7 Energy storage benefits hybrid operation Engine Specific Fuel Consumption Optimized engine operation Energy storage support operation of engines at optimal specific fuel consumption Reduced engine transients Energy storage will be used to reduce transient loads in engines. Transients will increase fuel consumption and emissions. Maintenance cost will be reduced SFC [%] Engine Load [%] Increased redundancy and efficient operations Power redundancy requirements requires engines to run at low loads. When energy storage is accepted as redundant power the engine will operate more efficient on higher loading and secure back-up in case of trip of engine. 7 Wärtsilä

13 PSV operation with energy storage Annual fuel costs $ 3,000,000 Savings potential 15% Annual savings $ 500,000 Expected payback time 4 years 15% reduction in fuel consumption yearly 20-30% reduction in emissions Short pay-back time (4-5 years) Silent and emission free operation in harbours (using batteries) Can be installed on new builds and as retrofits Support green operations in the oil & gas industry Need incentives to start investment in an industry where the oil companies pays the fuel bill Payback time is based on a new build and an actual operational conditions where the energy storage is used as redundant source and as peak shaving. 13 Wärtsilä

14 DP operation Today- two engines in operation due to redundancy requirements Hybrid operation - one engine and battery in operation Conventional = gas electric operation Hybrid = engine + battery 14 Wärtsilä

15 Folgefonn project low and ZERO emission energy systems DESIGN Renewable energy 15 Wärtsilä Storage of energy QUALIFICATION, TESTING & DEMO Demo ferry - Folgefonn

16 The new flexible, safe and efficient ferry The first ferry that can operate seamless between different modes of operation Diesel electric mode (as today) A multiple of hybrid modes with or without charging from shore (15-25% fuel saving) Pure electrical mode with charging renewable energy from shore (no fossile fuel used) reduce energy cost with more then 50%. 16 Wärtsilä

17 Hybrid ferries flexible and modular design HYBRID (+ PLUG-IN HYBRID) Batteries combined with engine to optimize performance with variable operation profiles ALL-ELECTRIC Batteries used as only power source all the time during operations 17 Wärtsilä
