Recent research from RWTH Aachen University in Germany reveals astonishing insights into the fire risks posed by battery energy storage systems in homes. The study, published in October 2024, indicates an annual fire risk of just 0.0049%. The researchers unveiled their findings at an event in Berlin hosted by the Federal Energy Storage Systems.
To gauge fire incidents, the team dove into media reports and compiled a comprehensive database of occurrences. By the end of November 2023, they documented 36 fire incidents linked to these systems over the past year, with a noticeable uptick to 56 incidents this year, coinciding with a surge in solar home storage installations—approximately 1.6 million systems across Germany.
The research focused exclusively on fires directly caused by battery systems, excluding factors like management system faults or user mistakes. The analysis revealed that most fires occurred from noon to 4 PM and were increasingly prevalent during spring, likely as systems resumed operation after winter dormancy.
When comparing household appliance risks, fire probabilities for battery systems stood at 0.049%, slightly higher than photovoltaic systems at 0.0014%. The study also highlighted that electric vehicles pose a fire risk of 0.024%, underscoring that battery storage systems are relatively safe overall.
This extensive research aims to quell consumer concerns surrounding battery storage systems and to promote informed discussions about their safety.
Revolutionary Study Reveals Battery Storage Systems’ Fire Risk is Surprisingly Low
Understanding Fire Risks in Battery Energy Storage Systems
Recent findings from RWTH Aachen University in Germany have brought to light critical insights concerning the fire hazards associated with battery energy storage systems in residential settings. The research, released in October 2024, presents an incredibly low annual fire risk of just 0.0049%, emphasizing the overall safety of these systems.
Key Findings from the Research
To assess the fire incidents related to battery systems, researchers analyzed media coverage and compiled a detailed database. As of November 2023, they recorded 36 fire incidents linked to battery systems in homes. This figure has risen to 56 incidents in 2024, which coincides with the rapid increase in residential solar battery installations—approximately 1.6 million systems across Germany.
The study focused solely on fires directly attributed to battery storage systems, purposefully excluding other potential causes such as management system failures or user errors. Notably, it was found that the majority of fires occurred between noon and 4 PM, particularly escalating during the spring months as systems became more active after the winter season.
Comparative Risk Analysis
When looking at fire risks among common household appliances, the research indicates that battery systems present a fire probability of 0.049%. In comparison, photovoltaic solar panels are associated with a significantly lower fire risk of 0.0014%, and electric vehicles (EVs) have a fire risk of 0.024%. These findings suggest that while there is some fire risk, battery storage systems are relatively safe in the broader context of household technology.
Implications for Consumers and Market Trends
This research serves a dual purpose: to reassure consumers about the safety of battery storage systems and to promote a nuanced understanding of their risks. With over 1.6 million installations in Germany, the trend towards embracing renewable energy sources through battery storage is likely to continue, fueled by a growing awareness of energy efficiency and sustainability.
