By successfully completing an impressive 59-hour and 10-minute Large-Scale Fire Test, the CLOU Aqua C2.5 5MWh liquid-cooled energy storage system has raised the bar for energy storage safety assessment. Employees of the CSA Group saw and recorded the test in its entirety. The system showed remarkable resilience by retaining all of its structural integrity at temperatures above 1,300°C without experiencing thermal runaway propagation between the adjacent initiating BESS and target BESSs.
