Advances in Fire Suppression Technologies
-
Stat-X Condensed Aerosol Systems:
- Effectiveness: Stat-X has been proven effective in extinguishing single- and double-cell lithium-ion battery fires through extensive testing by organizations like DNV and PVEL in compliance with UL 9540A.
- Features: These systems offer total flooding, limit thermal runaway, and integrate well with detection methods. They are environmentally friendly, requiring minimal cleanup and no piping infrastructure.
-
Immersion Cooling Technology:
- Operation: This technology involves submerging battery cells in a non-flammable, dielectric liquid that directly absorbs heat, preventing thermal runaway.
- Advantages: It provides proactive thermal management, prevents fire propagation by isolating cells from oxygen, and offers real-time monitoring through integrated battery management systems.
-
Advanced Detection and Suppression Integration:
- Gas Detection: Early detection through gas sensors allows for rapid intervention by shutting down power to affected cells or activating suppression systems before fires occur.
- Layered Protection: Combining detection with suppression technologies like Stat-X ensures comprehensive safety, especially in lithium-ion BESS where traditional methods are often ineffective.
-
Regulatory Standards and Compliance:
- UL 9540 and NFPA 855: These standards dictate the safety and performance requirements for energy storage systems, including fire suppression. Compliance with these standards ensures that systems undergo rigorous testing to prevent fire propagation.
These advancements highlight a shift towards proactive and integrated fire safety solutions that address the unique challenges of BESS, focusing on preventing thermal runaway and ensuring effective containment and suppression when incidents occur.
