Abstract:

As a“star of tomorrow”in the field of new energy, hydrogen energy has been gradually developed and promoted globally. However, safety is still a key bottleneck problem in the entire life cycle of hydrogen energy, and high pressure is the most prominent risk factor among them, which is likely to cause major safety accidents such as hydrogen leakage, diffusion, and even combustion and explosion. Based on this, the research status of the evolution process and internal mechanism of typical accidents such as high-pressure hydrogen leakage and diffusion, leakage spontaneous combustion, jet fire and gas cloud explosion are summarized and the current shortcomings are summarized, and the future development direction is proposed, which may have guiding significance on the research of hydrogen safety, and prevention and control of accidents.

Key words: hydrogen, safety, high-pressure hydrogen storage, leakage, explosion, status and shortcomings

摘要:

氢能作为新能源领域的“明日之星”,已经逐步在全球范围内发展与推广。然而,安全性依然是氢能全生命周期的关键瓶颈问题,高压又是其中最为突出的风险要素,容易引发氢气泄漏、扩散,甚至燃烧、爆炸等重大安全事故。基于此,重点总结了高压氢气泄漏扩散、泄漏自燃、喷射火和气云爆炸等典型事故演化过程及内在机理的研究现状并归纳了当前的不足之处,提出了未来发展方向,对氢能安全科学研究及事故防控具有指导意义。
