, reinforcement, sensing, protection, and interspatial injected materials.

A filling station comprises a filling device for an automated filling of a gas bottle inserted in the filling station and a filling device for refueling a motor vehicle, wherein the filling device for an automated filling of a gas bottle inserted in the filling station is arranged adjacent to the filling device for refueling a motor vehicle.

An exemplary fuel cell ship is a fuel cell ship for propelling a hull by using electric power supplied by a fuel cell that generates electric power through an electrochemical reaction of fuel, and includes at least one compartment including an emission source of the fuel, and a vent pipe through which the fuel in the compartment is released to outside of the hull. A release port of the vent pipe is located at a position higher than a cabin or a bridge provided on the hull.

A container includes one or more hollow shell assemblies, each assembly having a first hollow shell including a first inner surface to cover a portion of a pressure vessel (PV) and a second hollow shell including a second inner surface attachable to the first hollow shell. The first and/or second hollow shells may include a fiber layer that may be at least partially impregnated with resin, and an energy dissipating material that is substantially concentric with the inner surfaces of the respective shells. The first and second hollow shells are attachable to one another to define a volume for at least partially enclosing the PV, and may be overwrapped via filament winding.

A method of detecting a leakage in a hydrogen refueling including establishing at a first and a second time a first and a second representation of at least one fluid parameter associated with hydrogen stored in at least one hydrogen storage tank of the hydrogen refuelling station, determining a relative difference between the first and second representation of the at least one fluid parameter, and comparing the relative difference with a threshold difference to detect a leakage, where a hydrogen refuelling station is provided including a hydrogen storage module comprising with a plurality of hydrogen storage tanks, a hydrogen station module having a compressor, and a dispensing module with at least one dispensing nozzle, the hydrogen refuelling station including at least one controller arranged to control the hydrogen refuelling station and arranged to detect a leakage using the beforementioned method.

A gas filling apparatus with excellent filling efficiency through a downsized gas pipe cooling section. A gas filling apparatus 1 of the present disclosure includes; a main unit 2 having a filling mechanism for transporting a gas from a gas supply source through a primary pipe 71 while measuring a flow rate of the gas and a gas pipe cooling section 41 for cooling a gas pipe in which a gas from the filling mechanism is introduced; and a hose unit 3 having a filling hose 34 connected to a secondary pipe 72 lead from the gas pipe cooling section and a gas filling nozzle attached to an end of the filling hose, wherein the gas pipe cooling section is made of copper alloy. The pipe cooling section can be disposed at a connecting portion between the secondary pipe and the filling hose, and plurality of the filling mechanisms can be mounted, and to each filling mechanism is independently mounted the gas pipe cooling section. The gas pipe cooling section can be accommodated in a vessel 42 with vacuum insulation structure, and to the vessel is connected a pipe 44 for communicating a vacuum portion 42a of the vessel with a diffusion pipe through a safety valve 43.

An underground storage tank maintenance system includes a system of monitors to determine pressure and humidity in the system. Inert gas may be supplied into the ullage of the tank. The inert gas may first pass through an interstitial space as between the primary storage and secondary containment, and then passed into ullage to capture contaminants on the way out of the vent to atmosphere. The system and method prevent hydrocarbons exiting to atmosphere. Humidity sensors may be set along vent to determine water contamination and trigger drying cycles. Pressure readings help identify system leaks.
