Even though there is much ongoing effort to help the environment by making cars emissions-free, oil tankers and cargo ships are responsible for massively contributing to the planet’s pollution. When transitioning to cleaner mobility, it’s important to include ships and tankers that emit the same amount of pollution as millions of cars put together. That’s why the world’s first all-electric oil tanker is currently being built with a huge 3.5 MWh battery pack. The tanker is being constructed by a consortium of seven large Japanese companies.
Asahi Tanker announced that it has ordered two of the new electric tankers and plan on making them operable in March 2022 and March 2023. The most important feature of the all-electric oil tank, its massive battery pack, was recently ordered from Corvus Energy. What’s more interesting is that the extremely high battery capacity can be used for emergency services in Tokyo if a natural disaster occurs.
Overall, the 62-meter ship has a tank capacity of 1,300-meter3 and a speed of 11 knots. It’s designed to reduce noise and vibration, making it more comfortable for workers while limiting noise pollution in the bay area. The primary goal of the vessels is to deliver fuel for other vessels. At half power (300 kW), the batteries could last for approximately 10+ hours.
Asahi Tanker says both tankers are expected to achieve zero emissions of CO2, NOx, SOx, and particulates thanks to the all-electric core energy system, which dramatically reduces their environmental impact.
In September 2020, Kawasaki Heavy Industries received the ship’s propulsion system contract. It allows the 3,480 kWh Orca ESS from Corva Energy to be integrated.
Electric ferries are already in service, and the Roald Amundsen, a 500-passenger hybrid cruise ship that runs on electric power, was revealed in 2019.
