Japan to build first battery-powered tanker
Tokyo-based Asahi Tanker plans to launch the world’s first fully electric tanker in 2022.
The 60-meter coastal vessel, called the e5, will ironically carry diesel fuel to fuel other cargo ships in the bay. Absolutely all of its systems will be powered by lithium-ion batteries with a total capacity of 3.5 MWh. Powerplant supplier Corvus Energy claims that this amount of energy will be enough for the tanker for “many hours” of operation without recharging at the coastal station.

Switching ships to all-electric power is driving the development of battery technology, lowering the cost of battery packs and regularly reducing the permissible levels of carbon dioxide emissions into the atmosphere. According to the developers, the emerging infrastructure will in the future be scaled for larger ships.
However, cargo ships crossing the ocean will most likely never be able to run on battery power alone due to their low energy intensity per volume. Therefore, by 2023, the company plans to produce a large system, combined with hydrogen fuel cells.
We also previously reported that a Swedish consortium plans to commission a 200-meter wind-powered transatlantic cargo ship by 2024.
