In order to improve the safety of energy storage, on May 3, 2022, South Korea raised the safety standards of energy storage systems to prevent the Korean energy storage systems from catching fire. The measures focus on strengthening battery safety standards, improving manufacturing processes, making up for deficiencies in battery installation and operation management, and ensuring the reliability of fire accident investigation results and measures to ensure implementation capabilities. These include installing fire baffles in units of 5MWh or less when installing batteries, establishing real-time safety management systems at all energy storage system locations, and more. It is reported that since June last year, the Korean Ministry of Industry, Trade and Resources has investigated 4 ESS fire accidents, and based on the findings, listened to the opinions of experts and the industry, and proposed measures to strengthen the safety of energy storage systems.

• Strengthen battery safety standards and improve manufacturing processes
• Make up for the deficiencies in battery installation and operation management
• Increase safety standards according to the appearance of various ESS such as batteries after use
• Measures to ensure the reliability of fire accident investigation results and the ability to implement
• Use digital technologies to expand security management infrastructure

As early as February 7, the South Korean Ministry of Fire Protection issued the "Fire Response Guidelines for Energy Storage Systems". The document pointed out that the main reason for the fire and explosion of the energy storage system was the combustible gas generated by the battery, and to prevent the generation of combustible gas when the energy storage system caught fire. The best way to do this is to cool the battery, and this Response Guide provides recommendations for different fire levels.
