ELECTRIC PROPULSION SYSTEMWärtsilä Low Loss HybridThe introduction of Wärtsilä Low Loss Hybrid (LLH) and its integrationwith a conventional diesel or dual-fuel engine generating sets, offerssignificant efficiency improvement by running the engines on optimalload and absorbing many of the load fluctuations through batteries.The system is designed and integrated to optimise the overall operationof the vessel.The power and energy capacity of the battery should be suitableto allow the engine to run for most of the time on optimal loads. Thesystem is designed and integrated to optimise the overall operation ofthe vessel. A key element is hybrid control algorithms for load sharingbetween units and efficient power and energy management.Wärtsilä Low Loss Hybrid ensures substantial reduction inemissions, and supports a sustainable operation with different fuels.The yearly fuel savings have proven to be between 10–20% dependingon type of engines and configurations.31
