The present invention relates to a cryogenic vessel (300a, 300b) having an inner container (301), an outer container (302), an intermediate space (303) between the inner container (301) and the outer container (302) which can be evacuated, and having at least one fluid distribution container (200), which has an internal volume which extends proceeding from one wall of the inner container (301) into the intermediate space (303), is arranged at least partially within the intermediate space (303) and is fluidically connected to the inner container (301), wherein the internal volume of the fluid distribution container (200) is delimited by a wall which has openings (211, 212, 213) that are designed for the connection of one line (311, 312, 313) each or are each connected with one such line (311, 312, 313). The wall (121, 221) has a convex section (101, 201), wherein a wall thickness of the wall at at least one point is less than 90% of a wall thickness of the inner container (301). The invention also relates to a fluid distribution container (100, 200) and to a method for producing a cryogenic vessel (300a, 300b).

A hydraulic compressed air energy storage system includes air and liquid tanks, each of which includes interdependent volumes of liquid and air. Each tank includes dedicated passages through which incoming air may be fed, forcing outflow of liquid, or incoming liquid may be fed, forcing outflow of air. Compressed air tanks are connected to a first group of the air and liquid tanks. The system further includes a pump and a liquid turbine, the liquid turbine being electrically connected to a generator for generating electric power. During charging of the system, liquid is pumped through the first group of air and liquid tanks, and air is expelled from the first group of air and liquid tanks and compressed in the compressed air tanks. During discharging of the system, compressed air is released from the compressed air tanks, and said compressed air pumps liquid through the liquid turbine, thereby generating electricity.

Disclosed is a machine learning energy management system that regulates incoming energy sources into compressed air storage operations and energy generation. Compressed air is directed into a thermoregulation system that cycles storage tanks according to physical qualities. A boost impulse creates energy to initiate the electrical energy generation. The compressed air operations and energy generation leverage the heating and cooling of an external HVAC system to improve performance and conservation of the heating and cooling for an external building. The system combines real-time data, historical performance data, algorithm control, variable air pressure for demand-based generation, tank-to-tank thermal cycling, building air heat exchanger, and boost pulsation to achieve optimized system efficiency and responsiveness.

A pressure vessel with a flushing lance, a transport container with pressure vessels and methods of filling and producing this pressure vessel are disclosed which comprises an inner vessel, an outer layer applied on the inner vessel, a valve connection piece arranged on one of the terminal caps of the inner vessel and a hollow flushing lance that is open to the outside and is guided through the valve connection piece and held therein in a sealing manner, wherein the flushing lance protrudes into the storage volume and is provided with a perforation along its entire length up to a first end of the flushing lance facing the terminal cap that lies opposite the valve connection piece in the storage volume for a gas exchange with the storage volume, wherein the flushing lance extends to the terminal cap which lies opposite the valve connection piece.

A pressure vessel can include a liner having a cylindrical section and a pair of dome sections; and a reinforcement layer constituted by a fiber-reinforced resin material and formed on the outside of the liner. The pressure vessel's reinforcement layer can include protruding sections formed so as to protrude at the dome sections by high-angle helical winding; and a central section formed by hoop winding which spans the area between each peak of the pair of protruding sections, or by approximate hoop winding in which winding is carried out at a higher angle than the high-angle helical winding.

To suppress the degradation of sealing property of a pressure vessel and the deterioration of a sealing member, and to reduce the workload and cost of manufacture, a blow molding device includes a pair of molds configured to be clamped to sandwich a parison from both lateral sides, and a blow pin configured to form a neck portion together with the molds. The blow pin includes a blow pin body portion having an outer circumferential surface of a shape corresponding to an inner circumferential surface of the neck portion, and a ring portion forming an annular recess portion between the blow pin body portion and the ring portion to form an outer circumferential surface of a tip portion of the neck portion, which is a smooth surface without any parting line.
