Liquid cooling technology: revolution for storage

In recent years, the revolutionary impact of liquid cooling technology for storage of energy has been increasingly recognized in the energy industry. 

This innovative approach to energy storage has the potential to to transform significantly to how we store and use energy, offering a more efficient and sustainable for both commercial and utility-scale applications.

The use of energy storage facilities with liquid cooling it is growing because several significant benefits, some of them will be mentioned in the following topics:

Better temperature control

Liquid cooling offers better temperature distribution than air cooling. This means that liquid cooling eliminates localized “hot spots” and ensures stable battery operating temperatures. 

Precise control of temperature difference (up to ≤3℃) is critical to optimizing battery performance and safety while extending battery life.

Higher energy density

Liquid cooling systems allow for more batteries in a smaller space, achieving greater energy density. Compared to air cooling, the liquid cooling solution increases system capacity by 50% for energy storage units.

Lower energy consumption and operating costs

Liquid cooling is more efficient than air cooling, reducing the operating expenses of energy storage systems. The heat transmission coefficient of liquid cooling ranges from 1,000 to 50,000, while air cooling has a heat transfer value of only 25 to 100. 

As a result, liquid cooling systems consume much less energy than air cooling systems. Under the same average battery temperature conditions, air cooling systems consume 2 to 3 times more energy than liquid cooling systems.

Longer battery life

The stable, low operating temperature of batteries in a liquid cooling system reduces cell degradation, resulting in longer battery life and lower maintenance costs. 

Liquid cooling technology provides a more uniform temperature for the battery pack than the air cooling system, and the risk of thermal overheating is significantly lower.

Greater adaptability to operate in hostile environments

At extremely high temperatures, the temperature difference between the indoor and outdoor environments is small, causing the heat transfer performance of the air cooling system to deteriorate, leading to a decrease in cooling power. 

As a result, it cannot meet the temperature control criteria. In contrast, a liquid cooling system can operate continuously.

The Future of Liquid Cooling for Energy Storage

The increasing capacity and energy density of electricity storage systems (new power plants, off-grid energy storage) and the high performance requirements of electricity storage will lead to an increase in heat generation. 

The demand for efficient cooling for large-scale power projects with high capacity and load and frequency regulation network projects is unquestionable.
