Corvus Blue Whale
The Corvus Blue Whale design is a result of the knowledge gained from having the largest global installed base of ESS solutions combined with our industry leading research and development capabilities.
Low weight and low total system volume have been key design criteria, along with keeping the unsurpassed energy safety features from the Corvus Orca ESS resulting in world leading energy density in a battery room with minimal service aisle requirements.
Applications
The Corvus Blue Whale ESS differs from other ESS technologies available in the market in that it is specifically designed for use in large vessels where the operational profile calls for slow charge and discharge rates and requires the ability to sail emission-free over longer periods of time, including during emission-free during port stays.
Blue Whale is ideal for applications in need of a large amount of energy at a cost effective kWh price. The system has been developed with larger installations (>10MWh total system energy) in mind.

Fuel Cell Systems
Extending zero-emission operations
Vessels that can charge often or have enough energy storage capacity, can operate zero-emission on batteries alone. For other vessels, we need to extend the range by adding green fuels and a fuel cell system.
Corvus Energy drives innovation for zeroemission transport one step further with its development of the Inherently Gas Safe Fuel Cell System to its well-established marine battery portfolio.
Using the well-proven hydrogen fuel cell technology from Toyota, already used in cars around the world, and adding a higher level of safety, makes this an advanced marine fuel cell system with high integrity.
Batteries and fuel cells are best friends
Battery energy storage systems handle load variations perfectly, and fuel cell systems perform best at stable load conditions. Together, they are ideal partners.
Corvus Energy is developing CoPilot, a real-time advice system designed to optimize power distribution between the battery energy storage and fuel cell systems.
Fuel Cell Systems 18 Corvus Energy
What is a marine fuel cell system
A marine fuel cell system can be used as a range extender for various types of vessels, providing an efficient and environmentally friendly power source.
Fuel cells are electrochemical devices that convert the chemical energy from a fuel, such as hydrogen or ammonia, into electricity through a chemical process.
In the context of range extension, Corvus Energy marine fuel cell systems, used in combination with battery energy storage systems, provide additional power when needed. This allows vessels to operate producing zero-emissions for longer periods of time without refuelling or recharging.
Corvus Pelican Fuel Cell System
The Corvus Pelican Fuel Cell System (FCS) is specifically built to be the perfect range extender for near shore and short sea vessels that are not able to reach zero -emission operations on batteries alone. The system combines well-proven technology from Toyota with the inherently gas safe design, which makes this one of the safest and most advanced marine fuel cell systems available.
Applications
The Corvus Pelican FCS is ideal for zero-emission operation 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.
