Ensuring Safety in Grid-Scale Battery Systems | EP243

Clean Power Hour

In this episode of the Clean Power Hour, Tim Montague engages with industry leaders Dr. Zhehan Yi and Ryan Mayfield to discuss the critical topic of safety in grid-scale battery systems. As the demand for renewable energy surges, understanding the safety protocols and standards surrounding battery storage has never been more essential. The conversation delves into the rapid growth of battery installations across the United States, which have skyrocketed from approximately one gigawatt to nearly 17 gigawatts in just four years. With projections that BESS capacity could exceed 100 gigawatts in the US by the end of the decade, addressing safety concerns becomes paramount.

Dr. Yi emphasizes the importance of integrating safety measures early in the design process, particularly regarding thermal runaway risks associated with lithium-ion batteries, which dominate the market. He discusses how engaging with authorities having jurisdiction (AHJs) and adhering to fire codes can mitigate potential hazards and foster the successful adoption of these transformative technologies. The episode also covers fundamental safety standards and testing protocols, such as UL 9540 and UL 9540A, shedding light on how companies like CPS America are innovating to enhance reliability and safety.

Ryan Mayfield brings over 25 years of experience in solar PV and energy storage to the table, sharing insights from his work with developers and EPCs (engineering, procurement, and construction firms). He highlights the need for ongoing education within the industry to ensure all stakeholders—from facility owners to grid operators—are informed about the risks and best practices associated with battery systems.
