This YouTube Podcast is a comprehensive overview of battery energy storage systems (BESS) for risk engineers. The Podcast discusses what BESS are, their importance in balancing the grid and providing backup power, their components (including batteries, battery management systems, and power conversion systems), and their applications in residential, commercial, and industrial settings. Additionally, the speaker explores the risks associated with BESS, particularly thermal runaway and cascading effects, and highlights the importance of fire protection systems and emergency response procedures. Finally, the video provides examples of successful BESS installations and emphasizes the ongoing need for research and development in this rapidly evolving field.
