Fleetzero: Integrated Electric Propulsion for Large-Scale Shipping
Fleetzero takes a different approach than traditional battery suppliers. Instead of just selling battery modules, Fleetzero builds complete electric and hybrid propulsion systems designed for large cargo ships. By focusing on the entire powertrain and developing unmanned vessel technology, Fleetzero aims to make electric shipping viable for long-haul routes that were previously restricted to heavy fuel oil.
- End-to-end propulsion systems rather than standalone battery packs
- Designed specifically for large-scale cargo and merchant vessels
- Development of unmanned cargo vessel technology to optimize efficiency
- Focus on long-range viability through system-level optimization
