In a groundbreaking move, Tokyo Port Bureau and several companies have initiated the use of a hydrogen fuel cell generator to power a tire-type gate crane at the Oi Container Terminal. This marks the first time in Japan that cargo handling operations are being conducted with an RTG powered by hydrogen. The project, which began on October 21, 2024, aims to promote the widespread adoption of hydrogen in cargo handling machinery and facilitate the decarbonization of Tokyo Port. The implementation involves retrofitting diesel generators of cargo handling machinery with FC power generation units, which utilize hydrogen as fuel and emit no CO2 during power generation. Additionally, a hydrogen supply system has been established to transport hydrogen from a production plant in Chiba Prefecture to the terminal, where it is pressurized and filled into the RTG's hydrogen tank. Cargo handling operations are being carried out using RTGs equipped with FC power generation units. Data collection and analysis are being conducted to identify and address any operational challenges. The project, located at 2-5-2 Hachioji, Shinagawa-ku in Tokyo, is scheduled to run from October 21, Reiwa 6 to the end of March Reiwa 7. This initiative signifies a significant step towards a more sustainable and environmentally friendly approach to cargo handling at Tokyo Port.
