OverviewSafetyHistoryTermsDesignApplicationsDeployments
Grid-scale battery standards and fire containment practices are at an early stage of development. Fire risks are one factor that has delayed the deployment of some utility energy storage systems. Most battery fires cannot be extinguished with water, which is the primary firefighting technique in most communities. A fire in a single cell can cascade to others via thermal runaway, possibly in milliseconds, potentially creating a major hazard.
