Analysis of the cause of the explosion at the guyana energy storage station

Do container type lithium-ion battery energy storage stations cause gas explosions?

Here, experimental and numerical studies on the gas explosion hazards of container type lithium-ion battery energy storage station are carried out. In the experiment, the LiFePO4 battery module of 8.8kWh was overcharged to thermal runaway in a real energy storage container, and the combustible gases were ignited to trigger an explosion.

What is the explosion hazard of battery thermal runaway gas?

The thermal runaway gas explosion hazard in BESS was systematically studied. To further grasp the failure process and explosion hazard of battery thermal runaway gas, numerical modeling and investigation were carried out based on a severe battery fire and explosion accident in a lithium-ion battery energy storage system (LIBESS) in China.

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).

What happens if a combustible gas explodes in a battery module?

Considering that gas explosion may cause thermal runaway of battery module in the actual scene, the existence of high-temperature zone may be longer and the temperature peak may be higher. After the combustible gas got on fire, the gases volume expanded by high-temperature compresses the volume of the surrounding gases.

How many fire and explosion accidents have happened in EES systems?

However, in the past 10 years, there have been 32 major fire and explosion accidents in EES systems around the world, including three fire accidents in EES systems in China , such as the Beijing energy storage station fire accident in April 2021.

Can Li-ion battery modules simulate gas explosion hazards?

In a recent study, Jin et al. (48) developed a CFD simulation of gas explosion hazards within a container-type ESS comprising Li-ion battery modules.
