Subsea Battery System for Offshore Wind Completes Test Before Deployment

Verlume, a UK-headquartered subsea batteries and power management systems specialist, has put its 500 kWh modular subsea energy storage system to the test in Aberdeen ahead of planned deployment in the Dutch North Sea, where it will become the world’s first grid-forming subsea battery co-located with offshore wind.

Verlume reported on 1 October that it had completed hyperbaric testing of its Orah subsea enclosure at JFD’s hyperbaric testing facility in Aberdeen, representing a major qualification milestone ahead of the system’s planned deployment at the OranjeWind offshore wind farm, being developed by RWE and TotalEnergies off the Dutch coast.

The 500 kWh modular subsea energy storage system is designed to provide autonomous grid support for offshore wind farms.

Orah leverages the latest battery chemistry and is controlled by Verlume’s Axonn power management platform. Together, these technologies are said to create a modular energy storage and autonomous grid-support solution designed to help enable more flexible and resilient offshore energy systems.
