SHENZHEN, China, June 25, 2025 /PRNewswire/ -- CLOU Aqua C2.5 5MWh liquid-cooled energy storage system has successfully completed an extraordinary 59-hour and 10-minute Large-Scale Fire Test - setting a new benchmark for energy storage safety evaluation. The test was fully witnessed and documented by CSA Group personnel throughout the entire process. The system demonstrated exceptional resilience by maintaining complete structural integrity while withstanding temperatures exceeding 1,300°C, without resulting thermal runaway propagation between initiating BESS and target BESSs nearby.

The Large-Scale Fire Test is designed to evaluate the possibility of fire spreading from one system enclosure to adjacent systems in centralized installations of energy storage systems. During the test, under conditions where the triggered system was fully engulfed in flames, the fire did not cause any adjacent systems to exhibit valve opening or thermal runaway signs. This demonstrates the product's exceptional flame-retardant and thermal insulation performance, meeting the customized testing requirements of the client.
This testing milestone embodies Clou's profound commitment to addressing clients' safety imperatives. By ignition of Container A, sustained combustion persisted for 59 hours and 10 minutes until complete extinguishment without reignition. The testing methodology accurately simulates the full progression of extreme fire scenarios - from ignition, escalation to natural attenuation. The obtained critical data provides essential parameters for optimizing fire protection system design in energy storage plants.
"The test results have far exceeded our most stringent safety benchmarks. CLOU's integrated approach combining superior flame retardancy, advanced thermal management and inherent system protection represents a significant advancement in energy storage safety engineering." Eric Wang, System Director of CLOU ESS Division emphasized the solution's forward-looking design, specifically engineered to address emerging challenges posed by high-energy-density battery technologies.
The successful evaluation from this test conclusively demonstrates Aqua C2.5's readiness for GW-scale deployment. The system delivers unparalleled protection against prolonged thermal runaway events while establishing new certification benchmarks for the global energy storage industry. This milestone reinforces CLOU's leadership in next-generation energy storage safety technologies, carrying significant implications for utility-scale, commercial and industrial applications worldwide. The system's performance sets a new safety standard benchmark for the sector, demonstrating that extreme safety protocols and high operational efficiency can be seamlessly integrated into modern energy storage solutions.

CLOU Aqua C2.5 Establishes Unprecedented Safety Benchmark with 59-Hour Large-Scale Fire Test
TBILISI, Georgia, Dec. 25, 2025 /PRNewswire/ -- On December 25th, Beijing time, Georgian Railway Modernization Project constructed by China Railway 23rd Bureau Group Co., Ltd., is officially put into operation. After 13 years of hard work, this major achievement of China-Georgia cooperation under the Belt and Road Initiative has injected strong impetus into the transportation upgrade and economic development of Georgia, and also demonstrated the outstanding capabilities of Chinese infrastructure enterprises in the overseas railway market.
The railway is located in central Georgia, starting from the city of Zestaponi and ending in the city of Khashuri, with a total length of 43.911 kilometers. It serves as the "main artery" for transportation between the east and west of the country. The project involves the upgrading and renovation of existing lines as well as the construction of new ones, covering multiple fields such as line design, civil engineering construction, power supply, communication systems, and station facilities. The construction was particularly challenging due to the complex geological conditions, with key tasks such as tunnel excavation, high slope embankment protection, and bridge beam installation all faced with significant obstacles. The construction team of China Railway 23rd Bureau Group Co., Ltd. adopted a "lean and efficient" management model, flexibly adjusted the construction plans, deepened cooperation with local enterprises, and relied on technological innovation to overcome a series of technical difficulties. They strictly adhered to safety standards throughout the process to ensure the smooth progress of the project.
During the construction period, the project management actively fulfilled its social responsibilities, providing employment for approximately 1,000 local workers. This not only has helped local people increase their income but also enabled them to acquire professional skills through technical training, which allows them to participate in and witness the development and changes of their hometowns.
This project is the largest railway project newly built and successfully put into operation in Georgia. As an important part of the "Trans-Caspian International Transport Corridor", the official operation of the project is of great significance for enhancing the overall transportation capacity of Georgian railways, promoting logistics transportation between China and Europe, and driving regional economic development. The average travel efficiency from Tbilisi, the capital of Georgia, to the western Black Sea port thus will increase by 37%, and the annual freight capacity will double. This will not only promote the industrial upgrading of Georgia and the development of the regions along the line but also strengthen the trade connection and cooperation with neighboring countries.
