Wärtsilä ESS fire safety testing showed battery smoke is no worse than other smoke

technical group Wärtsilä has completed UL 9540A fire safety testing. grid solve quantum Energy Storage System (ESS).

Under the supervision of Wärtsilä’s fire protection partners and stakeholders (including the Fire Risk Alliance (FRA), Energy Safety Response Group, and Energy Security Administration), the trials were completed at the facility in Piqua, Ohio, and were supervised by the Energy Safety Response Group. operated.

Under test conditions, a fire was ignited in a ventilated unit and allowed to burn spontaneously for over 8 hours. The results showed that the fire was contained within the originating unit, the door remained closed, and no propagation from unit to unit occurred.

As part of the test, FRA collected plume gas data to assess the potential environmental impact of the smoke emitted by the ESS fire. The FRA analysis concluded that smoke from ESS fires is no worse than fires involving ordinary consumer products in terms of environmental impact.

“Wärtsilä’s custom testing is the ideal way to demonstrate that fires will not propagate between ESS enclosures or from string to string. For as long as possible, it indicates that a fully engaged fire is unlikely to spread beyond the originating force,” said Dr. Noah Ryder, Managing Partner, Fire & Risk Alliance.

“As the risks posed by energy storage systems are better understood by AHJ, the desire to incorporate more data into safety analysis requires greater scale and evolution of testing. Test results, such as large-scale fire tests, help inform this process and, collectively, enable better analysis and satisfaction of code requirements,” said Nick Warner, Energy Safety Response Group Lead. said. “In the case of Wärtsilä, once the system is fully engaged, [fully on fire]The risk to nearby forces was minimal and could be managed by a well-trained fire department with proper planning and support. ”

Wärtsilä’s GridSolv Quantum is a fully integrated, modular and compact ESS. In April 2022 he received UL 9540 certification and in February 2023 he completed UL 9540A unit level performance testing. Wärtsilä’s GridSolv Quantum uses Lithium Iron Phosphate (LFP) batteries.
