A Marlborough, Massachusetts, startup has made an organic flow battery that can rival lithium -ion packs for grid-level storage, according to TechCrunch. The innovation provides for a variety of perks, including a "capital cost [that] should be ultra low," XL Batteries co-founder Tom Sisto said.
[pdf] Battery energy storage systems configured within small rooms, enclosures, or containers where flammable gas can exceed 25% of the lower flammable limit (LFL) should be protected with either explosion prevention/ suppression or deflagration venting designed and installed within requirements of NFPA 69 Standard on Explosion Prevention Systems and NFPA 68 Standard on Explosion Protection by Deflagration Venting.
[pdf] A flow battery consists of tanks, a pump system and battery cells, also known as a battery stack. The tanks contain a liquid electrolyte solution that serves as a storage medium. The electrolyte is pumped through the battery cells to charge and discharge the battery, binding electrons.
