CLOU Enhances Fire Safety Systems through New Insights

CLOU Releases Comprehensive Fire Safety White Paper

CLOU, a prominent provider of energy storage systems, has unveiled its newly released white paper focusing on Active Ventilation & Explosion-Proof Systems. This significant document provides a thorough examination of the company’s advanced fire safety architecture tailored for energy storage systems. The release arrives on the heels of a notable achievement—the successful conduct of a 59-hour and 10-minute Large-Scale Fire Test, showcasing the capabilities of their 5MWh Aqua C2.5 liquid-cooled Battery Energy Storage System (BESS).

Insights from the Large-Scale Fire Test

The Large-Scale Fire Test set up by CLOU was skillfully witnessed and documented by the CSA Group. This rigorous test was designed to replicate an extreme thermal runaway scenario that could potentially occur within energy storage systems. By arranging four fully loaded Aqua C2.5 containers into a compact 20MWh system, CLOU effectively mimicked actual high-density layouts typical in energy deployments. Container A was deliberately ignited, sustaining combustion for an impressive duration of nearly 60 hours, with internal temperatures that soared beyond 1300°C. Notably, the test was conducted without activating any fire suppression systems, thus allowing for a true evaluation of the fire endurance and safety performance of CLOU’s innovative system.

Addressing Industry Safety Concerns

In light of increasing safety concerns associated with energy storage systems, including numerous fire and explosion incidents reported around the world, CLOU has been proactive. The North American region, recognized for its stringent energy storage safety standards, has implemented a robust regulatory framework focused on lifecycle risk management. This covers everything from individual cell protection to comprehensive station-wide systems. Key standards such as NFPA 855, NFPA 68, NFPA 69, UL 9540, and CSA/ANSI C800 guide the industry in maintaining safety and reliability.

CLOU’s Comprehensive Fire Protection Approach

In alignment with these regulations, CLOU has meticulously developed a detailed multi-layered fire protection system designed to safeguard customer assets throughout their operational lifecycle. The safety protocols outlined in the white paper hinge on lean engineering principles and consist of multiple key components:

Components of the Fire Protection System

Early Warning & Detection of Thermal Runaway – The Battery Management System (BMS) continuously monitors voltage and temperature, promptly triggering alarms and disconnecting circuits to mitigate risks of propagation. This system activates vital ventilation and explosion-proof mechanisms to neutralize risks before they escalate into fires.

Dual-Layer Fire Suppression – Building on traditional gaseous fire suppression methods, CLOU has enriched its approach by incorporating rapid cooling water spray systems. This innovation effectively prevents reignition and works in synchrony with ventilation systems to diminish the concentration of flammable gases.

Explosion Protection: Active-Passive Defense – CLOU employs preemptive control measures wherein ventilation systems ensure flammable gas concentrations remain below 25% Lower Explosive Limit (LEL), thereby averting potential explosive conditions at the source, as dictated by NFPA 69. Engineered venting techniques are deployed to direct and localize any potential blast impacts, which effectively prevents chain reactions.

Active Ventilation & Explosion-Proof Design – The design impressively integrates five natural exhaust louvers and two intake mechanisms, maintaining flammable gas concentrations below 25% LEL—even during contingencies where a single intake might fail (per NFPA 69 verification). These louvers act as pressure-relief vents during an explosion, directing flames vertically to avert cross-container fire spread while ensuring constant ventilation—even in the event of power outages.

Commitment to Advancing Safety Standards

CLOU's recent innovations epitomize its dedication to raising the industry safety benchmarks. The white paper has been made accessible for download, serving as a valuable resource for developers, engineering, procurement, and construction firms (EPCs), regulators, and asset owners aiming for enhanced safety protocols and long-term reliability in storage systems.
