Hydrogen is a clean, efficient and high-quality energy carrier with immense potential in various sectors, including transportation, industry, buildings and power generation. Poised to play a critical role in the global energy transition and industrial revolution, it holds promise as a key solution for decarbonizing energy systems and achieving climate mitigation goals. China, as the world's largest carbon emitter and hydrogen producer, is actively exploring and promoting the widespread adoption of hydrogen technologies in its future energy system. China boasts abundant renewable resources and has a massive domestic market for clean energy, providing a conducive environment for the development of a robust new energy industry and economy where hydrogen could have a crucial impact. In recent years, hydrogen has taken center stage in China's public policy discussions, and the government has allocated significant resources for hydrogen technology research and market development.
