Energy Storage (ESS)
Energy Storage Systems
Battery systems that store energy on board for peak loads, backup and hybrid operation.
Overview
Battery systems that store energy on board for peak loads, backup and hybrid operation.
Large-scale battery banks that store excess energy, reduce fuel consumption and provide backup power — like a giant Powerwall for a ship or data centre.

Capabilities
Key features.
Cell Balancing
Proprietary algorithms maximize cycle life by balancing individual cell states of charge.
Sustainable Chemistry
LFP and next-gen sodium-ion chemistries reduce environmental impact without compromising density.
Cloud Diagnostics
Remote fleet-level monitoring with predictive maintenance scheduling across every installation.
Regulatory context
The rules this system works within.
The international and class requirements that shape how an energy storage system is specified and approved.
- IMOConventionSOLAS Chapter II-1, Part DThe international convention’s requirements for a ship’s electrical installations, including its main and emergency sources of power.imo.org
- IACSUnified requirementIACS UR E26 / E27Cyber resilience of ships and of on-board computer-based systems. Applies to newbuilds contracted from 1 July 2024.dnv.com
