Abstract:
The present disclosure provides a pressure vessel 10 (sometimes known as a composite overwrapped pressure vessel or “COPV”) comprising carbon fiber 20 (such as carbon fiber 20 filaments) wrapped around a tank liner 30.
Abstract:
A fluid pressurization device 10 comprises a pressure container 12 and a first bladder 14, asecond bladder 16 and a sheet 18, that are located in the pressure container 12. The bladders14 and 16 have pipe connectors 32 and 40, respectively, for filling/discharging fluid from thebladders. The bladders 14 and 16 are located in the container 12 adjacent one another, withthe bladder 16 being folded in concertina fashion and the sheet 18 being wrapped around thebladder 16 to form a roll surrounding the folded bladder 16. In use, the bladder 14 is filled with a combustible fluid such as oxygen and the bladder 16 is filled with compressed air to a relativelyhigher pressure than the oxygen in the bladder 14 for pressurizing the oxygen contained therein.As oxygen is delivered from bladder 14, the sheet 18 unravels gradually, allowing the bladder 16to continue to exert a force on the bladder 14.
Abstract:
The invention relates to a passenger automobile having a pressure tank (D) which is arranged along the vehicle longitudinal axis (x). So that a larger amount of fuel can be carried, the pressure tank (D) comprises at least one conical part (K).

Abstract:
Embodiments of the present invention relate to compressed gas storage units, which in certain applications may be employed in conjunction with energy storage systems. Some embodiments may comprise one or more blow-molded polymer shells, formed for example from polyethylene terephthalate (PET) or ultra-high molecular weight polyethylene (UHMWPE). Embodiments of compressed gas storage units may be composite in nature, for example comprising carbon fiber filament(s) wound with a resin over a liner. A compressed gas storage unit may further include a heat exchanger element comprising a heat pipe or apparatus configured to introduce liquid directly into the storage unit for heat exchange with the compressed gas present therein.

Abstract:
The vessel of a heat storage and release apparatus is provided with a shell made of metallic material with an internal cavity for containing a heat storage and release device and for guiding gas-flow, a first opening through the shell for a flow of gas at high temperature and high pressure in and out of the cavity, a second opening through the shell for a flow of gas at low temperature and high pressure in and out of the cavity, and a lining of thermally insulating material covering only partially the internal surface of the cavity; the lining is located at least in the region where the first opening is located, i.e., where the temperature is higher; in this way, the temperature of the shell can be controlled. Such heat storage and release apparatus can be provided in an energy production plant as a component of an energy storage and release system to be used for compensating differences between energy produced and energy demanded.
