Asahi Tanker, a Japanese shipping firm, has launched and named the first of two next-generation all-electric tankers that will be delivered in 2020 as reported by Offshore Energy.
Ceremony
On December 22, 2021, the event was conducted at the Koa Sangyo shipyard in Marugame City, Kagawa, Japan.
The new build, dubbed Asahi, is set to enter service as a bunker vessel in Tokyo Bay in March 2022.
It is powered by a huge lithium-ion battery provided by Corvus Energy and built by e5 Lab, a collaboration formed by Japanese partners to develop infrastructure services for the maritime shipping industry focusing on electrically-propelled vessels.
The tanker, in particular, emits no CO2, NOx, SOx, or particulates, lowering the environmental effect. Reduced noise and vibration will also provide a more comfortable working environment for crew members while also reducing noise pollution in the harbour and its environs.
In the event of a natural calamity in Tokyo, the vessel’s battery power will be made available to emergency services. e5 Lab and Asahi Tanker were the first to propose this concept.
