Mitsui E&S, an engineering company in Japan, has introduced a demonstration of cargo handling equipment powered by hydrogen fuel cells at Yokohama Port. By replacing the diesel engine generator in one of its Rubber Tired Gantry Cranes with a hydrogen fuel cell pack, the company aims to reduce carbon emissions and support carbon neutrality at the port. This initiative is part of an on-site demonstration project at the Minami-Honmoku Pier Container Terminal, showcasing the environmental benefits of utilizing hydrogen fuel in port operations. Mitsui E&S's long-standing efforts in developing hydrogen fuel-based solutions highlight its commitment to sustainability and innovation in the engineering sector. The company's near-zero emission RTG model, featuring a larger lithium-ion battery, is designed for future conversion to zero-emission operation once hydrogen infrastructure is in place. This project signifies a significant step towards a cleaner and more sustainable approach to cargo handling in port operations.
