Energy storage container fire extinguishing water fire

Are energy storage systems a fire risk?

Energy storage systems (ESS) are designed to store and release energy on demand. While they have many benefits, they can also pose a fire risk if not properly designed, installed, and maintained. Therefore, fire protection is an important consideration when it comes to energy storage systems.

What is a stationary energy storage system (ESS)?

Stationary Energy Storage Systems (ESS) are available in numerous designs. Beginning with small units for individual purposes with only small capacities, there are likewise large ESS parks with capacities up to several MWh (see Figure 1).

How can a high pressure Watermist prevent a battery fire?

The gas concentrations measured during the tests demonstrated that smoke extraction, for example by Explosion Prevention Openings (EPO), is essential to minimize the explosion risk. The high-pressure watermist system suppressed the battery fire successfully even with fully opened EPOs.
