FAQS about Safety issues faced by the development of new energy storage

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 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.

Can energy storage systems be scaled up?

The energy storage system can be scaled up by adding more flywheels. Flywheels are not generally attractive for large-scale grid support services that require many kWh or MWh of energy storage because of the cost, safety, and space requirements. The most prominent safety issue in flywheels is failure of the rotor while it is rotating.

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 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.

Can energy storage be used as a temporary source of power?

However, energy storage is increasingly being used in new applications such as support for EV charging stations and home back-up systems. Additionally, many jurisdictions are seeing increasing use of EVs and mobile energy storage systems which are moved around to be used as a temporary source of power.
