The International Council on Clean Transportation (ICCT) has released a new report highlighting the potential for green shipping corridors along China’s coastal shipping routes.
The study examined the feasibility of powering ships with renewable energy sources such as ammonia, hydrogen, methanol or batteries without having to refuel during their journey.
The study identified three main routes as solid opportunities for these green shipping corridors: two interregional routes connecting the Pearl River Delta to the Bo Sea and the Yangtze Delta to the Bo Sea, and an intraregional route within the Yangtze Delta region. These regions are home to some of the world’s largest ports, including Tianjin, Shanghai and Shenzhen.
For example, container ships could use renewable marine fuels to travel the 1,400 nautical mile route from Tianjin to Shenzhen.
The study estimates that 6,000 tonnes of ammonia, methanol or 900 tonnes of renewable hydrogen will be needed to power the first wave of zero-emission ships on these routes.
This would require a deployment of 44-60 GWh of renewable electricity by 2030. However, the cost of renewable hydrogen is expected to reach USD 7.60/kg by 2030, which is significantly higher than conventional marine fuels. Achieving a 32% cost reduction by 2050 will require significant policy action to increase the viability of these routes.
The researchers also found that by December 2023, there were 44 green shipping corridor initiatives worldwide, but none had been fully implemented.
According to the study, inland routes can be advantageous due to the more homogeneous involvement of the parties involved. In other cases, a single company can handle both the cargo and the vessels, making it easier to set up such corridors.
The study highlights the need for continued research and policy support to exploit the full potential of green shipping corridors and shape the transition to a more sustainable maritime sector.
