MITSUI E&S Co., Ltd. has initiated an on-site operation demonstration of cargo handling equipment powered by hydrogen fuel cells at Yokohama Port. By replacing conventional diesel generators with hydrogen fuel cells on Rubber Tired Gantry Cranes (RTG), Mitsui E&S has created a near-zero-emission type of equipment that enables zero-emission operations at ports. This project, in collaboration with Utoc Corporation, showcases the potential for hydrogen fuel in reducing CO₂ emissions and contributing to carbon neutrality in port operations. Mitsui E&S is dedicated to developing more hydrogen-powered cargo handling equipment to support environmental sustainability in port operations and work towards a carbon-neutral society. The introduction of a larger lithium-ion battery in the near-zero emission type facilitates an easy transition to zero-emission operation once hydrogen infrastructure is in place. This technological advancement marks a significant step towards reducing the environmental impact of port operations and building a sustainable future.
