Corvus Pelican Marine Fuel Cell System

Proven fuel cell technology from world leader, Toyota, combined with an inherently gas safe design, make the Corvus Pelican 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 marine hydrogen fuel cell system enables vessels to sustain zero-emission operations for longer periods of time than would be possible using battery power alone.

Extend the range of zero-emission operations using batteries, fuel cells and green fuels

Maritime vessels that recharge often or have enough battery energy storage capacity can achieve zero-emission operations using batteries alone. Unfortunately, for many vessels this is not the case. However, zero-emission operations can be achieved using battery energy storage together with a marine fuel cell system and a green fuel source, such as hydrogen.

With this combination, vessels can maintain zero-emission operations for longer without refueling or recharging. When green hydrogen is used as the fuel source, water is the only system exhaust. The result is an efficient and environmentally friendly power source, ideal for operations in emissions-restricted ports, harbors and zones.


The Corvus Pelican 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 fuel cell and energy storage systems (Corvus CoPilot)
  • Remote performance monitoring capabilities
  • Designed for cost-effective maintenance

Development of the Corvus Pelican Fuel Cell System

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