to ${\delta }_2=\frac{\sqrt{3}P{R}_2}{2\left[\sigma \right]\cos \alpha }$
and the thickness of the wall of the conical portion changes linearly from δ.sub.2 to ${\delta }_3=\frac{\sqrt{3}P{R}_3}{2\left[\sigma \right]\cos \alpha },$
where P is predetermined operating pressure, R.sub.1 is

A compressor unit includes: a reciprocating compressor main body having a drive portion and a compression portion driven by the drive portion to compress a hydrogen gas; an electric motor that is a power source of the drive portion; a hydrogen supply flow path which is connected to a suction side flow path and to the compressor main body and through which a hydrogen gas flows; a fuel cell module that is disposed in the hydrogen station, generates electric power using a hydrogen gas guided through the hydrogen supply flow path, and supplies the generated electric power to the electric motor; and an inverter that adjusts a rotation speed of the electric motor.

Systems and methods for improving the efficacy of a wind turbine farm by providing a mechanical compressed air energy storage solution to provide power to the grid when electricity demand requires it. Specifically, a system for storing compressed air energy recovered from a wind turbine driven compressor. The system can include a primary spherical pressure vessel configured for fluid communication with a compressed air source and a secondary spherical pressure vessel in fluid communication with the primary spherical pressure vessel. Air stored in the pressure vessels can then be discharged to a combustion power generator to generate supplemental electrical energy or through a turbo expander to directly generate electricity.

Disclosed is an apparatus for assembling a solid hydrogen storage system. The apparatus includes a lower support installed to support a lower side of material blocks to be assembled, split covers assembled in multiple stages on an upper side of the lower support and forming therein a closed space in which the material blocks are capable of being assembled, the split covers being configured to be separated in a horizontal direction, and gas injection ports provided in the split covers to inject an inert gas into an inner space of the split covers.

Disclosed are gas cylinder assemblies for containing pressurized gas. The gas cylinder assembly has a polymeric liner and a low-permeability barrier layer. The polymeric liner a first end portion, a second end portion and a central body. The central body comprises an outer surface and an inner surface disposed between the first end and the second end. The gas cylinder assembly comprises a reinforcement structure wound over the central body. The gas cylinder assembly further comprises a metal foil interposed between the reinforcement structure and central body. The metal foil is configured to reduce permeation of contents of the polymeric liner.

Disclosed is a tank foot ring comprising: a body for supporting a pressurized tank made of polymeric material; and the body having an open end enclosing a hollow space or spaces on which a bottom portion of the pressurized tank rests and wherein the open end is in air flow communication with such hollow space or spaces, and an opposing surface for contacting a ground surface on which the foot ring rests. The opposing surface has a series of openings for drainage of water from the hollow space or spaces. Further provided is a collar for mounting on a top portion of a pressurized tank. The collar comprises: a body, a fastening system and a rotatable lid disposed on the collar. Further provided is a collar with a window cut-out for viewing tank data and a regulator mounting clip for securing a regulator of the tank in place during use.

A storage tank for a gas is provided. The storage tank includes a liner defining an internal compartment; a boss coupled to the liner; an interlayer covering a portion of the boss and the liner, the interlayer being non-pyrolyzed and including an interconnected web and pores having a diameter greater than the diameter of a hydrogen molecule and less than or equal to about 2 nm; and an outer shell including a carbon fiber reinforced composite, the outer shell covering the interlayer, except for an interlayer end that is in contact with the boss, so that the interlayer end defines an interlayer ring that is exposed to an external environment. The storage tank is configured so that when gas diffuses through the liner to the interlayer, the interlayer channels the gas out of the exposed interlayer ring. Methods of fabricating the storage tank are also provided.

A method for molding a composite pressure vessel liner to secure a boss to the liner is described. The method comprises providing a moldable liner having an end section with a neck and a port. A boss is positioned around the neck of the liner and the liner is heated and pressure is applied to mold the liner to form to the shape of the boss. The angle of the molded liner secures the boss in place around the liner and it is able to withstand high pressures. A tool for molding the liner and a method for using the tool is also described. The tool comprises a tool body and a pipe having external threads. The tool body abuts the liner and the boss. Winding the pipe exerts pressure on the liner, which when heated, forces the liner to mold to the shape of the boss.
