In 2018, battery operations were inaugurated on ØRESUNDSLINJEN's two ferries, Aurora and Tycho Brahe. With the help of the latest in battery and automation technology, these two older ferries were converted into some of the world's most high-tech and sustainable ferries.

A fully automated, laser-guided robotic arm connects to the ferries to charge them every time they are in port. In just 8 minutes, the batteries are charged with enough electricity to last a twenty-minute crossing, ensuring the ferries can maintain their frequent sailing schedule.

The ferries are charged with "green electricity" from non-fossil sources such as wind, water, and solar power, completely eliminating all direct emissions during the battery-powered journeys. Consequently, ØRESUNDSLINJEN’s direct emissions from the ferries can be reduced by a remarkable 65%.
