Corvus Energy Pelican Fuel Cell System

The Corvus Pelican Fuel Cell System (FCS) combines well-proven fuel cell technology from world leader, Toyota, with an inherently gas safe design, making it one of the safest and most advanced marine fuel cell systems ever developed.

Built to be the perfect range extender for near shore and short sea vessels, the Corvus Pelican Fuel Cell System enables vessels to sustain zero-emission operations for longer periods of time than would be possible using battery power alone.

Vessels that can charge often or have enough energy storage capacity can achieve zero-emission operations using only batteries. For other vessels, the range of zero-emission operations can be extended by adding green fuels and a fuel cell system.

Corvus Energy marine fuel cell systems, used in combination with battery energy storage and a green fuel source such as hydrogen, extend the period that vessels can operate at zero-emission levels without refueling or recharging. When used with hydrogen, water is the only system exhaust, perfect for operations in emissions-restricted harbors and protected areas.


The Corvus Pelican FCS is ideal for zero-emission operations onboard ships that go on routes where hydrogen supply is available. The system can serve as a main power source or an additional power source. Typical vessel-types are:

  • Container feeder vessels
  • Service operation vessels
  • Platform supply vessels
  • Ro/Ro – Ro/Pax
  • Ferries
  • Tugboats
  • Smaller cruise vessels
  • Coastal/ regional transport


  • Built specifically for marine applications
  • Inherently gas safe
  • Flexible and modular design
  • Scalable to meet any power demand
  • Compatible with next generation fuel cell modules
  • Realtime advisory system to optimize power distribution between the FCS and ESS (CoPilot)
  • Remote performance monitoring capabilities
  • Designed for cost-effective maintenance

The Corvus Pelican Fuel Cell System is commercially available for delivery from 2024, with selected pilot projects and type approval scheduled in 2023. The product is under development as part of the H2NOR project, a joint collaboration between Corvus Energy, Toyota and other partners.
