Do energy storage systems need a CSR?

Until existing model codes and standards are updated or new ones developed and then adopted, one seeking to deploy energy storage technologies or needing to verify an installation’s safety may be challenged in applying current CSRs to an energy storage system (ESS).

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.

What are the safety concerns with thermal energy storage?

The main safety concerns with thermal energy storage are all heat-related. Good thermal insulation is needed to reduce heat losses as well as to prevent burns and other heat-related injuries. Molten salt storage requires consideration of the toxicity of the materials and difficulty of handling corrosive fluids.

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.

What if energy storage system and component standards are not identified?

Energy Storage System and Component Standards 2. If relevant testing standards are not identified, it is possible they are under development by an SDO or by a third-party testing entity that plans to use them to conduct tests until a formal standard has been developed and approved by an SDO.
