Hydrogen is an attractive energy carrier that requires high effort for safe storage. For ensuring safety, storage cylinders must undergo a challenging approval process. Relevant standards and regulations for composite cylinders used for the transport of hydrogen and for its onboard storage are currently based on deterministic (e.g. ISO 11119-3) or to some respect semi-probabilistic criteria (UN GTR No. 13; with respect to burst strength).

This paper provides a systematic analysis of the load cycle properties resulting from these regulations and standards. Their characteristics are compared with the probabilistic approach of the Federal Institute for Materials Research and Testing BAM. The most important aspect of comparing different concepts is the rate for accepting designs with potentially unsafe or critical safety properties. This acceptance rate is analysed by operating Monte-Carlo simulations over the available range of production properties.

蒙特卡洛分析氢复合气瓶的最小负荷循环要求

氢气是一种有吸引力的能源载体,需要付出巨大的努力才能安全存储。为了确保安全,储气瓶必须经过具有挑战性的批准程序。目前,用于运输氢和船上存储的复合气瓶的相关标准和法规基于确定性(例如ISO 11119-3)或某种程度上的半概率性标准(UN GTR第13号;关于破裂强度) )。

本文对这些法规和标准产生的负载循环特性进行了系统分析。将其特性与联邦材料研究与测试研究所BAM的概率方法进行了比较。比较不同概念的最重要方面是接受具有潜在不安全或关键安全属性的设计的比率。通过在可用的生产属性范围内进行蒙特卡洛模拟来分析该接受率。
