Renewable energy sources require large-scale, stationary energy storage systems to balance out fluctuations in energy generation (6.5 GW from solar panel in France at 2015 and 8.5 GW from wind turbine in 2014, expected to exceed 20 GW at 2020) as well as to reduce the use of the fossil fuels and consequently to reduce the pollutant production as well as the CO2 emissions. VSL ( Vanadium- Liquid-Solid) project will advance the development of one of the most promising storage systems i.e. redox-flow batteries which concerns the conversion of “renewable” electrical energies in to chemical form and the reverse process i.e. the recovery of the stored electrical energy. More precisely, the energy must be stored via a redox reaction into ‘electroactive chemical compounds’ present in solutions; these solutions are stored into high volume storage tanks (ST) and flow across electrochemical reactor (ER), the resulting system was named redox flow battery.
