Serial Hybrid: Single Electric Motor with Generator Power & Energy Storage

This serial hybrid system uses a single electric motor and can both generate power and store energy. The system optimizes fuel consumption with a constant-speed generator engine. It’s best suited for vessels (e.g., military vessels, ocean-going vessels, ferries, and large yachts) operating in restricted areas and zero-emission zones.
