Tokyo Kisen Co., Ltd. and e5 Lab Inc. have jointly developed the new concept design of “e5 Tug,” electric propulsion harbor tugboat powered by large-capacity battery and a hydrogen fuel cell.
The e5 Tug is a harbor 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 harbor 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.
