Bureau Veritas Marine & Offshore (BV) has called for greater clarity regarding standardized safety regulations that will advance the development of maritime electrification technologies, following the publication of its new technology report, “Maritime Electrification: Maritime Battery Systems and Onshore Power Supply.” 

The report explores how electrification technologies, specifically energy storage systems (ESS) and onshore power supply (OPS) solutions, can support maritime decarbonization strategies.

While OPS benefits from existing international standards, battery systems remain under-regulated, despite growing safety concerns. The risk of thermal runaway incidents within lithium-ion (Li-ion) battery technology poses a serious challenge to crew members. Thermal runaway, a rapid, uncontrollable increase in battery temperature can lead to fires that are difficult to extinguish and poses a significant hazard to crew welfare. Despite the increasing deployment of ESS across the global fleet, current safety guidance remains fragmented and largely nonmandatory. 

Battery adoption is accelerating, with more than 1,000 battery-powered ships in service globally. Meanwhile, OPS systems are already supported by EU regulation, with FuelEU Maritime establishing the mandatory use of OPS systems for container and passenger ships docked at EU ports from 2030, followed by all EU ports with OPS facilities from 2035.

The new BV report follows the International Maritime Organization’s decision in April 2025 to set ambitious emissions reduction targets through 2040. However, current projections indicate the 2030 goals may not be met, prompting renewed focus on all viable low-emission technologies, including electrification. Comprehensive, enforceable international standards are needed to ensure the safe deployment of Li-ion technologies at scale and pace.
