The RP focuses on three main aspects of grid-connected energy storage: safety, operation and performance. These aspects are assessed for electricity storage systems in general, i.e. a technology agnostic approach). Furthermore, recommendations applying only to specific energy storage technologies are provided wherever necessary.
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.
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.
Ultimately, energy storage safety is ensured through engineering quality and application of safety practices to the entire energy storage system. Design and planning to prevent emergencies, and to improve any necessary response, is crucial.
Another method of developing hybrid storage systems is to combine batteries with different chemistries. Such hybrid systems are particularly promising for long duration energy storage in grid applications. Pb-acid batteries are extensively used for their low capital cost and wide availability.
Designing resilient systems: although it is impossible to design for any scenario, energy storage systems should be designed to withstand common and uncommon environmental hazards in the areas they will be deployed.
