In a recent commentary, Joe DeBellis, Global Head of Clean Energy at Firetrace International, outlined a strategy for addressing fire safety concerns in Battery Energy Storage Systems (BESS) projects. The discussion aims to correct common industry myths and improve public support for the rapidly growing energy technology.

A nationwide survey conducted by Firetrace revealed that while 71% of Americans support BESS, opposition is often driven by fears over fire safety. The survey also found that 66% of people would be more likely to support a local BESS project if advanced fire suppression systems were installed.

DeBellis addressed two prevalent myths:

1. Myth: Thermal runaway is the only primary fire risk. While thermal runaway is a major hazard, DeBellis pointed to an EPRI report showing that approximately 43% of BESS site fires originate in electrical equipment, such as the Power Conversion System (PCS). He advocated for a strategy that includes targeted clean agent suppression for electrical components to stop fires at common ignition points.

2. Myth: Clean agents are meant to stop thermal runaway. DeBellis clarified that clean agents are most effective for protecting sensitive electrical equipment, not for suppressing battery cell failures directly. For the battery enclosures, Firetrace partners with FirePro to use a total-flood condensed aerosol solution specifically designed to control fires associated with lithium-ion hazards.

By combining focused clean agent systems for electrical gear with total-flood aerosol suppression for battery enclosures, the company's approach aims to protect the entire BESS site from multiple ignition sources.
