‘e5 Consortium’ Established to Promote Zero-Emission Electric Vessel;
~Project Encompasses Development, Realization, Commercialization~

TOKYO — Seven companies—Asahi Tanker Co., Ltd., Idemitsu Kosan Co., Ltd. (trade name: Idemitsu Showa Shell), Exeno Yamamizu Corporation, Mitsui O.S.K. Lines, Ltd., Tokio Marine & Nichido Fire Insurance Co., Ltd., Tokyo Electric Power Company, and Mitsubishi Corporation—today announced establishment of the “e5 Consortium,” with the goal of establishing new ocean shipping infrastructure services through various initiatives to develop, realize, and commercialize zero-emission electric vessels.

An Electric Vessel from Japan:The World’s Cleanest, Smartest Vessel

Coastal shipping in Japan faces structural issues such as a shortage of mariners due to the aging of the seagoing workforce, not to mention the aging of the vessels. In addition, the ocean shipping industry has urged the coastal shipping industry to reduce emissions of greenhouse gases (GHGs) as one of Japan’s measures to address climate change. The seven e5 Consortium corporate members are focusing their attention on fulfilling the potential of electric vessels to solve these urgent issues. The consortium aims to establish a platform that offers innovative ocean shipping infrastructure services based on electric vessels bringing to bear the strength, technological know-how, networks, and other advantages of each member company.

As the first phrase of the project, the consortium plans to launch the world’s first zero-emission electric tanker, powered by large-capacity lithium ion batteries, in March 2022 (Note 1). e5 Lab. Inc. will serve as the executive office of the e5 Consortium. (Note 2)

The e5 Consortium will promote the sustainable growth of coastal shipping in Japan and contribute to the nation’s social and economic development by providing added value to the coastal shipping industry through the development and introduction of advanced vessels.

What is ‘e5’?

A provider of safe, reliable, and high-quality transport service, based on the realization of five core values: “electrification,” “environment,” “evolution,” “efficiency,” and “economics.”
