Why Batteries and Electrical Operation Sustainable energy is one of Iceland's main resources Minimising environmental footprint by reducing fossil fuel Batteries save energy, even without charging from ashore Batteries increase the operational reliability and safety The operation of the ferry is firmer and smoother.

Energy Consumption for one crossing Basis for the operation is 45 minutes crossing and 30 minutes harbour Hybrid Batteries and Diesel Batteries alone

Environmental Impact 14 trips per day 5 months (high season) 10 trips per day 7 months (low season) Yearly energy usage around 5.500 MWh CO 2 emission (kg) 3.573.000 NO x emission (kg) 62.040 CO emission (kg) 9.020 HC emission (kg) Particular matter (kg) 2.820 (Hydro Carbons) 1.240 (Very small particles) SO 2 emission (kg) 2.370 based on SECA requirement s (0,1 %)
