In Japan, a significant development in the maritime sector is underway with the launch of a design project to create a hydrogen-fueled domestic coastal tanker. Sponsored by The Nippon Foundation, the project aims to demonstrate the viability of hydrogen as a clean energy source for ships. Working with ClassNK, Uyeno Transtech, Yanmar Power Technology, and Mitsui E&S Shipbuilding, the project has received the first approval in principle certificate for designs using liquid hydrogen as fuel. The tanker's design includes a capacity equivalent to 2,500 hydrogen fuel cell vehicles, with plans for a high-speed, four-stroke hydrogen-fueled engine. The vessel will feature hydrogen storage on deck, and the team aims to complete the project by 2026. This initiative represents a shift towards hydrogen as a sustainable solution for reducing CO2 emissions in the maritime industry, with potential implications for future vessel designs and operations.
