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.

Disclosed herein is a gigavault facility for the storage of liquids and gases. The facility comprises a plurality of tubular composites which can provide continuous monitoring for safety and durability, and which can flexibly accommodate a variety of different media. Also disclosed are methods for the storage of media, including liquids and gases.

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 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.

Systems for detecting gas leaks in gas systems are provided. The systems can include: at least one gas cylinder; at least one valve assembly operatively engaged with the gas cylinder; and a purge conduit assembly operatively engaged with an interior portion of the valve assembly. Methods for detecting gas cylinder leaks in a gas system are provided. The methods can include providing purge gas through an interior portion of a valve assembly operably coupled to a gas cylinder. The system is enclosed within a cabinet; the method can include providing positive pressure within the cabinet sufficient to provide flow through the purge conduit assembly. Ultra-high purity gas cylinder valve assemblies are provided. The assemblies can include: a diaphragm separating an upper and lower portion of the valve assembly; a purge gas input conduit in fluid communication with the upper portion; and a purge gas outlet conduit in fluid communication with the upper portion.

Proposed is a hydrogen management system in which location information, pressure information, temperature information, collision information, hydrogen concentration information, and flow rate information are transmitted from sensors mounted in a manifold of each of a plurality of tube trailers (T1, T2, . . . ), and the hydrogen consumption amount, the remaining hydrogen amount, the number of users, etc. are transmitted from the plurality of hydrogen charging stations (S1, S2, . . . ) so that current hydrogen storage and demand amounts are predicted, thereby managing an entire hydrogen cycle, including hydrogen production, in an integrated manner.

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.

Systems, apparatus, articles of manufacture, and methods are disclosed to detect obstructed valves in pressure relief systems. An example pressure relief valve includes an inlet port to be selectively fluidly coupled to a pressure vessel via a first shutoff valve, an exhaust port fluidly coupled to the inlet port via a valve, the valve to fluidly couple the inlet port and the exhaust port while a fluid pressure within the inlet port exceeds a threshold value, a first pressure sensor to detect a fluid pressure within the inlet port, a second pressure sensor to detect a differential fluid pressure between the exhaust port and the inlet port, and a data transmitter to transmit pressure data associated with the fluid pressures detected by the pressure sensors to a computing device.

A connection space for a hydrogen supply arrangement, having an inner region surrounded by the connection space for receiving components of the hydrogen supply arrangement, an inert gas supply device for flushing the inner region with an inert gas, and an exhaust gas system for discharging the inert gas from the inner region, wherein the inert gas supply device is designed to continuously supply the inert gas to the connection space and/or to maintain a constant inert gas pressure in the connection space.

A composite hydrogen storage tank for storing liquid hydrogen incudes a multilayer composite wall. The multilayer composite wall defines a chamber and includes an inner composite layer, an outer composite layer, and a plurality of insulating layers between the inner composite layer and the outer composite layer. A hydrogen barrier layer is formed on an inner surface of the inner composite layer. Each of the inner composite layer and the outer composite layer including a plurality of reinforcing fiber tows surrounded by a matrix. The outer composite layer forms an exterior of the composite hydrogen storage tank.

A liquid cryogen dosing head has a liquid cryogen reservoir in communication with a dosing outlet, a dosing valve stem having a lower, distal end configured to selectively open and close the dosing outlet, and an electromagnetic actuator attached to an upper end of the dosing valve stem above the liquid cryogen reservoir and operable to move the dosing valve stem to open and close the dosing outlet. The electromagnetic actuator is disposed above the liquid cryogen reservoir and the dosing valve stem extends through the liquid cryogen reservoir, preferably concentrically, to open and close the dosing outlet by blocking an orifice of the dosing outlet.
