  3. 3. © Wärtsilä 4/16/2019 Engine technology seminar - batteryes, storagae, fuel cell and hybrids Internal combution piston engines efficiency Fuelconsumption(/time) Effective Power Blue line – typical diesel cycle behaviour Red curve – typical otto cycle behaviour “Y=aX+b” Smallest possible “powerplant” results in lowest losses 4
  4. 4. © Wärtsilä 4/16/2019 Engine technology seminar - batteryes, storagae, fuel cell and hybrids Hybrid solutions: Replace spinning reserve by ESS (virtual generator), and dimension or operate “power plant” according average load Power available Power need 5

  6. 6. © Wärtsilä 4/16/2019 Engine technology seminar - batteryes, storagae, fuel cell and hybrids Example: Dynamic positioning vessel DP3 When “failing” is not an option a lot of reserve power is kept immediately available for just in case Avarage load if done with spinning reserve can be as low as 15%! 7
  7. 7. © Wärtsilä 4/16/2019 Engine technology seminar - batteryes, storagae, fuel cell and hybrids Fuel cells – the basics • Low temp. (<100 °C) or High temp. (600 to 800 °C) • Efficiencies between 50 and 70% • Can use a multiplicity of fuels: Hydrogen LNG Biogas Ammonia Methanol 8

  9. 9. © Wärtsilä 4/16/2019 Engine technology seminar - batteryes, storagae, fuel cell and hybrids Efficiency • High efficiency over a wide load range • Lifetime is influenced by thermal stress  Stable load preferred 10

  11. 11. © Wärtsilä 4/16/2019 Engine technology seminar - batteryes, storagae, fuel cell and hybrids Summary • Batteries as energy carrier for ships are limited to short range and limited power applications • Replacing spinning reserve with instantly available power from batteries enables engines to be operated at higher load enhancing overall operational efficiency, reduce emissions and reduce maintenance cost • Fuelcells have interesting features as power convertor. Price development will determine if and when they will be a commercial viable alternative to piston engines. 12
