“…Both of these factors effectively set a limit on the energy density of the cell (25-35 W h kg −1 ) [5], which is relatively low in traction applications. Despite these limitations, the theoretical (thermodynamic) standard cell voltage for the overall discharge reaction is favourable (+1.26 V) [44]. Excluding pumping costs, the energy density also has a reduced significance for stationary uses, especially if the infrastructure resources required for the establishment and operation of large-volume electrolyte reservoirs are readily available.…”

SUMMARYThe commercial development and current economic incentives associated with energy storage using redox flow batteries (RFBs) are summarised. The analysis is focused on the all-vanadium system, which is the most studied and widely commercialised RFB. The recent expiry of key patents relating to the electrochemistry of this battery has contributed to significant levels of commercialisation in, for example, Austria, China and Thailand, as well as pilot-scale developments in many countries. The potential benefits of increasing battery-based energy storage for electricity grid load levelling and MW-scale wind/solar photovoltaic-based power generation are now being realised at an increasing level. Commercial systems are being applied to distributed systems utilising kW-scale renewable energy flows. Factors limiting the uptake of all-vanadium (and other) redox flow batteries include a comparatively high overall internal costs of $217 kW −1 h −1 and the high cost of stored electricity of ≈ $0.10 kW −1 h −1 . There is also a low-level utility scale acceptance of energy storage solutions and a general lack of battery-specific policy-led incentives, even though the environmental impact of RFBs coupled to renewable energy sources is favourable, especially in comparison to natural gas-and diesel-fuelled spinning reserves. Together with the technological and policy aspects associated with flow batteries, recent attempts to model redox flow batteries are considered. The issues that have been addressed using modelling together with the current and future requirements of modelling are outlined.

“…The vanadium redox flow battery (VRFB) is one of most promising large-scale storage technologies to meet the requirement of grid load-smoothing and smooth output of renewable energy sources, due to its characters like high performance, long cycle life and flexible design [1][2][3]. The cell stack is assembled by several single cells, which are connected in series by bipolar plates to meet the voltage requirement [4].…”

A redox flow battery is an electrochemical energy storage device that converts chemical energy into electrical energy through reversible oxidation and reduction of working fluids. The concept was initially conceived in 1970s. Clean and sustainable energy supplied from renewable sources in future requires efficient, reliable and cost-effective energy storage systems. Due to the flexibility in system design and competence in scaling cost, redox flow batteries are promising in stationary storage of energy from intermittent sources such as solar and wind. This chapter covers basic principles of electrochemistry in redox flow batteries and provides an overview of status and future challenges. Recent progress in redox couples, membranes and electrode materials will be discussed. New demonstration and commercial development will be addressed.
