Abstract: With increasing stress in global climate and the acceleration of energy transition, hydrogen has caught attention of the world for its advantages of clean, flexible and efficient and abundant application scenarios. Since 2000, Japan, the US, Europe and the other developed countries attach importance to hydrogen and consider it in their energy strategies, and make substantial progresses on development of hydrogen industry through efforts in strategic layout, project development and demonstration application. This article summarizes and analyzes hydrogen industry strategic points, targets and development levels of each major country, compares and analyzes basic researches and technical reserves of China and prior countries on hydrogen. Research indicates that, a new wave of hydrogen economy has started in the world, each main country is accelerating layouts of hydrogen economy; comparing with prior countries on hydrogen in the world, China still has gaps on top-level design, industrial technology control and industry development level. The paper then suggests that China should: further strengthen strategic guidance and industry-academia-research collaboration; increase localization level of key materials and devices; give full play to resource advantages, actively distributing green hydrogen economy; and pay attention to hydrogen downstream diversified utilization.
