What happens if a solar farm catches fire? Europe’s biggest battery test centre is finding out
Battery ‘torture testing’ simulates car washes, sandstorms and wildfires for the benefit of the energy transition.
At Europe's largest battery testing centre located in Eastern Germany, researchers subject batteries to extreme conditions to evaluate their performance. These tests include exposure to high and low temperatures, dust storms, vibrations, and even fires. As Thomas Hucke, the head of DEKRA, explains, this rigorous testing is essential to ensure the safety and reliability of batteries used in electric vehicles as well as stationary energy storage systems.
These stationary energy storage systems, primarily designed for renewable sources like solar and wind power, are crucial for the energy transition. They serve as intermediate storage for the electricity generated by these intermittent sources, providing a stable and safe supply.
Hucke emphasizes that the European Union has established a Battery Regulation that mandates specific tests on batteries to guarantee safety. This regulation focuses on sustainability, the entire supply chain, and, most importantly, consumer safety. Batteries are tested in various ways, including crushing, burning, and simulating accidents or improper charging and discharging.
A significant concern is the potential for major fires in buffer electricity storage facilities at solar or wind farms. While extreme heatwaves like the scorching summer Europe experienced can put such facilities at risk, the test centre has measures in place to handle this scenario. This includes pressure relief flaps and a complete flue gas scrubbing system that extracts dangerous gases in emergencies.
As Europe rapidly increases its use of wind and solar power, battery test centres become increasingly vital. They ensure that this renewable energy can be stored safely and effectively, making the energy transition a reality. DEKRA's efforts in this field align with global standards and regulations, placing safety first in the rapidly evolving world of renewable energy storage.
