Energy Storage Safety - Key Risk Factors

Energy storage systems are becoming increasingly common solutions in the energy sector, for both households and commercial sectors. However, with their rising popularity, certain risks associated with their use also emerge. It is therefore worth examining the main risk factors and ways to minimize potential hazards.

Lithium-ion Technology and Design Flaws

The most commonly used technology in energy storage is lithium-ion technology, known from everyday devices like smartphones. Unfortunately, as numerous incidents show, lithium-ion batteries are not free from design flaws that can lead to overheating and even explosions. In the case of energy storage systems, where thousands of cells are used, the risk of such design flaws is higher, underscoring the importance of conducting rigorous quality tests during production.

Overheating and Temperature-Related Issues

Another significant risk factor is the overheating of energy storage systems. Controlling the temperature of both the battery itself and the surrounding environment is crucial for avoiding undesirable incidents. Sudden temperature spikes can lead to thermal runaway in battery cells, increasing the risk of fire.

Installation Errors and Mechanical Damage

Errors during the installation of energy storage systems, such as improper connections or unsuitable placement, can lead to potentially dangerous situations. Moreover, even minor mechanical damages can cause serious operational issues with the battery, highlighting the need for caution when handling energy storage systems.

Random Events and Lack of Optimal Ventilation

Energy storage systems may be susceptible to random events such as fires or flooding, which increase the risk of damage to the cells. Additionally, a lack of proper ventilation can lead to the device overheating, presenting another hazard.

Safety Measures and Risk Minimization

To minimize the risk of energy storage failures, a range of safety measures exist, such as BMS systems, cell auto-balancing functions, double-skinned enclosures, or appropriate ventilation systems. Furthermore, it is important to use proper overcurrent protection and power supply cables as well as to install gas detectors near the system.

Summary

Energy storage systems are a key element in the energy transition, allowing for the storage of electrical energy to enhance grid stability and improve energy efficiency. Despite the risks associated with their use,

appropriate precautions can significantly minimize these hazards. Therefore, implementing safe practices and utilizing appropriate safety measures is crucial for ensuring the safe and efficient operation of energy storage systems.
