Wärtsilä HY hybrid propulsion system
What is a hybrid marine system? A hybrid system on a ship combines an energy storage system – a vessel battery - and a conventional engine. Its foremost benefit is that it allows the engine to run on optimal load because the battery will absorb many of the load fluctuations and acts as spinning reserve. This saves fuel and reduces GHG emissions.
