Corvus Energy deploys large-scale energy storage systems (ESS) using advanced lithium-ion battery systems proven economical, safe, and reliable in a range of challenging maritime and transportation applications.

More than 50% of the world’s hybrid and zero-emission vessels are equipped with Corvus Energy Storage Systems. They have more than 350 MWh deployed in 500+ projects and more than 3 500 000 operating hours.

ESS Products:

• Corvus Blue Whale: The Corvus Blue Whale Energy Storage System is a ESS specifically designed to meet the large energy requirements of emission-free operation over longer periods of time
• Corvus Orca Energy: Orca Energy is ideal for applications that are in need of both energy and a high amount of power, moving large amounts of energy at an inexpensive lifetime cost per kWh.
• Corvus Dolphin Energy: The Dolphin Energy ESS is specifically designed for lightweight applications.The flexible design of the Dolphin Energy allows the system to be stacked in various directions enabling high space efficiency in compact installations.
• Corvus Dolphin Power: It is specifically designed for lightweight applications. The flexible design of the Dolphin Power allows the system to be stacked in various directions enabling high space efficiency in compact installations. Dolphin Power is ideal for high-speed vessels that need to boost propulsion to reach max speed, or vessels that must recharge the batteries quickly and often.
• Corvus Moray Power: This is a highly advanced battery system for demanding subsea environments. This Energy Storage System is ideal for systems performing active heave compensation, buffer stations, or high power rated actuators.
• Corvus Moray Energy: This Energy Storage System is ideal for subsea energy banks for long-term power supply with very low self-discharge rated actuators.
• Corvus Blue Marlin: It is designed for use in any application in need of short peaks of high power. It has industry-leading design with no manual connections, enhanced reliability and high safety levels.
• Corvus BOB Container: It is a standardized, class-approved, modular battery room solution available in 10-foot and 20-foot ISO high-cube container sizes. The complete energy storage system (ESS) comes with battery, battery monitoring system (BMS), HVAC , TR exhaust, and firefighting and detection system. The “Plug and Play battery room” simplifies integration into any system integrator’s power management system on board a ship.

For all installations, Corvus provides a Life Cycle Service Program commencing after the Customer Acceptance Test (CAT). The Life Cycle Service Program includes:

• 24/7 technical support
• Support on alarms and incidents handling according to agreed SLA standards
• Required QHSE and incident handling training programs for vessel crew and other resources
• A secure Vessel Information Portal with restricted access and personal credentials
• Continuously monitor and report battery condition in the vessel information portal
• ESS specific documentation and logs are accessible through the Vessel Information Portal
• Inventory list of spares and online spares requests
• Alternative options for battery End of Life/recycling
• Annual expert based advisory report on system usage and performance to achieve estimated life span

Adding fuel cells to battery technology is an important part of the energy transition to reduce emissions from shipping. H2Nor is a project initiated by Corvus Energy, Toyota and other partners to fast-track the development and production of sustainable and scalable Maritime Hydrogen Fuel Cell Systems.

H2NOR: Development and demonstration of a maritime hydrogen fuel cell system with performance ranging from 320 kW to 10 MW, based on world leader Toyota fuel cell technology. Goal: Scalable product ready for production in Bergen and commercial phase.

• End of project 2023
• Commercial deliveries start: 2024

Corvus Energy sells the different ESS products listed above and provides a range of aftermarket services – from commissioning, all through the battery lifetime, to decommissioning and recycling. They offer tailor-made service agreements to each customer’s specific needs, covering the entire lifecycle of the product.

Corvus Energy is a manufacturer of Energy Storage Systems (ESS) based on lithium NMC technology. More than 50% of the world’s hybrid and zero-emission vessels are equipped with Corvus Energy Storage Systems. They have more than 350 MWh deployed in 500+ projects and more than 3 500 000 operating hours. This gives them experience and valuable feedback, that enables them to continuously improve their products and services to meet the highest standards, and at the same time push boundaries for how energy storage is used to optimize energy consumption onboard ships to save costs and emissions.

Corvus is spearheading a collaboration with various partners to develop and produce modularised and cost-effective PEM (Proton Exchange Membrane) fuel-cell systems for the international marine market. Their new dedicated fuel cell division will design and certify the marine fuel cell system using the Toyota fuel cell technology as a building block for larger systems. Also, a specific marine control system uniting the battery and fuel cell operation will be developed for easy integration with power management systems from a range of system integrators.

The Corvus Energy product portfolio covers a range of ESS solutions suitable for various applications. As the requirements for every project are different, there is no “one-fits-all” when it comes to battery systems. Corvus Energy has therefore developed a wide range of products, ensuring that they can offer the most suitable solution to any application.
