中国氢能“超车”日本！专利登顶背后藏着哪些惊喜？

Core Insights - China has surpassed Japan in hydrogen energy patent competitiveness, securing the top position globally, marking a significant shift in the industry landscape [1][3]. Patent Leadership - From 2013 to 2022, China led in nearly 180,000 hydrogen energy patents across four key areas: manufacturing, storage, transportation, and safety management [3]. - Previously, Japan was the dominant player in hydrogen technology, but China has now overtaken it, showcasing years of strategic development in the hydrogen sector [3]. Policy and Industry Support - The Chinese government's policies, particularly under the "dual carbon" goals, have significantly boosted the hydrogen energy sector, with various plans and subsidies encouraging research and development [3]. - China is the largest producer and consumer of hydrogen globally, with a complete industrial chain from electrolyzer manufacturing to green hydrogen production, facilitating rapid technological advancements and cost reductions [3]. Technological Advancements - Chinese companies dominate the electrolyzer technology field, holding 60% of global manufacturing capacity, leading to a surge in overseas orders [3]. - Major players in solar and wind energy, such as Longi and Sungrow, are leveraging their strengths to enhance hydrogen production capabilities, further solidifying China's position in the green hydrogen market [3]. Societal Impact - The advancements in hydrogen energy technology are expected to directly benefit consumers, with potential applications in hydrogen fuel vehicles and green production processes in factories [4]. - The transition to hydrogen energy is anticipated to improve air quality and overall living standards, contributing to a cleaner environment [4]. Future Outlook - While patent leadership is a significant achievement, the hydrogen industry still faces challenges in cost and commercialization, indicating that further development is needed [4]. - The accumulation of patents is seen as a foundational step for the industry, suggesting that the transition from laboratory innovations to practical applications in daily life is imminent [4]. - The shift in hydrogen energy leadership from Japan to China serves as a reminder of the rapid advancements possible in the renewable energy sector when driven by strong policy and innovation [4].
