Active Fire Protection Systems for Battery Energy Storage Installations (BESS)

LIFEGUARD HMS® Technology Automatic Fire Detection & Suppression System for Battery Energy Storage Systems

Protecting the World's Transition to Clean Energy

The future of energy is increasingly powered by Battery Energy Storage Systems (BESS). From utility-scale renewable energy projects and smart grids to data centres, industrial facilities, electric vehicle charging infrastructure, and commercial microgrids, lithium-ion battery technology has become the foundation of modern energy resilience.

As battery installations continue to increase in capacity and complexity, so does the importance of effective fire protection. Battery-related incidents present unique challenges due to high energy density, elevated temperatures, combustible gas release, and the possibility of thermal runaway within battery cells.

Traditional fire protection strategies alone may not adequately address these evolving hazards. Modern Battery Energy Storage Systems require integrated fire safety solutions that combine early detection, intelligent monitoring, automatic suppression, and emergency response planning.

To meet these challenges, LIFEGUARD has developed an advanced Active Fire Protection System for Battery Energy Storage Installations utilizing HMS® (Hydrated Mica Suspension)—a mineral-based fire suppression technology engineered specifically for lithium-ion battery applications.

Comprehensive Fire Protection for Battery Energy Storage Systems

Fire safety in Battery Energy Storage Systems should be viewed as a layered strategy rather than a single product. Effective protection begins with hazard identification and extends through early detection, automatic suppression, emergency notification, system isolation, and post-incident management.

The LIFEGUARD HMS® Technology Automatic Fire Suppression System is designed to form part of this integrated approach by protecting battery enclosures, battery containers, battery cabinets, and energy storage installations against developing fire incidents.

Understanding Lithium-Ion Battery Fire Hazards

Lithium-ion batteries differ fundamentally from conventional fire risks.

A battery incident may involve:

• Internal cell failure
• Electrical short circuits
• Mechanical damage
• Overcharging
• Manufacturing defects
• External heating
• Battery Management System abnormalities
• Thermal runaway propagation
• Release of combustible gases
• Elevated compartment temperatures

Once thermal runaway develops within one battery cell, adjacent cells may also be affected depending on battery chemistry, module design, spacing, and enclosure configuration.

This is why dedicated Battery Energy Storage Fire Protection Systems are becoming an essential element of modern energy infrastructure.

HMS® Technology – Developed for Lithium-Ion Battery Fire Applications

HMS® (Hydrated Mica Suspension) is LIFEGUARD's proprietary mineral-based extinguishing medium developed for products and systems intended for lithium-ion battery fire protection.

The formulation consists of specially processed hydrated mica dispersed in a water-based suspension.

When discharged through an engineered suppression system, HMS® is intended to:

• Support cooling of affected battery areas
• Provide mineral-based surface coverage
• Assist in controlling visible fire development within protected compartments
• Complement engineered battery fire protection strategies

Because battery incidents vary according to battery chemistry, enclosure design, state of charge, and operating conditions, system performance should always be evaluated as part of an engineered fire protection solution.

Automatic Fire Detection & Suppression

The LIFEGUARD BESS Fire Protection System combines intelligent fire detection with automatic suppression technology.

A typical system may include:

• Smoke Detection
• Heat Detection
• Gas Detection (application dependent)
• Fire Alarm Control Panel
• Suppression Control Panel
• HMS® Agent Storage Cylinders or Tanks
• Stainless Steel Distribution Piping
• Precision Engineered Discharge Nozzles
• Automatic Release Valves
• Manual Emergency Release
• Audible & Visual Alarm Systems
• Remote Monitoring Interface
• Battery Management System (BMS) Interface (where specified)

Upon activation by the detection system, HMS® is automatically discharged into the protected enclosure to support fire suppression and cooling within the designated hazard zone.

Intelligent Fire Detection

Early detection is fundamental to effective battery fire protection.

The LIFEGUARD system can be configured with application-specific detection technologies that continuously monitor protected spaces for indicators such as elevated temperature, smoke, or other fire-related conditions.

Upon detection of predefined alarm criteria, the system may:

• Activate automatic suppression
• Generate local alarms
• Notify remote monitoring systems
• Interface with Battery Management Systems (where configured)
• Support emergency shutdown procedures
• Assist emergency response coordination

HMS® Automatic Suppression

Following system activation, HMS® is discharged through a network of precision-designed nozzles to distribute the extinguishing agent throughout the protected compartment.

The engineered discharge pattern is intended to:

• Reach designated battery protection zones
• Support cooling of affected areas
• Provide mineral-based surface coverage
• Assist suppression of visible flames within the enclosure
• Complement overall battery fire management strategies

System design, nozzle placement, and agent quantity are determined through project-specific engineering.
