With the global consensus on building a safe and stable green energy system, investment and innovation in the clean hydrogen industry continue to increase. According to the "Hydrogen Energy Future Development Trend Research Report" released by the International Hydrogen Energy Committee, the global demand for hydrogen energy will increase tenfold by 2050. Based on the huge application potential of hydrogen energy and the enormous value of its industrial chain, its development and utilization have not only become an important path for many countries to achieve energy transition, but also risen to an important field of international competition. Developed countries and regions such as Europe, Japan, and the United States are focusing on the layout of the clean hydrogen industry. Developing regions such as Africa and Latin America are actively promoting the landing of clean hydrogen projects based on their resource endowment advantages. Hydrogen energy is gradually developing into a new highlight of global energy transformation and cooperation.
