Japan Sustainable Marine Fuel Sector: Growth Drivers and Challenges

Growth Drivers

• Decarbonization targets and global alignment: Japan’s maritime fuel plan is aligned with the IMO’s GHG goal that aims at reducing emissions by 20-30% by 2030 and achieving zero emissions by 2050. These benchmarks lead to the investment in transitional fuels and propulsion technologies in the short-term. In August 2024, MOL’s Wind Challenger got approval from ClassNK for the first LNG vessel with wind assistance technology. This can be attributed to the commercial use of hybrid propulsion systems. The need for regulation, backed up by Japan’s Green Growth Strategy, creates urgency to demand cleaner fuels, thus supporting the market. These policies make sure that decarbonization is not an abstract concept but a reality in the maritime industry.
   
• Fuel diversification and strategic collaborations: Japan shipping companies are transitioning to ammonia, LNG, methanol, and e-fuels to hedge their bets on the future. In June 2024, NYK, JERA, and Resonac successfully provided the first ammonia bunkering for a tugboat using truck-to-ship transfer, signifying ammonia fuel preparedness. Such partnerships guarantee technological readiness and the legal requirements of the company. These fuels are crucial for shipping since the industry is under pressure to reduce carbon intensity. As the volume of international trade increases, Japan’s diversified supply portfolio improves energy security and minimizes long-term transition risk.
   
• Infrastructure expansion and international partnerships: Strategic partnerships between the public and private sectors are improving refueling and supply chain management. In December 2023, Maersk signed a deal with Yokohama and Mitsubishi Gas Chemicals to develop methanol bunkering terminals. These terminals enable Maersk to accommodate its green methanol-powered container ships. Carbon-neutral projects are also supporting port infrastructure development in Kobe and Nagoya. The transition to next-generation fuels requires cooperation between municipalities and corporations to expand refueling stations. 

Challenges

• Immature ammonia and methanol bunkering networks: However, the infrastructure needed to support ammonia and methanol as mass-scale fuel remains weak in Japan, even with pilot projects. Nevertheless, the creation of such networks within domestic contexts continues to be a difficult task. Fuel flammability and safety measures during handling also pose additional challenges. The absence of scaled ports and safety systems may slow down full commercialization. This readiness gap is set to be addressed by investment in homegrown infrastructure.
   
• Cost-intensive port and vessel retrofitting: The transition to multi-fuel compatible vessels and ports entails large-scale investments in new ship designs and modifications to ports. Subsidies and tax incentives are still being introduced, which slows down the speed of private investment. Moreover, the ownership structure of Japan’s coastal fleet is dispersed, which hinders the implementation of uniform upgrades. Government co-financing and better definition of compliance deadlines can help overcome these issues. In order to counterbalance high conversion costs, strategic alignment across port authorities is crucial.
