Energy storage room fire extinguishing system

Does chemical suppression stop thermal runaway?

As concentration levels for a Class B fires are different than that of the Class C fires, chemical suppression alone will not stop thermal runaway. Suppression will extinguish a Class C fire inside the ESS container or building and will stop an electrolyte fire from off-gassing of the batteries but not thermal runaway.

Can a battery energy storage system control electrical fires?

However, these systems may be used in the computer or control rooms of an ESS to control any electrical fires. Thermal runaway in lithium batteries results in an uncontrollable rise in temperature and propagation of extreme fire hazards within a battery energy storage system (BESS).

Are energy storage systems flammable?

These systems combine high energy materials with highly flammable electrolytes. Consequently, one of the main threats for this type of energy storage facility is fire, which can have a significant impact on the viability of the installation.

Is fire suppression equipment included in an ESS?

suppression equipment may or may not be provided as an integral part of an ESS, or it may be optional. Depending on the case, the ESS shall comply with all applicable performance requirements in the standard with and/or without the fire detection and fire suppression equipment in place and operational.

Can a smoke extinguishing agent damage sensitive technical equipment?

The extinguishing agent used shall not damage the sensitive technical equipment Early detection can be provided by an Aspirating Smoke Detection (ASD system), which is able to detect the electrolyte gases generated by the excessive overheating of individual battery cells.

What is battery energy storage fire prevention & mitigation?

In 2019, EPRI began the Battery Energy Storage Fire Prevention and Mitigation – Phase I research project, convened a group of experts, and conducted a series of energy storage site surveys and industry workshops to identify critical research and development (R&D) needs regarding battery safety.
