So far, most of the studies have analyzed lithium-ion batteries (LiBs) as an option for energy storage in island settings. Rampazzo et al. [ 20] assesses the benefits of the installation of lithium-ion batteries in the island of Ventotene (Italy).
Battery energy storage The main function of the battery system is to store the surplus of electrical energy production introduced by variable renewable sources and use it during hours of low renewable supply. For these applications, batteries usually operate with a daily cycle of charge and discharge [ 57 ].
The total production of energy slightly increases when the storage is present, because of the losses due to the storage cycle, but this is counterbalanced by the large reduction in curtailed energy. Thereby, the implementation of a storage system allows the renewable share to reach 46%.
Conclusion The techno-economic analysis of two battery technologies reveals that the benefits of a storage project are remarkable both in terms of increased use of indigenous resources, and in terms of reduced fossil fuel imports.
