Demand for battery energy storage systems (Bess) is increasing as the world is moving towards renewable energy. However, heat treatment is a big challenge in large batteries. Excessive heat reduces efficiency, shortens lifetime and increases safety risks, including thermal release. For years, air cooling was the standard, but as the energy storage capacity is expanded, it proves to be inadequate. Liquid cooling now appeared as a preferred solution that offers better heat distribution, efficiency and reliability.
Why does liquid cooling replace air cooling?
Air cooling works by circulating the battery cells, but as the battery systems increase higher, this method does not prevent battery degradation and power reduction. The liquid cooling, on the other hand, uses the coolant directly from the battery cells, ensuring the temperature distribution. This not only prevents overheating, but also increases efficiency, improves charging speed and extends battery life. As a result, liquid cooling becomes a standard for storing grid battery, data centers and electric vehicles (EV).
Market growth: $ 24.51 billion
According to BIS Research, the liquid cooling market of the located Bess is set to enormous growth. The $ 4.23 billion market in 2024 is expected to reach $ 24.51 billion by 2033 and will increase by 21.55%CAGR. This rapid expansion is controlled by the increasing need for renewable energy storage, rising solid state batteries and increasing security concerns in large -scale facilities.
The latest developments that encourage the adoption of liquid cooling
In June 2024, the Highview Power provided an investment of £ 300 million for the construction of a 50mW/300 MWH liquid air energy storage facility in Carrington in the UK. This project highlights the need for advanced cooling systems in large -scale energy storage, ensuring stable operations and better efficiency.
Meanwhile, Mercedes-Benz, in cooperation with Factorial, develops solid state batteries that are more energy density but generate more heat. As a result, liquid cooling is essential for a safe and effective battery.
Another breakthrough is the immersed cooling, where the battery components are completely immersed in the dielectric liquid. Unlike conventional liquid cooling, which circulates the coolant around the cells, the immersion cooling completely eliminates hot spots, thus an attractive solution for high -performance applications.
Why liquid cooling is the future?
One of the biggest benefits of liquid cooling is that it is capable of efficient distribution of heat, preventing thermal fluctuations that can damage the battery performance. This ensures higher energy efficiency, allowing batteries to be stored and emptied more efficiently.
Security is another critical factor. The thermal release – the leading cause of the battery fire – is much less likely to have liquid cooling as the battery temperature is stable. In addition, liquid cooling allows for more energy density in compact systems, making it ideal for storing a grid -sized battery, where the space is restricted.
Despite these benefits, liquid cooling requires higher prior costs and regular maintenance to prevent leaks. However, long -term benefits are above the challenges as better performance and security leads to lower operating costs and extending battery life.
Sizing with liquid cooling
As the acceptance of renewable energy accelerates, efficient and safe battery storage becomes a priority. Governments, utilities and private companies invest strongly in liquid cooling technology to improve energy storage performance.
As the market value is expected to reach $ 24.51 billion by 2033, liquid cooling is no longer an emerging trend – this is necessary. Effective heat management is essential for future energy solutions for the storage of the grid, electric vehicles, or Advanced battery systems, and liquid cooling.
