Energy storage systems are emerging as a valid viable solution in enhancing electric grid stability and supporting renewable energy use. Different types of battery technologies show performances suitable for providing multiple grid services such as peak demand response, frequency and voltage regulation, load-levelling, backup power, and balancing the effects of locally-intermittent renewable sources (i.e. wind and solar). However, it’s an accepted common concept that no ‘one size fit all’ solution is currently available, able to be the best one in a wide range of services and applications. Therefore, HESS are becoming an interesting approach to realize storage systems able to give both energy and power intensive responses by combining and using (by proper management algorithms) the best performances offered by two or more storage technologies. In this project two totally different electrochemical storage systems will be combined to fulfil this scope: the first one is constituted by an innovative organic redox-flow-battery (RFB) developed by Kemiwatt, while the second one uses a Lithium Titanate Oxide (LTO) battery, produced by Toshiba, which represents an interesting chemistry among lithium-ion batteries.
