Video: Subsea battery storage for offshore renewable energy systemsS. Himmelstein | January 11, 2023
A scalable, modular battery energy storage system with integrated intelligent energy management, for offshore wind or wave energy applications is under development by U.K.-based Verlume. Designed for the harsh subsea environment, the Halo system is engineered to provide a reliable, uninterrupted power supply predominantly for seabed use.
The fully rechargeable energy storage solution can be integrated with marine renewable energy converters to create zero-emission power systems. Halo contains state-of-the-art lithium-ion battery technology that provides maximum energy density, safety and durability, and together with Verlume’s Axonn intelligent energy management system autonomously maximizes the available energy in real-time. Halo is also envisioned to provide regulated DC supply to hydrogen electrolyzers on offshore platforms or within turbines.
Verlume and Oasis Marine Power are collaborating to demonstrate the potential of in-field energy storage and charging infrastructure for crew transfer vessels. The project partners will evaluate the use of the Halo and Axonn intelligent power conditioning and management systems and a powered mooring station to recharge batteries on electrically powered vessels.
