ClassNK has granted Approval in Principle (AiP) for the design concept of the world's first oil tanker fueled by liquid hydrogen (LH2). Collaborating with Mitsui E&S Shipbuilding, Uyeno Transtech, and Yanmar Power Technology, the revolutionary vessel features a hydrogen-fueled engine and an electric propulsion system. The vessel, part of the Nippon Foundation's initiative for zero-emission ships, aims to promote hydrogen as a crucial alternative fuel. ClassNK's evaluation confirmed that the design meets safety and performance standards, setting a new benchmark in maritime engineering. With a hydrogen capacity equivalent to 2,500 hydrogen fuel cell vehicles, the tanker is projected to reduce CO2 emissions by 6,000 tons annually. The project targets to complete the vessel by 2025 and have it operational by 2026. This approval marks a significant advancement in decarbonization efforts, aligning with global strategies like Japan's Basic Hydrogen Strategy and the EU's LH2 Craft project. ClassNK's dedication to safety and innovation further underscores the importance of reducing the shipping industry's carbon footprint.
