MITSUI E&S Co., Ltd. has replaced the conventional diesel engine generator set installed on a near-zero-emission Rubber Tired Gantry Cranes (RTG*) which MITSUI E&S delivered to Utoc Corporation (Representative Director and President: Nobuo Shiotsu; hereinafter “Utoc”) at the Yokohama Port Minami-Honmoku Pier Container Terminal with a hydrogen fuel cell power pack.
For many years, MITSUI E&S has been developing cargo handling equipment utilizing hydrogen fuel, laying the foundation for achieving zero emissions at ports. The RTG, which MITSUI E&S provided technical support for and retrofitted, is now being used in Utoc’s “on-site demonstration project for cargo handling equipment powered by hydrogen fuel,” operating as a zero-emission cargo handling machine fueled solely by hydrogen at the Minami-Honmoku Pier Container Terminal. This initiative enables CO₂ emission reduction at ports and contributes to achieving carbon neutrality in port operations.
The hydrogen fuel cell power pack is inside the red frame.
MITSUI E&S will further promote technological development aimed at reducing the environmental impact of ports through the provision of cargo handling equipment products and services powered by hydrogen fuel. MITSUI E&S is committed to contributing to the realization of a safe and efficient carbon-neutral society while striving to build a sustainable future.
※1 Near-Zero Emission Type:
The near-zero emission type is designed with the premise of retrofitting to hydrogen fuel cells. It is equipped with a larger lithium-ion battery compared to the current hybrid model, allowing for the downsizing of the diesel engine. This model enables an easy transition to zero-emission operation once hydrogen supply infrastructure is in place.
