NYK Line subsidiary Kinkai Yusen on Tuesday (9 June) said it will conduct a demonstration operation using biofuel refuelled at Hakata Port on 16 June on the RoRo vessel Nanotsu , which operates between Hakata Port and Tsuruga Port. The company said it will be the first instance of a domestic RoRo vessel operating using biofuel at Hakata Port. The biofuel (B24) which will be used will comprise 24% biofuel and conventional marine fuel, and is expected to reduce greenhouse gas (GHG) emissions without requiring major modifications to existing ship equipment. “The procurement of biofuel will be carried out in cooperation with Idemitsu Kosan Co Ltd and Itochu Enex Co Ltd,” it said in a statement.   Photo credit: MarineTraffic / Tetsuya Published: 12 June, 2026
