T/CCGA 40011-2021 Liquid hydrogen Dewar safety technical specifications
Abstract
Main technical content: This document specifies the basic requirements for liquid hydrogen dewars, storage and use requirements, as well as emergency response plans and drills. This document is applicable to use under normal ambient temperatures (-40°C to 60°C), with the storage medium being liquid hydrogen refrigerated liquefied gas, a design temperature not exceeding -253°C, a nominal volume of 100L to 1000L, and an inner tank design pressure not exceeding 3.45barg (50psig). It is suitable for vacuum-insulated dewars that can be refilled repeatedly. This document is not applicable to portable on-board liquid hydrogen cylinders, liquid hydrogen tank trucks, liquid hydrogen tank containers, and fixed-type pressure storage tanks for liquid hydrogen
