This is e5, the first fully electric tanker being built in Japan
A new ship powered only by lithium ion batteries it is being built in Japan. At about 60 meters long, it will be the first of its kind to be fully electric. They expect it to sail through Tokyo Bay next year.
After the electrification of cars and attempts on airplanes, the maritime industry seems to be next. Shipbuilders are looking for ways and means to electrify your ships, regardless of the size they are. The tanker e5 is going to be the first of its size to do so.
An electric boat to transport … oil
Ironic or not the purpose of the e5 tanker is to transport precisely what it is fleeing from. The e5 will be operated by Asahi Tanker, a company that provides fuel to refuel the tanks of other cargo ships in Tokyo Bay. The e5 however, even though it will be packed with fuel, it will not use it to move.
Instead of fuel the e5 has a series of lithium-ion batteries with a capacity of 3.5 MWh. According to Corvus Energy (the company that supplies the battery), is about the size of 40 batteries in a Tesla Model S and with this the boat can be powered for “many hours” before having to recharge again. Of course, it does not indicate the loading time it has.
Corvus Energy has some experience in this, over the last few years it has put batteries in dozens of ships around the world. They have especially seen their lucrative business in the Norwegian fjords, where tourist boats have significant restrictions when it comes to emitting CO2 into the environment. Hence we have already seen attempts previously here.
Going back to e5, it is the first offshore tanker to be fully electrified and consequently have zero emissions. If all goes according to plan, it wouldn’t be surprising to see more electrified tankers in the future. The e5 can be a demonstration of how this technology is viable on ships of this caliber. Now, we’ll have to see it in operation first.
Be that as it may and despite its size, not the largest electric boat in the world. Corvus Energy itself is preparing a 10 MWh battery for the AIDAPerla cruise ship, which is expected to carry around 3,300 passengers. The Yara Birkeland is another container ship that is 80 meters long and is expected to be completed this year with its 9 MWh battery.
