How do I design an explosion prevention system for an ESS?

The critical challenge in designing an explosion prevention system for a ESS is to quantify the source term that can describe the release of battery gas during a thermal runaway event.

Does immersion cooling reduce fire risk?

High-profile incidents, such as the fire at the Moss Landing Energy Storage Facility, have underscored the limitations of current cooling and safety measures. Immersion cooling, patented for BESS by EticaAG (a joint venture between Etica Battery and AGI), offers optimal thermal management and advanced fire suppression.

What happens if the explosion prevention system is activated?

These values drop to approximately 2 g after the explosion prevention system has been activated. The global concentration of the battery gas inside the failing half stack cabinet is above the 25% LFL limit for less than 1 min before the explosion prevention system is activated for both failure scenarios.

Can a flammable battery gas source be used for explosion control?

NFPA 855 recommends that a UL 9540A ( ANSI/CAN/UL, 2019) test be used to evaluate the fire characteristics of an ESS undergoing thermal runaway for explosion control safety systems. An approach to determine a flammable battery gas source term to design explosion control systems has been developed based on UL 9540A or similar test data.

Why do energy storage systems have a safety hazard?

As the reactions progress, they generate heat, which increases the chemical activity, creating a self-sustaining feedback loop that can culminate in fire or explosion. The process poses a significant safety hazard and undermines the reliability and operational efficiency of energy storage systems.

How does immersion cooling improve Bess safety?

Traditional fire suppression methods typically offer incremental improvements, primarily addressing fires after they ignite. In contrast, immersion cooling fundamentally redefines BESS safety by proactively eliminating ignition conditions altogether.
