With the advantages of high energy density, short response time and low economic cost, utility-scale lithium-ion battery energy storage systems are built and installed around the world. However, due to the thermal runaway characteristics of lithium-ion batteries, much more attention is attracted to the fire safety of battery energy storage systems.
The challenges of providing effective fire and explosion hazard mitigation strategies for Battery Energy Storage Systems (BESS) are receiving appreciable attention, given that renewable energy production has evolved significantly in recent years and is projected to account for 80% of new power generation capacity in 2030 (WEO, 2023).
Fire accidents in battery energy storage stations have also gradually increased, and the safety of energy storage has received more and more attention. This paper reviews the research progress on fire behavior and fire prevention strategies of LFP batteries for energy storage at the battery, pack and container levels.
Since a large amount of energy is stored in the energy storage station in the form of chemical energy, once this energy is released in the form of heat and fire, it will cause serious damage. For example, in 2024, three LFP battery energy storage station fire accidents occurred in Germany within three months .
In total, more than 180 MWh were involved in the fires. For context, Wood Mackenzie, which conducts power and renewable energy research, estimates 17.9 GWh of cumulative battery energy storage capacity was operating globally in that same period, implying that nearly 1 out of every 100 MWh had failed in this way.1
In 2019, EPRI began the Battery Energy Storage Fire Prevention and Mitigation – Phase I research project, convened a group of experts, and conducted a series of energy storage site surveys and industry workshops to identify critical research and development (R&D) needs regarding battery safety.
This study adopts a "mechanism-assessment-prevention and control" research framework to systematically analyze the causes and evolution mechanisms of fire and explosion accidents
