ABS: Advanced battery retrofits can cut fuel costs and support alternative fuels integration
ABS has highlighted the growing potential for battery retrofits to deliver immediate gains in efficiency, regulatory compliance and emissions reduction across the global fleet. Its latest study, Emerging Battery Technologies in the Maritime Industry Volume II, stresses that advances in lithium-ion and next-generation batteries can be applied not only in newbuilds but also as retrofit strategies on existing vessels.
The analysis identifies the main barriers to wider adoption as safety challenges linked to thermal runaway (TR) and gas emissions. It provides operators with practical strategies for fire prevention, mitigation and rapid response to support safe installation. ABS also points to the need for stronger safety management frameworks as battery retrofits scale up across marine and offshore sectors.
Michael Kei, ABS Vice President, Technology, said: “Batteries offer tangible benefits in marine operations, from cost savings to enabling hybrid propulsion and integration with alternative fuels. Retrofit applications are particularly attractive for owners seeking near-term performance gains while preparing for stricter regulatory regimes.”
The report delivers detailed evaluations of six emerging battery types, alongside guidance for operators planning retrofit projects. ABS continues to offer certification and technical support to ensure retrofit installations are carried out safely and effectively.
