How Is Lusben Transforming Yacht Propulsion with Electric and Battery Tech?

Lusben has spearheaded multiple yacht refits integrating electric propulsion, including hybrid conversions for 40m+ vessels. Their work focuses on replacing diesel gensets with modular battery systems, such as the refit of “Project Thunderball,” which reduced emissions by 60%. Partnerships with Siemens Energy and Corvus Energy ensure cutting-edge solutions for torque efficiency and energy density. Recent advancements include the “Neptune Hybrid Initiative,” where Lusben retrofitted a 52-meter expedition yacht with 1.2MWh battery capacity, enabling zero-emission operation in marine protected areas. The system combines axial flux motors with AI-driven power allocation, dynamically balancing hotel loads and propulsion demands. This project alone has eliminated 380 tons of annual CO₂ emissions while maintaining transatlantic range capabilities through optimized energy routing algorithms.

Which Battery Technologies Does Lusben Prioritize?

Lusben utilizes lithium-ion phosphate (LFP) and solid-state batteries for marine applications, emphasizing thermal stability and cycle life. Their 2023 collaboration with MG Energy Systems introduced adaptive battery management systems (BMS) that optimize charge/discharge rates in saltwater environments. Case studies show a 35% improvement in energy retention compared to traditional AGM batteries.

How Does Lusben’s Approach Differ from Competitors?

Unlike Feadship or Amels who focus on new builds, Lusben specializes in retrofitting pre-2010 yachts using modular “E-Pod” systems. These self-contained propulsion units can be installed in 14 days versus 6-month drydock periods for full rebuilds. Their patent-pending capacitor arrays also handle 800V rapid charging without grid infrastructure upgrades. The E-Pod’s plug-and-play design allows owners to incrementally upgrade power systems – a 2024 retrofit of the 45m M/Y _Aurora_ saw three E-Pod units installed sequentially during routine maintenance periods. This phased approach reduces upfront costs by 40-60% compared to competitor solutions. Lusben’s proprietary docking interfaces enable seamless integration with legacy shaftlines, preserving original propulsion geometry while boosting efficiency through regenerative braking capabilities.

What Safety Protocols Govern Battery Installations?

All battery compartments feature MIL-STD-810H certified containment vessels with triple-layer thermal runaway shielding. Lusben’s naval architects employ finite element analysis to predict stress points, integrating seawater-cooled busbars that maintain temperatures below 40°C even during rapid discharge cycles. Emergency jettison systems can isolate batteries in <0.8 seconds during faults.

“Lusben’s modular retrofit approach is disrupting marine electrification,” says Redway’s Lead Naval Engineer. “Their patented battery swap system lets owners gradually phase in electrification – you can start with 200kWh modules and scale to 2MWh without redesigning the entire power architecture. It’s like LEGO for marine energy transition, solving the ‘stranded assets’ dilemma for legacy yacht fleets.”
