IFSJ charts the battery suppression market, covering BESS protection, EV pack materials, and logistics controls, with fresh data, regulatory updates and regional trends
In response to rising battery incidents across energy storage, transport and waste streams, demand for lithium-ion fire suppression and passive containment has accelerated.
This report reviews the global market serving battery energy storage systems, electric vehicles and micromobility and high-risk logistics, summarising current market value and growth, strengths and constraints in active and passive protection, recent standards and policy changes and provides regional insights for buyers and specifiers.
Market overview
Vendors serving lithium-ion battery energy storage now participate in a multibillion-dollar protection market.
According to Verified Market Reports, fire protection for battery energy storage systems was valued at 4.2 billion dollars in 2024 and is projected to reach 12.8 billion dollars by 2033, a 13.5 percent CAGR.
Within that, dedicated suppression for lithium-ion BESS was estimated at 1.2 billion dollars in 2024, with growth to 3.8 billion dollars by 2033 at 15.5 percent CAGR.
Passive protection in vehicles is a second growth engine.
IDTechEx expects fire protection materials used inside EV packs to grow at about 15 percent CAGR through the next decade, driven by pack-level propagation barriers such as mica sheets, ceramics, aerogels and intumescent layers.
Strengths
Two factors support adoption.
First, standards and test methods are maturing.
UL Solutions published the fifth edition of UL 9540A in March–April 2025, adding clearer criteria on cell-to-cell propagation, high-temperature chemistries and protocols for rooftop and open-garage BESS installations, which improves comparability of system-level results for buyers.
Second, field guidance increasingly aligns on practical tactics.
NFPA states that water is a suitable extinguishing medium for lithium-ion systems, countering confusion with metallic lithium, while U.S.
guidance such as the Washington State Patrol’s January 2025 EV fire study reinforces suppression and post-stabilisation practices that equipment suppliers can design around.
On the passive side, OEM interest in cell-to-pack architectures is expanding use of thin, lightweight propagation barriers, supporting steady material demand, according to IDTechEx.
Challenges
Market growth faces three practical hurdles.
Effectiveness varies by scenario: condensed aerosols, water mist, water deluge and encapsulating additives show different performance against flame knockdown versus heat removal and re-ignition risk; federal and state guidance still describes cases where “let it burn” with controlled cooling remains the safest option, which complicates one-size procurement.
Codes are moving targets.
NFPA 855 is progressing toward its 2026 edition, with working materials in 2025 indicating changes to maximum energy tables and linkages to UL 9540A interpretations, so designs specified today may require near-term revisions.
Finally, incident data from micromobility continues to pressure residential and light-commercial risk management: UK regulators recorded 211 e-bike and e-scooter fires in 2024, which sustains public-safety scrutiny and drives demands for certified systems and storage.
Recent developments
Standards and policy shifts in the last nine months will shape purchasing decisions.
UL Solutions updated UL 9540A in March–April 2025 and testing houses began rolling out programs aligned to the new edition; trade press summarised added protocols for emerging chemistries and installations.
In the United States, the clean-power sector signaled wider adoption of the next NFPA 855 edition via a national safety blueprint, while state policy moved in parallel: California’s SB 283 would require CEC-authorised or locally permitted ESS to meet new fire safety standards and inspection requirements.
Transport rules also tightened.
IATA’s 2025 lithium and sodium-ion battery guidance updated packing instructions and documentation pathways that affect air shipments of cells, packs and recalled units, influencing suppression and containment needs in logistics and waste handling.
Regional Insights
North America
Procurement is anchored on UL 9540A testing and NFPA 855 adoption, with agencies referencing large-flow water tactics and post-event stabilisation for EV incidents; California’s SB 283 points to closer alignment between permitting and fire-safety inspections for ESS.
Europe
Consumer-product risk remains visible.
UK OPSS logged 211 e-bike and e-scooter fires in 2024, sustaining emphasis on certified charging and storage solutions; e-bike electrical system standards such as EN 15194 continue to guide compliance messaging.
Asia-Pacific
China announced stricter EV battery safety rules to cut fire and explosion risk from July 2026, mandating tougher tests for thermal runaway resilience and fast-charge tolerance; this will ripple into supply chains serving export vehicles and components.
Middle East & Africa and Latin America
Growth in grid-connected storage and transport logistics is bringing more projects under UL 9540A-style test evidence and IATA’s 2025 transport guidance, shaping specifications for suppression, containment and incident packaging in warehouses and hubs.
