A method for displaying a fill level of a pressure vessel includes measuring an actual fill level of the pressure vessel, calculating a displayable fill level based on the actual fill level, and displaying the displayable fill level via a display device. In the method, during refueling between a first filling point (FP1) and a second filling point (FP2), the displayable fill level is increased in relation to the actual fill level in accordance with a predefined characteristic curve.

A multi-walled storage tanks use pressure differences between walls/shells to maximize fluid mass storage for tank size by reducing or minimizing the distance between the outer most layers of a multi-layer storage device, and keeping the middle one(s), particularly the innermost space, as large as possible, while having shell walls of substantially the same material and thickness, with no wall being thicker than the inner shell wall.

A pressure vessel and a method for producing a pressure vessel are provided. The pressure vessel has a liner and a fiber-reinforced laminate, which surrounds the liner and has a first fiber layer and a second fiber layer, which are incorporated in a matrix material. The method includes: a) providing the liner for storing a fluid, having a cylindrical region and two cap regions at opposite ends of the cylindrical region, b) wrapping a fibrous material impregnated with matrix material around the liner at the cap regions and the cylindrical region to produce the first fiber layer, which is already permeated with matrix material, c) arranging the second fiber layer around the first fiber layer, wherein the second fiber layer is formed by at least one braided sleeve of dry fibers, and d) curing or consolidating the matrix material without supplying additional matrix material to produce the fiber-reinforced laminate.

A high pressure tank is provided with a reinforcement layer. The reinforcement layer is provided with an inner laminated section, an outer laminated section, and an intermediate laminated section. The inner laminated section includes a winding start of an impregnated fiber and is disposed radially inward. The outer laminated section includes a winding end of the impregnated fiber and is disposed radially outward. The intermediate laminated section is formed between the inner laminated section and the outer laminated section. First and second dome portions of a liner are respectively provided with first and second core materials between the inner laminated section and the outer laminated section.

A high-pressure tank includes a reinforcing layer and a liner having a gas-barrier property and disposed on an inner surface of the reinforcing layer. The reinforcing layer includes a cylindrical reinforcing pipe having a plurality of cylindrical pipe forming portions coupled together, and a pair of semispherical reinforcing domes, one of the pair of semispherical reinforcing domes being disposed at a first end of the reinforcing pipe, and the other one of the pair of semispherical reinforcing domes being disposed at a second end of the reinforcing pipe.

A wide-area power supply system has a small impact on the environment and is highly economical, as a wide-area power supply network that uses hydrogen energy without requiring conventional transmission towers, etc., the wide-area power supply system comprising: a primary power plant; a hydrogen production facility which produces hydrogen by using electricity from the primary power plant; a primary hydrogen storage facility distributed over a wide area; a secondary hydrogen storage facility distributed for each primary hydrogen storage facility; a regional power grid which sends power to power consuming facilities or dwelling units within a residential area; a secondary power generation facility which is installed within the residential area and converts hydrogen transported via the primary hydrogen storage facility or the secondary hydrogen storage facility into electric power; and a transportation means such as a trailer for transporting hydrogen between the hydrogen production facility and the primary hydrogen storage facility, between the primary hydrogen storage facility and the secondary hydrogen storage facility, and between the primary hydrogen storage facility or the secondary hydrogen storage facility and the secondary power generation facility.

A cryogenic tank for storing cryogenic fluids is disclosed. The cryogenic tank is typically configured to be mounted on a vehicle for supplying cryogenic fuel to a propulsion system of the vehicle. The cryogenic tank comprises an inner vessel for containing cryogenic fluids and an outer vessel surrounding the inner vessel to define a vacuum insulating volume therebetween. The outer vessel is configured to transmit static and/or dynamic loads, while the inner vessel is partially or completely isolated from such loads.

A tank for pressurized gas, such as hydrogen, comprises a structure made of composite material and a sensor for detecting and locating a deformation of the structure. The sensor comprises at least two first linear sensitive elements, which are sensitive to a non-localized elongation, and are rigidly attached the structure and laid out substantially parallel to each other. A deformation of the structure is localized in a section defined by at least one of the first linear sensitive elements.

Scalable greenhouse gas capture systems and methods to allow a user to off-load exhaust captured in an on-board vehicle exhaust capture device and to allow for a delivery vehicle or other transportation mechanism to obtain and transport the exhaust. The systems and methods may involve one or more exhaust pumps, each with an exhaust nozzle corresponding to a vehicle exhaust port. Upon engagement with the vehicle exhaust port, the exhaust nozzle may create an air-tight seal between the exhaust nozzle and the vehicle exhaust port. A first pipe may be configured to transport captured exhaust therethrough from the exhaust nozzle to. The captured exhaust may be at least temporarily stored in an exhaust holding tank connected to and in fluid communication with the first pipe

A system for dispensing a gaseous fuel from a liquefied fuel and a method for operating such a system are provided. The system includes a storage tank, a pressure sensor, a dispenser, a temperature sensor, and a vapor supply unit. The storage tank stores a liquefied fuel including phases of liquid and vapor. The pressure sensor is configured to measure a vapor pressure inside the storage tank. The dispenser is configured to receive the liquefied fuel and dispense the gaseous fuel to a receiving tank. The temperature sensor is configured to measure temperature of the dispenser. The system further includes a vapor supply unit fluidly coupled with the storage tank and configured to provide the vapor of the liquefied fuel from the storage tank into the dispenser or in thermally contact with at least one portion of the dispenser.
