Whether to set up dry sand fire extinguishing in energy storage power station

What are the standards for ESS fire suppression systems?

Two commonly referenced standards for ESS fire suppression systems are FM Global Data Sheet (FM DS) 5-33 and NFPA 855. In the event of thermal runaway, it is essential to rapidly cool the affected module and its surroundings to prevent a chain reaction of battery fires.

What is the NFPA 855 standard for stationary energy storage systems?

Setting up minimum separation from walls, openings, and other structural elements. The National Fire Protection Association NFPA 855 Standard for the Installation of Stationary Energy Storage Systems provides the minimum requirements for mitigating hazards associated with ESS of diferent battery types.

Does NFPA 855 permit alternative fire suppression systems?

NFPA 855 also permits the use of alternative fire suppression systems if they successfully pass large-scale fire testing in accordance with Underwriters Laboratories (UL) 9540A, “Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems,” or an equivalent standard.

Why should you use ESS power control?

Optimized power control allow significant reductions, e.g., in fuel and maintenance costs and emissions. In all applications, land or marine, ESS can provide the flexibility and freedom to store electrical energy and utilize the energy when it is most beneficial for system operation.

How do ESS fire agents work?

These agents are common in the protection of sensitive electronics and act by either cooling or displacing oxygen. Challenges in the suppression of ESS fires include limited effectiveness due to the extreme heat generated during the thermal runaway process, as well as the duration of the incident.

How do you extinguish eficiency in an ESS?

Given the thousands of cells in an ESS, this is not possible in practice. The next best option related to extinguishing eficiency is to inject the extinguishing agent into each module housing several cells and, in fact, such systems are commercially available.
