Electric ferries between Sweden and Denmark
In November, Swedish ferry operator HH Ferries Group officially inaugurated the Tycho Brahe and the Aurora (built in 1991 and 1992 respectively) as the world’s largest battery-powered passenger ferries on the high-frequency route between Helsingborg and Helsingör.
In each port, automatic land-based charging stations enable efficient charging of each vessel’s 640 batteries within a few minutes. The batteries are located in containers on top of the ferries along with two deckhouses for transformers, converters and cooling systems. The battery power of each ferry is 4,160 kWh. Although planned to run full time on battery power, the two vessels’ quartets of diesel engines are retained on board as back-up to the battery systems.
