I. Clarify Export Markets and Certification Systems First
There is no single, globally unified certificate for exporting energy storage fire protection systems (covering fire detection, gas detection, fire suppression, and alarm linkage); instead, certifications are obtained based on the specific target market. The North American market relies on NFPA 855 (*Standard for the Installation of Stationary Energy Storage Systems*) as the design basis and UL 9540A (*Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems*) as the primary testing standard.
The European market is based on the CE mark, supplemented by EN series product standards and certifications from bodies such as Germany’s VdS. Markets in the Middle East, Southeast Asia, and Australia/New Zealand often adopt North American or European standards, with the scope of certification determined by project owner requirements.
Exporting enterprises should first identify the necessary set of qualifications based on “target market + customer project type” before planning their certification investment, thereby avoiding the inefficiency of pursuing a full suite of certifications unnecessarily.

North America: The Dual-Track Approach of NFPA 855 and UL 9540A
North America is the market with the strictest requirements for energy storage fire protection.
Since its initial release in 2019 and a major revision in 2023, NFPA 855 has been further strengthened in its 2026 edition: all lithium-ion battery energy storage systems (BESS) must undergo large-scale fire testing and complete an explosion hazard analysis in accordance with NFPA 68 (pressure relief design) and NFPA 69 (explosion protection, such as Combustible Concentration Reduction Systems or CCRS).
Regarding test execution, UL 9540A is currently the only national standard for fire safety testing of battery energy storage systems explicitly cited by NFPA 855 in North America. It evaluates thermal runaway fire propagation behavior across levels ranging from individual cells and modules to complete cabinets; the resulting test data is a prerequisite for fire department approval of project construction. System-level safety certification operates within the framework of UL 9540 (“Standard for Energy Storage Systems and Equipment”) and incorporates component standards such as UL 1973 (stationary batteries) and UL 1741 (inverters).
Gas detection components must be certified under UL 2075; revisions made in 2026 introduced new requirements for detecting hydrogen, carbon monoxide, and lithium-ion electrolyte vapors, making specialized detectors capable of sensing gas emissions at ppm or even ppb levels a standard feature for North American projects.
III.
Europe: CE Marking, EN Standards, and VdS Certification
Energy storage fire protection systems in the European market must comply with the CE marking framework (Low Voltage Directive LVD and Electromagnetic Compatibility Directive EMC) and carry a Declaration of Conformity. Additionally, they must meet EN standards based on the specific application scenario: battery energy storage system safety involves standards such as EN 50604-1, while clean-agent fire suppression systems are designed and installed according to the EN 15004 series.
VdS (a German fire protection certification body) issues one of Europe’s most influential certifications for fire protection products, including specific certifications for lithium-ion battery off-gas detection and thermal runaway suppression systems (e.g., VdS S 619002). Some North American projects also recognize VdS certification under the “equivalency” clause (Section 1.5) of NFPA 72, enabling cross-market acceptance.
Project owners and insurance companies in Europe generally require systems to hold VdS or equivalent third-party certification; for exporting companies targeting high-end markets like Germany and the Nordic region, obtaining VdS certification is virtually a standard requirement.
IV. Component-Level Certification for Fire Suppression Systems
Fire suppression media and components used in energy storage fire protection systems are subject to specific certifications. Fire suppression units—such as those utilizing heptafluoropropane (FM-200), perfluorohexanone (Novec 1230), or nitrogen inerting—must be tested against relevant international standards (e.g., ISO 14520/EN 15004 or NFPA 2001 for gas-based systems). Water mist and aerosol systems obtain certification under standards such as UL 2167, while detection and control components (such as point-type detectors, aspirating smoke detectors, and control modules) are certified to UL/ULC and FM standards (e.g., FM 6540 for off-gas detection). There is an industry consensus that traditional clean-agent fire suppressants and conventional water sprinkler systems have limited effectiveness in suppressing the propagation of thermal runaway between lithium-ion battery cells;
issues include sustained high surface temperatures and the decomposition or failure of the extinguishing agents. Consequently, an increasing number of systems are adopting a combined approach involving nitrogen inerting (reducing oxygen concentration below the combustion threshold) and early off-gas detection. Certification for these new technologies (e.g., UL 2075, FM, VdS) is becoming a key differentiator for export competitiveness.
V. Implementation Roadmap and Trends
A three-step approach is recommended for the practical implementation of export-oriented energy storage fire protection systems: First, conduct a standards gap analysis by translating the requirements of target markets, project types, owners, and insurance companies into a certification checklist—focusing on NFPA 855 and UL 9540A/9540 for North America, and CE, EN, and VdS for Europe. Second, pursue tiered component certification; detectors, controllers, and fire suppression units can be submitted individually to third-party laboratories (such as UL Solutions, VdS, or FM) for testing, securing certifications for core components before proceeding to full system integration. Third, establish a compliance maintenance mechanism;
certifications from bodies like UL and FM typically entail ongoing factory inspections (e.g., UL’s multiple annual audits), requiring manufacturers to maintain production consistency and monitor annual revisions to standards like NFPA 855. Regarding trends, the 2026 edition of NFPA 855 elevates large-scale fire testing from a “project-specific requirement” to a “general threshold,” makes off-gas detection mandatory rather than optional, and designates explosion protection analysis as a required document for approval—shifting the export threshold for energy storage fire protection systems from merely “having certification” to “possessing a complete chain of evidence regarding fire and explosion safety.”
Conclusion
Export qualifications for energy storage fire protection systems can be summarized as follows: market-based tiering;
adherence to NFPA/UL standards for North America and CE/EN/VdS for Europe; specialized component certification; and a complete chain of evidence. Success in supplying fire protection systems to global energy storage projects requires locking in the appropriate standards for target markets, securing core component certifications prior to system integration, and proactively addressing the new requirements for large-scale fire testing and explosion analysis introduced by the 2026 edition of NFPA 855.
