That’s a nice development. But the article fails to mention which kind of battery the vessel will use, which I thought was the main reason we didn’t have these kinds of ships yet.
19600 kWh of stored energy is about equivalent to 7 ton of diesel when burnt in diesel engine with 25% thermal efficiency
"Fuel consumption by a containership is mostly a function of ship size and cruising speed, which follows an exponential function above 14 knots. For instance, while a containership of around 8,000 TEU would consume about 225 tons of bunker fuel per day at 24 knots. At 21 knots, this consumption drops to about 150 tons per day, a 33% decline."
"The vessel is equipped with 10 container-shaped power units with a total power supply capacity of about 19,600 kilowatt-hours."
