Japanese shipping industry is looking towards methanol as a bridging fuel to reduce greenhouse gas emissions in the maritime sector. The International Maritime Organization has set ambitious targets for net zero emissions, leading to a surge in methanol-powered vessels worldwide. Japan, in particular, is expected to witness an increase in methanol-fueled ships from 2027 onwards, with plans to commission more vessels to meet emission reduction goals. The city of Yokohama has initiated a study on methanol bunkering, signaling a shift towards cleaner marine fuels. Japanese firms are actively investing in e-methanol production projects to secure fuel supply for future operations. However, methanol is viewed as a temporary solution due to its limited emission reduction capabilities. To achieve long-term sustainability, Japan is focusing on the development of ammonia and hydrogen-fueled ships, with financial support and incentives in place. The Ministry of Land, Infrastructure, Transport, and Tourism is actively promoting the utilization of cleaner fuels like ammonia and hydrogen by providing significant funding for research and development. While methanol remains a vital transition fuel, Japan's strategic vision is centered on the adoption of zero-emission technologies to achieve a greener maritime industry in the coming years.
