Abstract: An operating method is provided for a cryo-compressed tank for supplying cryogenic hydrogen to a consumer of a motor vehicle under supercritical pressure at 13 bar or more. In order to compensate for pressure loss resulting from hydrogen removal, the removed hydrogen that has been heated in a heat exchanger is conveyed to a heat exchanger, provided in the cryo-compressed tank, by way of a tank pressure regulating valve and a branch line, which branches off of a supply line leading to the consumer. After flowing through the heat exchanger, it is introduced into the supply line downstream of the branching off of the branch line. Over a period of time that significantly exceeds the cycle times of a conventional frequency valve, either the removed amount of hydrogen is guided without limitation into the heat exchanger, provided in the cryo-compressed tank, the tank pressure regulating valve being completely open, or no return of the heated hydrogen into the heat exchanger occurs at all. Downstream of the branching off of the branch line, the supply line has a pressure regulating unit, which ensures that irrespective of the changes in the pressure in the supply line caused upstream of the pressure regulating unit by switching the tank pressure regulating valve, a sufficient and continuous supply of hydrogen to the consumer at the pressure required is guaranteed.

Abstract: In one aspect the present disclosure relates to a method of manufacturing a cryogenic pressure vessel. The method may include providing a metal lined, composite wrapped vessel which has a boss. The method may further include securing an inlet to the boss, and then encapsulating the metal lined, composite wrapped vessel within a metallic layer in a vacuum controlled environment to form an encapsulated inner tank subassembly. The method may further include securing at least one support to an exterior of the encapsulated inner tank subassembly, and within the controlled vacuum environment, applying a metal coating over the encapsulated inner tank subassembly and the at least one support to form a metal coated, encapsulated inner tank subassembly. The method may further include, within the controlled vacuum environment, encapsulating the metal coated, encapsulated inner tank subassembly within a metallic vacuum jacket, which forms the cryogenic pressure vessel.

Abstract translation: 提供了一种用于在超过13bar或更高的超临界压力下向机动车辆的消费者提供低温氢的低温压缩罐的操作方法。 为了补偿由除氢导致的压力损失，已经在热交换器中被加热的已去除的氢气通过储罐压力调节阀和分支管线输送到设置在低温压缩罐中的热交换器 ，它们分支到通向消费者的供应线。 在流过热交换器之后，将其引入到分支线分支下游的供应管线中。 在显着超过常规频率阀的循环时间的一段时间内，去除量的氢被引导而不限于设置在冷冻压缩罐中的热交换器，罐压力调节阀完全打开，或 根本不会发生加热的氢气进入热交换器的情况。 在分支线分支的下游，供应线路具有压力调节单元，其确保不管通过切换罐压力调节阀而在压力调节单元上游产生的供应管路中的压力变化，足够 并保证在所需压力下不断向消费者供应氢气。
