e-Motion Hybrid Propulsion Systems are poised to revolutionize marine propulsion for yachts, offering both Parallel and Serial hybrid options.
These innovative systems are designed to enhance efficiency, reduce emissions, and elevate the onboard experience. Let’s explore the key features of each system and how they will transform life on board yachts.
Parallel Hybrid:
e-Motion’s Parallel Hybrid system is an ideal choice for planning hulls, where speed and performance are crucial.
The system’s electric engines are seamlessly flanged onto the main diesel engines through an integrated clutch mechanism, allowing for flexible power distribution. The setup includes variable speed generators, Lithium-Ion battery packs, and a DC Bus that work in harmony to optimize performance.
• Full Electric-Parallel Hybrid: With a touch of a button on e-Motion’s touchscreen panel, the yacht can transition into Full-Electric navigation mode. In this mode, the clutch disengages, and the power stored in the batteries propels the electric engines. This power is also directed to fully support the hotel load, ensuring maximum comfort for passengers.
• Parallel Hybrid-Diesel Electric: For long-range crossings, the Diesel-Electric Navigation mode comes into play, providing exceptional fuel savings and comfort. The clutch disengages, and variable speed generators supply power through the DC bus. This power is used to slow charge the batteries, feed the hotel load, and energize the electric engines, combining the benefits of both diesel and electric propulsion.
• Alternator Mode-Parallel Hybrid: While the main diesel engines warm up, the yacht can utilize the Alternator mode. By engaging the clutch through the touchscreen panel, the electric engines transform into generators. This setup allows fast-charging of the battery packs and simultaneous support for the hotel load.
• Booster Mode-Parallel Hybrid: When it’s time for fast cruising, the Booster mode enhances the yacht’s top speed. The clutch engages, and variable speed generators kick in to supply power to the hotel load, slow-charge the batteries, and provide an additional boost to the electric engines, thereby increasing the vessel’s performance.
Serial Hybrid:
For displacement and semi-displacement vessels, e-Motion’s Serial Hybrid system offers a unique solution that caters to comfort and efficiency.
• Full Electric Navigation Mode - In this mode, the yacht glides through the water in complete silence. The e-Motion battery packs take charge, powering both the propulsion system and the Hotel-Load with Zero-Emissions. This mode is perfect for serene and eco-conscious journeys.
• Diesel-Electric Navigation Mode: During extended crossings, the Diesel-Electric Navigation mode shines. Variable speed generators take over, supplying power to the hotel load, slow-charging the battery packs, and energizing the electric engines. This setup ensures both efficiency and comfort during long voyages.
In conclusion, e-Motion Hybrid Systems herald a new era in marine propulsion, where efficiency, eco-friendliness, and comfort intersect. By offering versatile options for both planning hulls and displacement vessels, these systems are set to transform life on board yachts of all sizes. As the world embraces the future of electric propulsion, e-Motion is leading the charge towards a cleaner, quieter, and more enjoyable yachting experience.
