The potential of emerging battery technologies to contribute to the decarbonisation of shipping is explored in the latest sustainability technology guidance from ABS.

Emerging Battery Technologies in the Maritime Industry covers the different technologies relevant to maritime applications, giving pros and cons for each and analysing their maturity compared to today’s lithium-ion batteries. Battery technologies covered include Metal-Air, Redox Flow, Ammonia and Solid-State.

Hybrid battery systems can make a significant contribution to reducing vessel emissions but for such systems to be effective, there is a need for efficient and sustainable battery technologies to provide the necessary power. Depending on a vessel’s demands, improved battery technology can not only meet power requirements but also allow for renewable energy to be implemented, potentially further reducing emissions.
