Mitsui E&S said it completed integrated testing of ammonia-fuelled engines and fuel supply systems at its Tamano Works by the end of fiscal 2025 , confirming the systems' safety and reliability. The company said the expanded facility will help improve the performance and wider adoption of ammonia propulsion systems while supporting its goal of becoming a supplier of integrated marine propulsion systems. The project is backed by Japan's Zero-Emission Ships Construction Promotion Project . Ammonia is widely seen as a promising marine fuel to help decarbonise shipping. While commercial adoption is still in its early stages, the industry is gradually moving towards ammonia.  Ship & Bunker News Team To contact the editor responsible for this story email us at [ema
