Iron flow battery
An iron flow battery is a redox flow battery that stores energy in iron, salt, and water electrolytes, offering cheap, non-flammable, long-duration stationary storage for renewable-heavy grids.
Iron-chromium redox flow battery
The iron-chromium redox flow battery (ICRFB) is a redox flow battery that stores energy in acidic iron and chromium electrolytes, invented at NASA in the 1970s.
Organic flow battery
An organic flow battery is a redox flow battery storing energy in carbon-based organic molecules instead of metal ions, promising cheaper, tunable chemistry than vanadium systems.
Quinone flow battery
A quinone flow battery is a redox flow battery whose energy-storing electrolytes are quinones, organic molecules built from earth-abundant elements, first demonstrated at Harvard in 2014 and now being commercialized by Quino Energy.
Redox targeting
Redox targeting is an energy-storage method in which redox mediator molecules shuttle electrons between an electrode and a solid active material not wired to the circuit.
Redox-active polymer flow batteries
Redox-active polymer flow batteries are aqueous organic redox flow batteries storing charge in redox-active polymers, first demonstrated in 2015 with dialysis membranes and a sodium chloride electrolyte.
Redox-targeting flow battery
A redox-targeting flow battery, also called a redox-mediated or redox-shuttle flow battery, is a redox flow battery that stores most of its energy as solid material held in the tanks.
Semi-solid flow battery
A semi-solid flow battery (SSFB) is a flow battery that stores energy as particles suspended in a liquid electrolyte, first demonstrated at MIT in 2011.
Zinc-bromine battery
A zinc-bromine battery is a rechargeable hybrid flow battery that plates zinc during charging, first commercialized by Exxon in the 1970s and used for stationary energy storage.
Zinc-iron flow battery
A zinc-iron flow battery is an aqueous redox flow battery using zinc and iron redox couples with electrolytes pumped from external tanks, suited to large-scale energy storage.
Zinc–iodide flow battery
The zinc–iodide flow battery, also called zinc–polyiodide flow battery, is a hybrid redox flow battery storing energy by plating zinc and converting iodide to triiodide.
