Samsung SDI Develops Special Fire Extinguishing System for ESS
Samsung SDI, the battery-making subdivision of South Korean tech giant Samsung Electronics, has built an extraordinary fire extinguishing system for facilities that store electricity generated by clean energy power plants as a solution to end a streak of fires that have destroyed more than 20 energy storage facilities since August 2017.
South Korea has some 1,500 energy storage system (ESS) facilities nationwide and 23 have been wrecked by fire and left inoperable. Based on Korea Electric Power Corp. (KEPCO), 30,232 megawatt-hours of electricity worth 6.5 billion won ( xxx) was lost. Samsung SDI said on Monday that the company has developed a special fire extinguishing system that would fundamentally stop fire from spreading even if there is a case of battery cell combustion inside an ESS.
New ESS facilities will be well equipped with the new system. The company planned to pay for safety upgrades for some 1,000 existing ESS facilities. The upgrade will cost up to 200 billion won.
The new fire deterrence system is comprised of high-tech chemicals applied with Samsung SDI's core technologies and materials that block heat from spreading. "When an ESS' interior catches fire and its temperature reaches a certain degree, special chemicals are automatically sprayed to extinguish the initial flame," Samsung SDI's senior managing director Heo Eun-ki was cited as saying.
Heo said that the new system would also prevent nearby cells from overheating. Other undamaged cells would cool off over a long period, sustaining its regular state. South Korean tech companies such as LG Chem has jumped into the speedily expanding ESS market. While LG Chem focuses on establishing a network of ESS grids using lithium-ion batteries, the Hyundai auto group combined with a state nuclear power company in September to use recycled electric car batteries in ESS facilities.
