Abstract: Apparatus and associated methods relate to a neutralization and circulation module (NCM) configured to generate a combustion suppressant stream from a flammable intake stream. In an illustrative example, the NCM includes an intake port and an output port, each in fluid communication with a chamber containing (electro)chemical energy storage units capable of emitting combustible gases. The NCM may, for example, include a reactor in fluid communication between the intake and output port. The reactor may, for example, selectively apply an oxygen-containing stream from an oxygen source to the intake stream to generate, from the stream containing combustible gases, a combustion suppressant gas stream that is discharged through the output port into the chamber such that an upper flammability limit approaches a lower flammability limit in the chamber. Various embodiments may advantageously eliminate a flammable regime in a chemical energy storage environment.

Abstract: Apparatus and associated methods relate to a passive automatic injector reactor system (PAIRS). In an illustrative example, an energy storage enclosure may contain energy storage modules (e.g., batteries) releasing target gas(es) (e.g., toxic, flammable). The PAIRS may, for example, include an injector in fluid communication with the enclosure. The injector may, for example, passively direct target gases released from the enclosure to a mixing area where supplemental gas(es) are entrained with the target gases to create a target gas air mixture that is directed to a reactor. The reactor may, for example, utilize one more chemical, physical, and/or physiochemical processes to convert the target air gas mixture into a processed gas before release. Various embodiments may advantageously prevent fire, explosion, and/or the release of toxic gas from batteries.
