What's new in energy storage safety?

Since the publication of the first Energy Storage Safety Strategic Plan in 2014, there have been introductions of new technologies, new use cases, and new codes, standards, regulations, and testing methods. Additionally, failures in deployed energy storage systems (ESS) have led to new emergency response best practices.

Are energy storage systems safe?

Altogether, like other electric grid infrastructure, energy storage systems are highly regulated and there are established safety designs, features, and practices proven to eliminate risks to operators, firefighters, and the broader community.

Can a large-scale solar battery energy storage system improve accident prevention and mitigation?

This work describes an improved risk assessment approach for analyzing safety designs in the battery energy storage system incorporated in large-scale solar to improve accident prevention and mitigation, via incorporating probabilistic event tree and systems theoretic analysis. The causal factors and mitigation measures are presented.

Are battery energy storage facilities safe?

FACTS: No deaths have resulted from energy storage facilities in the United States. Battery energy storage facilities are very different from consumer electronics, with secure, highly regulated electric infrastructure that use robust codes and standards to guide and maintain safety.

What happens if an energy storage system fails?

Any failure of an energy storage system poses the potential for significant financial loss. At the utility scale, ESSs are most often multi-megawatt-sized systems that consist of thousands or millions of individual Li-ion battery cells.

What are energy storage safety gaps?

Energy storage safety gaps identified in 2014 and 2023. Several gap areas were identified for validated safety and reliability, with an emphasis on Li-ion system design and operation but a recognition that significant research is needed to identify the risks of emerging technologies.
