Under the goal of "emission peak and carbon neutrality", the hydrogen energy industry with standardization and orderly development is an important part of China's energy structure in the new era and new stage, and how to build a standardization system to ensure the high-quality development of China's hydrogen energy industry is a subject worthy of deep consideration. This paper firstly discusses the significance of hydrogen energy standardization in guiding industrial development, reducing trade barriers and enhancing industrial competitiveness, etc. The International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) are the most important international standardization organizations for hydrogen energy, the European Union is making every effort to build a regional standard system for hydrogen energy, the United States has the most complete industrial standard system for hydrogen energy, and the construction of Japan's standard system for hydrogen energy safety is worthy of our reference. Meanwhile, there are also problems such as insufficient market foresight and feasibility, lack of standards in subdivided fields, imperfect coordination mechanism of standardization groups, and limited participation in formulating international standards. By comparing the standardization system of hydrogen energy industry in China and abroad, the study provides inspiration and reference for the development of standardization of hydrogen energy industry in China.
