健康和安全

轻、简单、丰富。这就是氢 (H2)。由于氢在燃烧时不会产生二氧化碳 (CO2) 排放,因此它有望成为全球能源转型、污染修复和地球脱碳的关键

事实上,氢气的生产、分配和使用量正在猛增,部分原因是环境立法和全球对清洁能源的需求。  

氢气作为燃料来源极具吸引力,因为它既环保可持续然而,在更广泛地采用氢之前,还有很多工作要做。也就是说,氢气必须安全生产、分配和使用。 

尽管氢有潜力成为一种广泛使用的清洁能源,但仍存在非常现实的安全问题需要解决。这就是挑战和悖论。 

一方面,氢独特的化学性质使其成为一种令人兴奋的燃料替代品。另一方面,这些相同的特性也可能带来这些危险: 

氢气 有泄漏的倾向。

它  无色、无臭、无味,人类感官无法察觉。

氢气 具有不可见的高温火焰,热辐射低。

它 爆炸速度快,比天然气更具爆炸性。

泄漏监测和检测 

据美国能源部称,所有燃料(包括氢气)都会造成一定程度的危险。虽然氢的无毒性质和释放后迅速消散的能力只是氢可能比其他燃料更安全处理的几个原因,但仍然需要安全使用。 

“具体来说,氢气在空气中的可燃浓度范围较广,并且比汽油或天然气的点火能量更低,这意味着它更容易点燃。因此,充分的通风和泄漏检测是安全氢气系统设计中的重要元素。由于氢气燃烧时产生几乎看不见的火焰,因此需要特殊的火焰探测器。”

因此,对于氢气生产商、分销商和用户来说,持续监控至关重要。

Hydrogen: big potential, big safety challenges

Health & Safety

Light, simple, abundant. That’s hydrogen (H2). Because hydrogen doesn’t create carbon dioxide (CO2) emissions when burned, it holds the promise of becoming essential for global energy transformation, pollution remediation, and decarbonising the planet

In fact, H2 production, distribution, and usage is skyrocketing, having been fuelled, in part, by environmental legislation and worldwide demand for clean energy.  

H2 is extremely attractive as a fuel source because of its ability to be both environmentally friendly and sustainable. However, before the adoption of hydrogen becomes even more widespread, there is work to be done; namely, H2 must be produced, distributed, and used safely. 

Despite hydrogen’s potential to become a widespread clean-energy source, there are very real safety issues to contend with. Therein lies the challenge and the paradox. 

On one hand, hydrogen’s unique chemical properties make it an exciting fuel alternative. On the other hand, those same properties are what hold the potential for these dangers: 

Hydrogen has a propensity to leak. 

It is colorless, odorless, and tasteless, making it undetectable by human senses.  

Hydrogen has an invisible, high-temperature flame with low thermal radiation. 

It is fast detonating and more explosive than natural gas. 

Leak monitoring and detection 

According to the U.S. Department of Energy, all fuels – including hydrogen – pose some degree of danger. While hydrogen’s non-toxic nature and ability to dissipate quickly when released are just a few of the reasons hydrogen may be safer to handle than other fuels, there’s still a need for safe use. 

"Specifically, hydrogen has a wide range of flammable concentrations in the air and lower ignition energy than gasoline or natural gas, which means it can ignite more easily. Consequently, adequate ventilation and leak detection are important elements in the design of safe hydrogen systems. Because hydrogen burns with a nearly invisible flame, special flame detectors are required."

Consistent monitoring, therefore, is imperative for hydrogen producers, distributors, and users.

MSA has been at the forefront of hydrogen gas and flame detection solutions. As one of the world’s largest and most experienced global suppliers of gas and flame detection equipment, MSA has pioneered the detection of combustible gases such as hydrogen, methane, and propane.  

The company’s in-house Research and Development team develops, tests, and manufactures its own fully certified portfolio of products and safety solutions – including the very latest hydrogen gas and flame detection technologies.
