6 Frequently Asked Questions about “The latest safety regulations for mobile energy storage power supplies”

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 does ul 9540 mean for energy storage systems & equipment?

The third edition of the UL 9540 Standard for Safety for Energy Storage Systems and Equipment, published in April 2023, introduces replacements, revisions and additions to the requirements for system deployment.

Can energy storage be used in New applications?

Risks of energy storage in new applications: Codes, standards, and testing protocols for energy storage systems tend to focus on grid-scale deployments. However, energy storage is increasingly being used in new applications such as support for EV charging stations and home back-up systems.

What is mobile energy storage system?

The primary application of mobile energy storage systems is for replacement of polluting and noisy emergency diesel generators that are widely used in various utilities, mining, and construction industry. Mobile ESS can reduce use of diesel generators and provide a cleaner and sustainable alternative for reduction of GHG emissions.

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.

Are there safety gaps in energy storage?

Table 6. 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.
