It is powered by a massive lithium-ion battery supplied by Corvus Energy and developed by e5 Lab, a consortium set up by Japanese partners to build up infrastructure services in the marine shipping industry that focus on electrically powered vessels.

The 62-meter-long vessel has a tank capacity of 1,280 cubic meters. Specifically, the tanker achieves zero emissions of CO2, NOx, SOx, and particulates, reducing environmental impact. In addition, reduced noise and vibration will create a more comfortable work environment for the crew members and limit noise pollution in the bay and its surroundings.

The revolutionary vessel is the first of two all-electric vessels to be built from the e5 Lab initiative. The second ship, which is under development by Imura Shipyard Co., Ltd. in Japan, is expected to be completed by March 2023.
