19 Hybrid system configuration A flexible and efficient energy system with energy storage FUEL SYSTEM ENGINE GEN-SET NEW POWER ENERGY STORAGE HEAT RECOVERY POWER GRID & HYBRID CONTROL ENERGY FROM SHORE HOTEL LOAD PROPULSION 19 Wärtsilä 21 May 2014 E&P Hamburg

20 Energy storage benefits Engine Specific Fuel Consumption 125 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. 20 Wärtsilä 21 May 2014 E&P Hamburg

24 Oppsummering Hvor går utviklingen? Bruk av LNG som drivstoff er velprøvd teknologi fra offshorefartøy Gir ca 25 % reduksjon i CO 2 utslipp Utfordring ved introduksjon i fiskefartøy er øket byggekostnad og usikkerhet rundt fremtidig gasspris. Optimalisering av skrog vil kunne gi ytteligere 5-10% reduksjon av drivstofforbruk og CO 2 utslipp Hybride maskinerisystem med energilagring har et potensiale på 15-20% reduksjon av CO 2 utslipp. 24 Wärtsilä 21 May 2014 E&P Hamburg
