Corvus Energy’s Blue Whale ESS wins DNV type approval

Norway-based energy storage company Corvus Energy has received type approval from classification society DNV for its Blue Whale marine energy storage system (ESS). 

As informed, the DNV type approval confirmed that the large-scale energy storage system complies with the most stringent rules, regulations, and safety requirements in the industry, as defined by the maritime class society.

Specifically, the approval for the Blue Whale ESS includes approval of the production facility for the Corvus Blue Whale product, located in Canada outside of Vancouver.

The Blue Whale ESS is designed specifically for large vessels, like cruise ships, roll-on/roll-off passenger (RoPax) ferries, and service operation vessels (SOV), and vessels that require a large amount of energy. 

The system features optimized energy density and a flexible, modular design architecture, that makes it better equipped to meet the energy demands of large vessels. 

Optimization for energy density enables Blue Whale to deliver more power. This in turn can extend the vessel’s ability to achieve and maintain zero-emission operations, including during transit through emissions-restricted zones and zero-emission port stays, according to Corvus Energy.

“We are very pleased that the Blue Whale ESS design has received type approval from DNV, meeting the highest safety standards in the industry,” said Fredrik Witte, CEO of Corvus Energy. 

“Developing a full family of battery energy storage systems with highly flexible architecture is a clear path towards powering a clean future for shipping. Scalable technology combined with safety and easy integration will help accelerate the transition and make clean energy available to more vessel types.”

More than fifteen Blue Whale orders, cumulatively totaling over 95 MWh, are already confirmed for delivery in 2024, 2025, and 2026.

In addition to securing DNV Type Approval, Corvus Energy is pursuing type approval from ABS, RINA, BV, and Lloyd’s Register for the Blue Whale ESS.

Earlier on, Corvus Energy secured ClassNK’s approval for its marine energy storage system Orca. According to the company, more than 600 vessels and port applications have an Orca system installed worldwide.
