Lloyd’s Register approves Corvus Energy’s marine battery system

Norway-based energy storage company Corvus Energy has received type approval from the UK-based classification society Lloyd’s Register (LR) for its Dolphin NxtGen Energy marine battery system.

As disclosed, the Dolphin NxtGen Energy design draws on Corvus’ Orca energy storage system (ESS) and features safety measures such as passive single-cell thermal runaway (TR) isolation and a TR gas exhaust system. According to Corvus, it is optimized for both space and weight efficiency, essential elements in vessel design.

The company’s battery management system (BMS) and digital solutions, including remote monitoring and digital twin technology, reportedly, enhance operational safety throughout the battery system’s lifetime.

Fredrik Witte, CEO of Corvus Energy, said: “We are very pleased that the Dolphin NxtGen Energy battery system has now also received type approval from LR, confirming that it meets the high safety standards required in the maritime industry. Achieving LR Type Approval is a major milestone in our work to power a clean future as LR is one of the major class societies and a key player in many segments where the adoption of hybrid and electric solutions are high.”

To note, Corvus Energy has also secured approvals from classification societies Bureau Veritas and DNV and is pursuing additional certifications.

It is worth mentioning that, in 2024, the company received type approval from DNV for its Pelican fuel cell system (FCS), which was developed through the three-year-long H2NOR project. As per Corvus, this is the “first” fuel cell system designed to be inherently gas-safe. The building block of the system is a proton exchange membrane (PEM) fuel cell module from Toyota.

Pelican FCS was launched in 2023, and in 2024, as part of the project APOLO, Corvus was awarded EU funding for the integration of ammonia cracker technology with the Pelican system.
