A team of international experts has introduced a groundbreaking 'freezing engine' based on a new combustion method, challenging conventional efficiency records. Japan's IHI Power Systems, along with ClassNK, have made strides in developing an ammonia-fueled engine. Tests on the 280 mm bore four-stroke engine have shown promising results, with stable operation at an 80% ammonia fuel ratio. Ammonia's advantages over hydrogen include no CO2 emissions during combustion and easier storage and transport due to lower liquefaction pressure. The consortium aims to integrate the engine into various vessels, including a tugboat and an ammonia-gas carrier. Land-based tests have been successful, leading to plans for the world's first ammonia-powered ship by 2026. The consortium also focuses on establishing global standards for ammonia usage in maritime transport. The development of ammonia engines not only aids in reducing global carbon footprints but also enhances Japan's maritime industry, crucial for the nation's security. The ease of setting up ammonia refueling stations is highlighted as superior to the challenges faced with hydrogen infrastructure. The industry's shift towards ammonia signifies a new era in maritime fuel innovation, potentially posing a competitive challenge to hydrogen technology.
