Since the beginning of 2017, there have been 7 fire accidents in South Korea's energy storage projects, affecting the capacity of 78MWh. In December 2017, the Engie Group's energy storage demonstration project in Drogenbos, Belgium also occurred. Fire accident. In the lithium-ion battery energy storage project put into operation in South Korea in 2017 and the first half of 2018, the project capacity affected by the fire accident accounted for 3%. Although this figure is slightly more, the government or the fire department also It should not be overreacted, but should continue to develop and improve relevant standards and norms.
The energy storage system is designed to release the stored energy in an orderly manner. When the internal error occurs in the system, the stored energy is quickly released in an uncontrolled state, causing the device to heat up rapidly, which may lead to fire, or even cause Explosion. In order to prevent the battery from damaging the entire energy storage system, Korea began to use active equalization technology and passive equalization technology to manage the entire system.
Considering the nature of the fire incident in the energy storage project, it takes some time to find the cause of the fire. The participating companies of the project involved in the fire accident and the Ministry of Trade, Industry and Energy (MOTIE) continue to conduct a large number of investigations.
South Korea's recent energy storage project fire accident has a greater impact on nickel-manganese-cobalt ternary batteries (NMC), which may lead to a significant increase in demand for lithium iron phosphate (LFP) batteries. Despite the lower energy density of lithium iron phosphate batteries , but it has a high stability, so it is not easy to catch fire.
To be cautious, the South Korean government has carried out safety inspections on 58 large-scale energy storage power plants of 10 MWh or more, and plans to test 1008 energy storage systems registered in the country. In addition, the Ministry of Trade, Industry and Energy of Korea is also taking measures to strictly regulate the standard battery with the project approval process.
In order to minimize the possibility and adverse effects of the fire incident, we should carefully analyze the results of the investigation into the fire accidents in South Korea and other regions. From the survey results, some of the incidents only involve a certain technology or Company, and other events may prompt us to modify the entire industry standard and implementation specifications.
