Two ferries that will sail to Denmark and Sweden will use electric powered propulsion by the end of 2017. The Öresund Dry Docks, in Landskrona, Sweden, have been selected to modernize the two ferries. M/F Tycho Brahe and M/F Aurora will be equipped with a 4.16 MW battery during February of 2017. When the batteries are empties, they will be charged at stations, which charge about 1200 kWh in a very short time period. The ferry is charged when it enters port. During the 20 active minutes between the ports, the batteries are depleted by about 30% of their capacity. The full capacity of the batteries on each ferry amounts to 4,160 kWh. The ferries will operate between Denmark and Sweden, using only battery power, and will transport about 7.4 million passengers and 1.9 million vehicles annually.
