The market for battery storage systems is growing rapidly. Private households in particular are currently focussing more and more on storage solutions in order to consume more of their own solar power. However, concerns about the safety of battery storage systems are an obstacle to wider acceptance and further growth of the BESS market.
Findings on risk minimisation
Even though the real fire risk of storage batteries is very low, safety concerns continue to prevent the decision in favour of such a system. In a new study, the storage manufacturer Sigenergy and the Munich-based consultancy TH Energy provide information on the current safety status of battery storage systems. The study also provides actionable insights into risk minimisation and discusses the most important measures for improving battery safety.
Customers pay for more security
The price alone should not be the only factor for investors in a storage unit. The report found a discrepancy between cost optimisation and battery safety among a large number of manufacturers. "Although standards and certifications set market standards, they often do not cover the most important safety concerns of private customers," the authors emphasise. "It becomes clear how important it is to implement additional safety concepts beyond the legal requirements in order to effectively address concerns." Customers are quite willing to pay more if the safety measures in a battery storage system go beyond the usual market standards.

Adapting norms, standards and certifications
To enable installers and investors in storage systems to make informed decisions, the report provides a detailed comparison of energy storage solutions based on their safety features. The authors also argue in favour of the further development of norms, standards and certifications. This is the only way they can keep pace with technological progress and new safety concerns. The project partners assume that storage system providers will be encouraged to adopt the security measures described in the report. This will increase market pressure for stricter security regulations across the industry.

Gaining more trust from customers
With the report, Sigenergy aims to redefine battery safety and endeavour to improve safety standards in order to gain consumer confidence, explains Thomas Hillig, co-author of the report and director of consultancy firm TH Energy. By disclosing technologies, findings from extensive testing and real-world operation of its own battery storage systems, the company aims to set a higher benchmark for safety in the storage market and drive positive change across the industry. "This comprehensive safety report is a call to action for all players in the battery energy storage sector to prioritise safety and innovation. Together, we can ensure the continued growth and sustainability of the storage market while protecting the well-being of consumers," emphasises Tony Xu, Managing Director of Sigenergy.
