Japanese shipping firm Asahi Tanker Co. has placed an order for the construction of two electrically-powered tankers.

Japanese shipbuilders Koa Sangyou Co and Imura Zosen KK will be in charge of constructing one vessel each, while Kawasaki Heavy Industries will serve as the system integrator for the duo.

The two ships, described as the world’s first zero-emission electric-powered tankers, are slated for delivery in March 2022 and March 2023 respectively.

The two tankers will adopt the “e5 tanker” design developed by e5 Lab Inc, a company set up by Mitsui O.S.K. Lines, Asahi Tanker, Exeno Yamamizu Corporation and Mitsubishi Corporation to build up infrastructure services in the marine shipping industry that focus on electrically powered vessels.

The tankers will be powered completely by large-capacity lithium ion batteries and are slated to go into service as bunker vessels in Tokyo Bay.
