WORKBOATS AND TUGS “e5 Tug” – Electric Tug Powered by Battery
and Hydrogen Fuel Cell Tokyo Kisen Co., Ltd. and e5 Lab Inc. have jointly developed the new concept design of “e5 Tug,” electric propulsion harbour tugboat powered by large-capacity battery and a hydrogen fuel cell.
“e5 Tug” – electric tug powered by battery and hydrogen fuel cell
The e5 Tug is a harbour tug fully electrified and designed to minimize environmental footprint.
The e5 Tug is equipped with a propulsion system running on “e5 powertrain platform”, devised and planned by e5 Lab, which utilizes a large-capacity battery system as a main power source and a hydrogen fuel cell and generator as the auxiliary power source.
This electric propulsion system will ensure sufficient bollard pull and
continuous cruising time necessary for a harbour tugboat which requires a large-capacity power to function. Furthermore, CO2 emission is minimized by incorporating fuel cell.
This joint project is drawing upon knowledge and experience of Tokyo Kisen as a tugboat operator and e5 Lab is undertaking concept planning/development, design, and project management.
The project will proceed by seeking advice from the Ministry of Land, Infrastructure, Transport and Tourism, ClassNK, and others for the regulatory compliance. After the final investment decision the aim is to launch the tug for commercial operations at Yokohama Port and Kawasaki Port in 2022.
