3 The new ferry Length Breath Draught Car capacity 71,80 m 15,10 m 2,85 m 75 PCU Passenger capacity 540 Shaft Power Generator power Battery Capacity Speed kw kw kwh 15,6 knots

4 References to ferries and battery operation Helsingør Helsingborg Design of ferries and harbours Rødby Puttgarden installation of batteries /operation Spodsbjerg Tårs Design of ferries and harbours Gedser Rostock Design of ferries and operation

5 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.

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

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

8 Engine Room - Arrangement and Suppliers Main Switchboard Marine Electric production & Propulsion thrusters Batteries Shore Connection

9 The Core The Switch Board Main Switchboard: 1000 V DC, Variable voltage Generators: 3 x 690 V AC, Variable frequency Propulsion thrusters: 3 x 690 V AC, Variable frequency Power consumers: 3 x 690 V AC, 50 H / 3 x 230 V AC, 50 H Shore Connection: 3 x 600 V AC Marine

10 Energy Storage System - Batteries (ESS) One Battery 5,65 kwh One Rack 22 batteries, 124,3 kwh Total Battery Capacity 24 racks 2983,2 kwh Typical Voltage DC VDC Typical state of charging 50% - 90%

11 The Propulsion Pulling Thrusters Rolls Royce Azipull 5 bladed fixed pitch propeller Power Output 2 x 1700 kw, Variable speed Rotation 2 RPM (12 O per second)

12 Elektrical Production - Diesel Engines and Generators Electrical Production 3 x 1,350 kw, Variable frequency Emission Class Tier III, EPA

13 Shore Connection Ferry Charger Capacity kw 30 minutes Charging kwh Fully Automatic Charging in both harbours

14 Batteries save energy even without shore connection Spinning reserves not needed The diesel engine can run at its optimum point Variable speed 205 g/kwh % Fixed speed 205 g/kwh 100% 350 g/kwh 20%
