Iron redox flow batteries are inherently safer than vanadium redox flow batteries.
All types of redox flow batteries - in difference to lithium ion batteries of the NMC (nickel manganese cobalt) type - can't have thermal runaway; lithium iron phosphate batteries, which are typically used for grid/home storage are safe from thermal runaway as well.
