HEFEI – October 21, 2026 -- Sungrow's PowerTitan 3.0 battery energy storage system contained a thermal runaway event that reached 1259.8°C without spreading to adjacent containers or a medium-voltage substation, becoming the first stacked-cell BESS with an AC-block design to complete a large-scale fire test under UL 9540A: 2026 and CSA/ANSI C800-2025.

UL Solutions conducted the test. Fire Risk Alliance witnessed it and Jensen Hughes observed it. All three PowerTitan generations, 1.0 through 3.0, passed their large-scale fire tests on the first attempt.

Test layout replicated a utility-scale installation with 28.56 MWh of storage

The setup mirrored a block-level utility-scale layout. It included 28.56 MWh of fully liquid-cooled PowerTitan 3.0 units and a 7.4 MW medium-voltage substation. PowerTitan 3.0 combines stacked high-energy-density cells and the DC/AC power converter unit in a single 20-foot container.

Toronto – October 21, 2026 -- HiTHIUM, which says it has surpassed 200 GWh in cumulative delivered energy storage capacity, has entered the Canadian market with 4-hour and 8-hour lithium-ion battery energy storage systems (BESS) and a new 4 MWh sodium-ion product designed for extreme cold.

HiTHIUM builds Canadian footprint across six locations

Toronto serves as the main hub for Canadian operations. The company also runs subsidiary offices in British Columbia and Alberta, and operating sites in Quebec, Yellowknife and Fort Smith, said Mizhi Zhang, President of Global Business.

HiTHIUM is targeting a market where installed Canadian storage is expected to double between 2025 and 2027. Total wind, solar and storage capacity is on track to reach 50 GW by 2035, according to the company.
