“…A low level of solute cross mixing and water transfer across the ion-exchange membrane is expected in practice and, therefore, a significant portion of the research effort has focused on improving the performance characteristics of the separator [39][40][41][42][43]. Although cross contamination does not pose a significant health hazard and the electrolytes can be regenerated by remixing, both regeneration and membrane durability are important considerations with regard to the operational efficiency, the operational and maintenance costs and the lifetime of the system.…”

“…The company has led a research and development project funded by the Technology Strategy Board (UK government) as part of a consortium that included the University of Southampton, UK and Scottish Power, UK. Re-Fuel was launched in 2003 [83] and has designed and operated a 5 kW (6-12 h) pilot-scale stack containing 40 . Investment in the wind farm is a direct result of the Irish government's target of electricity from renewables, the majority of which will have to be met by wind power.…”

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 usage of perfluorocarbon sulfonic acid to hydrogen-oxygen fuel cell as an electrolyte is well known. Other cases are the usage of membranes of low electrical resistance to alkali battery as a separator where the membrane is made by grafting of acrylic acid to polyethylene, separator for zinc-bromine battery [190], Zn-Cl 2 , and redox-flow battery [191]. Recently, many promising polymers based on aromatic thermoplastics such as poly(ether ether ketone) (PEEK), poly(ether sulfone) (PES), poly(benzimidazole) (PBI), and polyimides (PI) have been studied, which have demonstrated …”

Membrane science is a relatively new area of applied chemistry and chemical engineering and plays a vital role in the field of alternative energy and separation applications. The field of membrane science is therefore an emerging area with enormous industrial and public health significance. Today, various kinds of separation membranes have been studied and utilized industrially in different processes including reverse osmosis, nanofiltration, ultrafiltration, microfiltration, electrodialysis, and pervaporation. Technical feasibility of all these processes largely depends on membrane and its properties. Among the separation membranes, ion exchange membranes are one of the advanced separation membranes. Therefore, this chapter addresses on different types of ion exchange membranes with reference to their preparation, properties, as well as their industrial applications. Although ion exchange membranes are broadly classified into homogeneous and heterogeneous membranes, this chapter also covers other types of ion exchange membranes such as amphoteric, mosaic, bipolar, interpolymer, and graft and block copolymer membranes. At the end, prospectives and conclusions on the ion exchange membranes have also been highlighted. The relevant literature was collected from different sources including Google sites, books, reviews, and research articles.

“…The permeation of VO 2+ ions across the membrane was determined as previously described [2,5]. The equipment for the measurement of the permeation of VO 2+ ions is shown in Figure l. One reservoir was filled with 2 mol l )1 H 2 SO 4 solution and the other with a solution of VO 2+ ions in 2 mol l )1 H 2 SO 4 solution.…”

“…The function of the membrane is not only to separate the electrolytes, but also to provide a conduction path between the two electrolytes. The logical choice of a membrane is therefore an ion exchange membrane, which may act simultaneously as an ionic conductor and a physical separator between the two electrolytes [2]. The ideal separator for the VRB should exhibit low permeation rates for vanadium active species to minimize self-discharge and to gain high current efficiency.…”

Several commercial ion exchange membranes were evaluated for application in the vanadium redox battery. The polyether membrane, DF120 cationic exchange membrane, showed the highest permeability to vanadium ions and the worst chemical stability in V(V) solution, while the divinylbenzene membrane, JAM anionic exchange membrane, showed the lowest permeability to vanadium ions and the best chemical stability in V(V) solution. In order to impart some cationic exchange capacity to the JAM anionic exchange membrane, sodium 4-styrenesulfonate was used to modify the anionic membrane by in situ polymerization. Measurements by infrared spectroscopy (IR) and cationic ion exchange capacity (IEC) verified that the modification procedure imparts cationic exchange capability to the membrane. Incorporation of cationic exchange groups to the anionic exchange membrane further results in a reduction in permeability to vanadium ions. The current and energy efficiencies averaged over 8 charge/discharge cycles of the cell with the treated JAM membrane were higher than that with the untreated JAM membrane. The current and energy efficiencies of the cell with the treated JAM membrane did not change over several charge/discharge cycles, which indicates good chemical stability of the treated membrane in the vanadium redox cell. The average efficiencies of the cell with the treated JAM membrane are higher than that with Nafion 117 over 8 charge/discharge cycles.
