Abstract:

Greenhouse gas emissions from the maritime sector are rising, conflicting with the climate goals of the Paris Agreement. This sector has struggled to transition to zero or near-zero emission fuels due to regulatory and financial barriers. To address these challenges, the concept of green shipping corridors (GSCs) has emerged, aiming to overcome financial obstacles and accelerate innovation in decarbonization technology.

This study investigates the feasibility of establishing GSCs for China’s coastal shipping. Researchers assess whether the ships could be powered by renewable hydrogen, methanol, ammonia, or batteries without the need to refuel en route. Three routes were identified as potential first mover candidates for GSCs. Finally, to understand the cost of enabling these routes, researchers analyzed demand and cost of renewable marine fuels for the first zero-emission vessels to be deployed on these routes.
