From patchwork to harmony: The case for aligning standards in energy storage
Improving safety and security does not require lowering standards, but it does require aligning them. This is where an industry-led approach – one that brings together manufacturers, developers, validators and insurers – comes in, writes Ken Stewart, senior manager ESS at Sungrow Europe.

Why BESS insurers are sweating transformers and contractor errors over battery fires
The BESS insurance risk profile is shifting. In an exclusive interview, Tokio Marine GX underwriter Michael Carrington explains why insurers are looking past battery fires and sweating over supply chain bottlenecks, high-voltage transformers, and costly EPC integration errors.
Australian regulator ramps up battery inspections
Solar battery installers have been warned to “do it once and do it well” as the number of batteries installed across Australia under the federal government’s Cheaper Home Batteries Program surges past the 250,000 milestone, delivering a combined 6.3 GWh of capacity.
Comparing safety profiles of lithium-ion, sodium-ion and solid-state batteries
New research finds that battery safety rankings are not universal but highly dependent on application scenarios, and shows that LFP batteries can emit high levels of hydrogen fluoride, challenging their reputation as the “safest” chemistry.
Hithium says ‘world’s first’ open-door first test of its 6.25 MWH BESS was completed
Hithium has released results from a large-scale fire safety test of its 6.25 MWh battery energy storage system (BESS) it calls "∞Power". The so-called open-door test, supervised by UL Solutions, subjected the unit to maximum oxygen supply conditions to evaluate thermal runaway risks in high-capacity 1175 Ah cells.

China to conduct comprehensive safety overhaul of battery storage facilities
China's regulators are reportedly considering a comprehensive fire safety inspection and upgrades of operating energy storage facilities. For older storage stations, enhancing fire safety measures will significantly increase non-technical costs, potentially up to CNY 0.2 per Wh ($0.028/Wh).

Volytica, Sinovoltaics launch new analysis service for 100% battery pack review at factory
The newly launched BESSential analysis goes deeper than traditional Factory Acceptance Testing (FAT), which is performed at the container level. The service evaluates each battery energy storage system pack down to the cell level and detects and corrects thermal, electrical, and capacity imbalance issues. The analysis is performed directly at the factory, reducing the risk of post-deployment setbacks.
UL Solutions introduces new testing protocol for residential battery storage systems
The latest test method addresses the fire propagation behavior of a residential battery energy storage system if a thermal runaway propagation event leading to an internal fire were to occur during the system’s lifetime.
