To effectively mitigate the fire and explosion risks associated with BESS, it is essential to begin by understanding the types of batteries typically utilised in these systems, as well as the potential causes of fires and explosions. Several battery technologies are employed in BESS, each with its own unique characteristics and advantages.
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.
This arrangement makes it difficult to use a standard exhaust ventilation methodology to design an explosion prevention system. An innovative approach is used to purge the battery gas from individual Powin Stacks™ and from the main enclosure during a thermal runaway event.
A CFD study was performed for the Powin 53-ft ESS enclosure to assess the capability of the explosion prevention system to maintain the global battery gas volume fraction lower than 25% of its LFL.
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.
Unfortunately, a small but significant fraction of these systems has experienced field failures resulting in both fires and explosions. A comprehensive review of these issues has been published in the EPRI Battery Storage Fire Safety Roadmap (report 3002022540 ), highlighting the need for specific eforts around explosion hazard mitigation.
Utilities are uniquely positioned to impact energy storage safety practices, especially in the absence of clear risk mitigation guidelines. Effective solutions will require additional data to characterize technologies, integration practices, failure incidents and their impacts, as well as controlled testing and modeling to frame future solutions.
