As a clean secondary energy source, hydrogen energy is gaining attention on a global scale. In addition to being explosive and flammable, hydrogen has the ability to mechanically harm metal objects. Every link in the hydrogen energy business chain carries the danger of leakage, fire, explosion, etc. According to statistical study of accident databases pertaining to hydrogen in the US and the EU, the primary causes of accidents are problems with system design, manufacturing/installation, human factors, safety management, and emergency response. Based on an investigation of the causes of safety accidents in high-risk locations, a systematic protection strategy for preventing hydrogen safety mishaps has been compiled. At the same time, specific control measures have been compiled in material selection and equipment processing to successfully prevent hydrogen damage mishaps in metal materials.
