China is at the forefront of a green maritime revolution, driven by its ambitious environmental goals. With a 'dual carbon' strategy aiming to peak carbon emissions before 2030 and achieve carbon neutrality by 2060, the country is actively transforming its water transportation system. The Ministry of Transport highlighted the adoption of greener fuels in inland water transport, with a diverse fleet that includes LNG, battery-powered electric, methanol fuel-powered, and hydrogen fuel cell-powered vessels. Notable vessels like the COSCO SHIPPING Yangpu and Yuan Hai Kou are pioneering dual-fuel technologies to reduce carbon dioxide emissions significantly. In Qingdao Port, the first hydrogen-powered 5G smart terminal in Asia, sustainable practices are integrated with renewable energy sources like PV systems to cut carbon emissions. The port's innovative hydrogen-powered rail crane and energy management systems showcase its commitment to green, low-carbon growth. Similarly, Yantian Port in Shenzhen leads in shore power systems, drastically reducing ship emissions. The Guangdong-Hong Kong-Macau Greater Bay Area ports are embracing AI, 5G, and new energy-powered machinery to enhance efficiency. China's efforts extend to international collaboration for establishing green shipping corridors and promoting global transition to low-carbon shipping. By leveraging technologies like AI, big data, and blockchain, China is paving the way for a sustainable and environmentally friendly maritime sector. The country's dedication to structural carbon reduction, new energy application, pollution control, and technological integration underscores its commitment to building a clean, low-carbon maritime energy system.
