At the critical stage of global low−carbon transition and climate governance, hydrogen energy, leveraging its zero−carbon properties and energy interconnection advantages, has emerged as a strategic cornerstone for addressing the "carbon neutrality" dilemma and driving the restructuring of the energy system. This paper focuses on the development of the hydrogen energy industry, elaborates on the urgency of energy transition against the backdrop of global warming, and clarifies hydrogen energy's core value in safeguarding energy security, promoting industrial upgrading, and boosting economic growth. It analyzes the development trends of the global and Chinese hydrogen energy industries, covering the strategic layouts of various countries, progress in renewable energy−based hydrogen production, as well as China's remarkable achievements in policy support, industrial scale expansion, application diversification, and price reduction. Furthermore, the paper examines the technical, economic, application−oriented, and policy−related bottlenecks confronting the industry, identifies significant development opportunities brought by technological breakthroughs, integrated development, policy dividends, and market demand, and proposes a development path for building a modern hydrogen energy industry system through technological innovation, management innovation, model innovation, and institutional innovation. The paper emphasizes that the hydrogen energy revolution is a protracted battle, requiring systematic layout, comprehensive utilization of renewable energy advantages, in−depth exploration of industrial application scenarios, improvement of market mechanisms, and accelerated efforts to make hydrogen energy a core engine driving energy transition, industrial upgrading, and high−quality economic and social development.
