6 FAQs about [Analysis of energy storage battery safety incidents]

Where can I find information on energy storage safety?

For more information on energy storage safety, visit the Storage Safety Wiki Page. The BESS Failure Incident Database was initiated in 2021 as part of a wider suite of BESS safety research after the concentration of lithium ion BESS fires in South Korea and the Surprise, AZ, incident in the US.

What causes large-scale lithium-ion energy storage battery fires?

Several large-scale lithium-ion energy storage battery fire incidents have involved explosions. The large explosion incidents are due to the deflagration of accumulated flammable gases generated during cell thermal runaways within one or more modules. This leads to damage of battery system enclosures.

Why is a delayed explosion battery ESS incident important?

One delayed explosion battery ESS incident is particularly noteworthy because the severe firefighter injuries and unusual circumstances in this incident were widely reported (Renewable Energy World, 2019).

Are there fires and explosions in lithium battery energy storage stations?

There have also been considerable reports of fires and explosions in lithium battery energy storage stations. According to incomplete statistics, there have been over 30 incidents of fire and explosion at energy storage plants worldwide in the past 10 years.

What are the different types of energy storage failure incidents?

Stationary Energy Storage Failure Incidents – this table tracks utility-scale and commercial and industrial (C&I) failures. Other Storage Failure Incidents – this table tracks incidents that do not fit the criteria for the first table. This could include failures involving the manufacturing, transportation, storage, and recycling of energy storage.

How does the battery industry improve risk reduction measures?

The battery industry continues to engage in R&D activities to improve risk reduction measures. The database includes the cause of failure for each incident, where available. EPRI, TWAICE, and the Pacific Northwest National Laboratory (PNNL) collaborated on an effort to classify the root cause of each incident in the database.
