On October 21, Tokyo's Oi Container Terminal at Tokyo Port initiated cargo handling operations using a hydrogen-fuelled RTG crane. This effort is part of a broader decarbonisation strategy following an agreement in May 2023 between the Tokyo Metropolitan Government Bureau of Port and Harbour and key partners like Nippon Yusen Kabushiki Kaisha (NYK), Uniex NCT Co., Mitsui E&S Co., and Iwatani Corporation. The hybrid RTGs, developed by Mitsui E&S Machinery, started operating at Oi Container Terminal with plans for eventual retrofitting to hydrogen fuel cell power supply to reduce emissions. NYK Line announced the conversion of the first RTG and aims to convert all four units in the future. Hydrogen is sourced from a production plant in Chiba Prefecture, pressurised at the wharf, and filled into tanks inside the RTG during operations to ensure sustainable cargo handling. Each project participant has specific responsibilities, with the Port and Harbor Bureau promoting hydrogen use, NYK Line overseeing coordination, Uniex NCT Corporation managing operations, Mitsui E&S Co. conducting equipment conversion, and Iwatani Corporation handling hydrogen procurement and supply. This initiative aligns with NYK Line and UNI-X's goal to achieve carbon neutrality by 2040 by converting all cargo handling equipment to zero-emission alternatives. The effort extends to NYK Kobe Container Terminal and Kobe International Container Terminal, showcasing a widespread shift towards sustainable practices within the port industry.
