How does ESS design affect fire and explosion safety?

Several competing design objectives for ESS can detrimentally affect fire and explosion safety, including the hot aisle/cold aisle layout for cooling efficiency, protection against water and dust ingress into the enclosure, and the use of larger cells with increased energy density.

What are energy storage systems (ESS)?

Energy storage systems (ESS) are being installed in the United States and all over the world at an accelerating rate, and the majority of these installations use lithium-ion-based battery technology.

Can passive protection be used as a sole explosion protection scheme?

The two main challenges in using passive protection methodology are design constraints for the enclosure and lack of validation data to support calculation methodology. These challenges make it difficult to obtain a feasible design for deflagration venting of ESS enclosures as the sole explosion protection scheme for most configurations.

What are the different types of explosion control options for ESS?

The two types of explosion control options for ESS, NFPA 68 deflagration venting and NFPA 69 exhaust ventilation, are based on a design basis determined from UL 9540A test data. This testing is meant to provide baseline data for the analysis and is generally extrapolated to a sufficiently conservative hazard scenario for the ESS installation.

Why are explosion hazards a concern for ESS batteries?

For grid-scale and residential applications of ESS, explosion hazards are a significant concern due to the propensity of lithium-ion batteries to undergo thermal runaway, which causes a release of flammable gases composed of hydrogen, hydrocarbons (e.g. methane, ethylene, etc.), carbon monoxide, and carbon dioxide.
