A hydrogen storage and supply device comprises an internal reservoir which internally delimits a storage volume and an external reservoir, wherein an intermediate space separates the internal reservoir from the external reservoir. A heat exchanger has a hydrogen circulation side provided with a hydrogen inlet; and a conduit supplies the heat exchanger with hydrogen. An external conduit is received in the intermediate space. The external conduit has: an intermediate volume; an upstream section having an upstream upper end passing through the internal reservoir and fluidically connected to the storage volume, and an upstream lower end connected to the intermediate volume; and a downstream section connected to the intermediate volume and having a downstream upper end connected to the hydrogen inlet. The downstream upper end is located at a first elevation, the upstream upper end is located at a second elevation, and the intermediate volume is located at a third elevation, lower than the first and second elevations.

A storage vessel for storing a cryogen, having an inner vessel for receiving the cryogen, an outer vessel which surrounds the inner vessel, and a heating device, which is at least partially arranged within the inner vessel, for introducing heat into the cryogen, wherein the heating device has a heating element for generating the heat and an outer casing which fluid-tightly surrounds an interior space of the heating device, wherein the heating element is accommodated within the interior space, and wherein the heating element has a heating wire which is embedded in a metal oxide which is encapsulated by a casing accommodated within the interior space.

A model-based fault detection device for a liquid hydrogen refueling system using a cumulative sum method includes a memory that stores instructions, and a processor configured to, by executing the instructions, obtain process variables inside a liquid hydrogen storage system based on a simulation model for the liquid hydrogen storage system, obtain normal scenario data and fault scenario data of the process variables by using a steady-state model and a dynamic state model for the liquid hydrogen storage system, calculate an upper end cumulative sum index C.sub.i.sup.+ and a lower end cumulative sum index C.sub.i.sup. by applying a cumulative sum (CUSUM) control method to deviation data corresponding to a difference between the normal scenario data and the fault scenario data, and detect whether the liquid hydrogen storage system is faulty by comparing the upper end cumulative sum index C.sub.i.sup.+ and the lower end cumulative sum index .sub.C.sup. i with a threshold.

An injector for a gas reservoir, the injector having a duct designed to fluidically connect a filling station and the reservoir to be filled, the duct extending along a main axis and having an inlet orifice designed to receive a pressurized gas flow coming from the filling station and an outlet orifice designed to convey said flow towards the reservoir to be filled, also including a mobile member disposed inside the duct and designed to move relative to the outlet orifice, between a first extreme position in which the mobile member provides the outlet orifice with a minimum passage section, and a second extreme position in which the mobile member provides the outlet orifice with a maximum passage section.

A method for storing fluids and waste underground in a subterranean zone and one or more fractures created with a fracture and seal process. This will be useful for oil and gas fields, depleted oil or gas wells, abandoned oil or gas wells, industrial plants, food processing plants, or other fluid or waste storage operations.

A method for controlling the operating pressure of a liquid carbon dioxide receiving facility is disclosed, the method comprising unloading liquid carbon dioxide from a transport vessel to the liquid carbon dioxide receiving facility, storing the liquid carbon dioxide in a temporary storage at the liquid carbon dioxide receiving facility, pumping the liquid carbon dioxide from the temporary storage to permanent geologic storage or external use, and managing pressure in the temporary storage using at least some of the carbon dioxide liquid phase.

A service providing mobile unit comprising the frame 2, movement-use wheels 4, 5 provided at the bottom part of the frame 2, hydrogen storage tank insert parts 10 formed inside the frame 2, and the fuel cell 40 arranged in the frame 2. A service for supplying hydrogen to the fuel cell 40 from the hydrogen storage tank 20 inserted in the hydrogen storage tank insert part 10, a service for lending out the hydrogen storage tank 20 inserted in the hydrogen storage tank insert part 10, a service for returning a used hydrogen storage tank 20 to the hydrogen storage tank insert part 10, and a service for storing the hydrogen storage tank 20 inserted into the hydrogen storage tank insert part 10 are provided.

A gas supply system supplies gas to an appliance consuming high-pressure gas of a floating structure including at least one tank. The gas supply system includes at least one first supply circuit for supplying the high-pressure consumer appliance, including a first heat exchanger, a second heat exchanger, and a pump. The gas supply system also includes a pre-cooling system for pre-cooling the first heat exchanger to take gas in the liquid state from the tank. The pre-cooling system includes a pre-cooling line and a control valve for controlling the circulation of gas within the pre-cooling line.

The gas supply device disclosed in the present specification includes a cover that shuts off the periphery of the main stop valve and the connector of the gas cartridge from the outside air, and a removal device that removes impurities from the inner space of the cover in a state where the connector and the main stop valve are not connected. The controller of the gas supply device connects the main stop valve and the connector when impurities are removed from the inner space by the removal device, and opens the main stop valve. The gas supply device disclosed herein shuts off the periphery of the main stop valve and the connector from the outside air and removes impurities from the periphery of the main stop valve. Therefore, contamination of the gas supply device with impurities can be suppressed.

A floating LNG storage barge with one or more LNG tanks provides mobile storage for LNG, by obtaining LNG from one or more LNG ocean transport vessels while the LNG storage barge is moored to a land-based jetty, transferring LNG to one or more land transfer trucks, pipelines or railroad tankers using an LNG distribution manifold and flexible hoses between the distribution manifold and the trucks via pumps or pressure differential between the LNG storage barge with the potential for LNG processing adaptive capacity.
