Verlume’s Orah Successfully Completes Landmark Hyperbaric Testing at JFD

3 October 2026

Verlume has successfully completed hyperbaric testing of its Orah subsea enclosure at JFD’s hyperbaric testing facility in Aberdeen, marking a major qualification milestone ahead of the system’s planned deployment in the Dutch North Sea. The programme required hyperbaric test of the largest vessel ever tested at JFD’s site and provided a critical opportunity to demonstrate Orah’s performance under representative subsea pressure conditions before offshore deployment.

Orah is Verlume’s 500kWh modular subsea energy storage system, designed to provide autonomous grid support for offshore wind farms. Its planned deployment will see the world’s first grid-forming subsea battery co-located with offshore wind, demonstrating a new approach to energy storage and power management in the offshore environment. Orah leverages the latest battery chemistry and is controlled by Verlume’s patented Axonn power management platform, which intelligently manages generation, storage and demand. The system is packaged for the demanding subsea environment by drawing on decades of engineering know-how developed within the offshore Oil & Gas industry. Together, these technologies create a modular energy storage and autonomous grid-support solution designed to help enable more flexible and resilient offshore energy systems.
