Beijing-hong kong-macao energy storage container caught fire

What caused a lithium-ion energy storage system explosion in China?

The cause of a lithium-ion energy storage system explosion that killed two firemen in China earlier this year has proved inconclusive. A report by Beijing Fire Station noted that cell quality, battery management, electrical topology, external dust storms, and even wire arrangement could have led to the fire.

What was the cause of the explosion in Beijing?

An explosion occurred when Beijing firefighters were responding to a fire in a 25 MWh lithium-iron phosphate battery connected to a rooftop solar panel installation. Two firefighters were killed and one injured.

What happened at a lithium battery station in Beijing?

Source: Huaxia Energy The Apr 16 explosion of a lithium battery station in Beijing—resulting in at least two deaths—is the worst accident in China’s battery storage sector in recent years. [News report details of the accident] The cause of the explosion is still under investigation.

Did China's Investment hype cloud the development of battery storage?

Notably, the accident took place just two weeks after a fire broke out in an LG Chem battery unit in S. Korea. Safety is one of the chokepoints of the global development of battery storage. In China, the investment hype on electrochemical energy storage in recent years might have clouded the issue.

What is the thermal runaway gas explosion hazard in Beijing April 2021?

Beijing April 2021 BESS fire and explosion studied by CFD and simulation. Cable trench revealed as key mode of incident propagation through transferring hot gases. The thermal runaway gas concentration was determined based on the numerical results. The thermal runaway gas explosion hazard in BESS was systematically studied.

Will China's energy storage bloom be disturbed?

China’s energy storage bloom is unlikely to be disturbed in the long run, but the explosion in Apr. 16 brought clear short-term negative impacts on the nascent battery storage sector. Investment opportunities lie in safer energy storage technology or alternatives, especially those suitable to utility scale and long-form storage.
