Hydrogen energy storage explosion problem

Why is hydrogen explosion a major problem in industrial production processes?

As a carbon-free clean energy source and energy carrier, the risk of hydrogen explosion is one of the major problems in industrial production processes and has attracted a lot of attention from research scholars.

What are the key issues concerning hydrogen safety?

Through an analysis of literature, in combination with our practical survey analysis, this paper reviews the key issues concerning hydrogen safety, including hydrogen incident investigation, hydrogen leakage and diffusion, hydrogen ignition, and explosion. Hydrogen (H 2) energy has been receiving increasing attention in recent years.

Why is a delayed hydrogen explosion a risk scenario?

The delayed explosion of an accidental release of hydrogen under high pressure is an important risk scenario for safety studies of production plants, transport lines, and charging lines for fuel cell vehicles.

Why is hydrogen a problem?

Hydrogen embrittlement: hydrogen can embrittle metals, which can cause problems with the structural integrity of equipment and infrastructure as well as pose a safety risk. Transport safety: transporting hydrogen safely over long distances can be a challenge due to its low energy density and the need for specialised containers or pipelines.

Why are hydrogen explosions so common?

The probable reason is that hydrogen is widely used as the most promising renewable energy source in the 21st century, and hydrogen explosion accidents with the use of hydrogen have become increasingly frequent (Ma et al. 2014; Shang et al. 2022a). Thus, scholars have begun to focus on studying hydrogen explosion processes.

What happens if hydrogen explodes?

Hydrogen ignites and explodes when the burning condition is satisfied. Ignition and explosion produce higher temperature and pressure fields, which will cause great harm to surrounding people and property. In addition, compressed hydrogen spontaneously ignites without any apparent ignition source if it is suddenly released into air.
