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 is the scope of energy storage system standards?

The energy storage system standards cover both industrial large-scale energy storage systems and domestic energy storage systems. Appendix 1 provides a summary of applicable international standards for domestic battery energy storage systems (BESSs).

What are the international standards for battery energy storage systems?

Appendix 1 includes a summary of applicable international safety standards for domestic battery energy storage systems (BESSs). When a standard exists as a British standard (BS) based on a European (EN or HD) standard, the BS version is referenced. The standards are divided into the following categories: Safety standards for electrical installations.

Is energy storage a hazard?

Stored energy of any kind is a hazard. In the case of abnormal operation, damage, or swelling, immediately contact a qualified technician or the manufacturer. Residential energy storage systems (ESS) using lithium-ion batteries can present safety challenges for homeowners and firefighters.

Are domestic battery energy storage systems safe?

While few incidents involving domestic battery energy storage systems (BESSs) are known, questions have been raised regarding their safety. The concern stems from the large energy content within these systems.

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.
