> News > China’s Major Ports Aim to Develop Green Shipping Corridors
10 October 2024
A recent report by the International Council on Clean Transportation (ICCT) highlights the potential for developing green shipping corridors along China's coastal routes.
The report investigates the possibility of using renewable energy sources like ammonia, hydrogen, methanol, or batteries to power ships, eliminating the need for refueling during voyages.
The study identifies three key routes with the potential for green shipping corridors: two interregional routes connecting the Pearl River Delta to the Bo Sea and the Yangtze River Delta to the Bo Sea, as well as an intraregional route within the Yangtze River Delta. These areas are home to major global ports such as Tianjin, Shanghai, and Shenzhen. For example, container ships could potentially travel 1,400 nautical miles from Tianjin to Shenzhen using renewable marine fuels.
According to the study, the initial fleet of zero-emission ships on these routes would require around 6,000 tonnes of ammonia or methanol, or 900 tonnes of renewable hydrogen. By 2030, this would demand 44-60 GWh of renewable electricity. However, the cost of renewable hydrogen is projected to be $7.60 per kilogram by 2030, significantly higher than traditional marine fuels. To make these routes economically viable, a 32% reduction in costs by 2050 would be necessary, which would require substantial policy changes.
The study also notes that, as of December 2023, there are 44 green shipping corridor initiatives worldwide, but none have been fully implemented yet. It suggests that domestic routes could be more feasible due to simpler stakeholder dynamics, where a single company might manage both the cargo and vessels, simplifying the process of establishing green corridors.
The report emphasizes the need for ongoing research and policy support to fully realize the potential of green shipping corridors and promote a transition to a more sustainable maritime industry.
