Fuel Flexibility for ships with dual fuel engines

  1. 1. FUEL FLEXIBILITY FOR SHIPS WITH DUAL FUEL ENGINES 25.09.2019 DNV GL Alternative Fuels Online Conference Sebastiaan Bleuanus General manager research coordination & funding Wärtsilä Marine Business
  2. 2. LNG: A KEY ENABLER FOR IMO 2050
  3. 3. © Wärtsilä Document ID Revision Base year 2015 2020 2025 2030 2035 2040 2045 2050 Yearly Fleet Emissions (CO2 equivalent) Medium growth scenario 40% emission improvement DATA, TECHNOLOGY AND THE ENERGY SOURCE WILL TAKE US TO 2030 Use of data in operation • Increased fleet efficiency • Increased asset utilisation Energy storage and savings technologies • Energy production optimisation • Energy consumption optimisation • Hybridisation (batteries, fuel cells, etc) Energy source • Fossil LNG • Biofuel blends • Renewable energy utilization (wind, solar, etc.) Fleet emission impact of -40% emissions per vessel SUSTAINABLE FUELS AND ADVANCED TECHNOLOGIES WILL TAKE US TO 2050 • Bio/synthetic fuels for the combustion engine • Waste heat recovery • Carbon capture • Carbon credits -50% GHG by 2050 for the whole fleet remaininggap Data adapted from CE Delft Proprietary data; same modelling methodology as used in the 3rd IMO GHG study A SUSTAINABLE FUTURE REQUIRES CLEANER FUELS One ship’s lifetime…

  6. 6. © Wärtsilä Document ID RevisionCopied with pride from: DNV GL, MARITIME Forecast to 2050 (2019 version) WE HAVE TO START RIGHT NOW! TO MEET THE TARGET IN 2050 WE NEED TO FOCUS ON AVAILABLE TECHNOLOGIES AND ALSO DEVELOP ALTERNATIVES
  7. 7. © Wärtsilä Document ID Revision COMBUSTION ENGINE + BIO/SYNTHETIC LNG COMBUSTION ENGINE + LNG AS A FUEL IS A FUTURE-PROOF SOLUTION TO 2030 WE HAVE TO START RIGHT NOW! BRINGS YOU EASILY TO 2050 WITHOUT ANY ADAPTIONS ON YOUR ENGINE ARRANGEMENT LNG as Marine Fuel • A clean fuel, no after-treatment needed for emission compliance • Infrastructure in place/maturing • Shifting from diesel to fossil LNG reduces CO2 emissions by 7 to 21% • Reliable engine technology. More than 2100 engines > 26.000.000 running hours • Providing an infrastructure and the pathway for renewable fuels • Easy to blend with BioLNG and Synthetic LNG
