- The need for storage is still poorly understood, as it depends on changes in demand and the energy mix, and therefore on meteorological data. An evaluation of a minimum of 10 to 20 years of historical data would be necessary to identify the probabilities and durations of dunkelflaute phenomena (a period with low wind and sunshine) [3], for example. On the other hand, demand response capacity - for example via the management of vehicle charging - could provide more flexibility on the demand side.
- Different technologies allow long-term storage (from several hours to seasonal) on a large scale [3]. Pumped hydro plants are a classic solution, but their potential is limited, or the technologies need to be adapted, as with marine pumped hydro plants. Hydrogen - or its derivatives - is a potential solution, but it cannot be based on geological storage (salt caverns, etc.) due to its absence in La Reunion Island. Other technologies such as iron-air batteries, with low density but very low cost, may emerge in the future [5]. Apart from the questions of technical feasibility, costs and performance, the question of the environmental impacts (emissions, biodiversity, resources, etc.) of these technologies must also be considered.
- Another approach would be to use distributed storage, for example in the form of residential batteries or even vehicle-to-grid (V2G). However, the coordination of these resources is much more complex because it relies on a large number of equipment, can impact users and raises the question of the underlying business model. The feasibility of this approach is therefore uncertain.
- In terms of management, the simultaneous consideration of short-term (minute to hour) and long-term (several years) dynamics poses problems of computation time, especially when the ageing of components is considered [4].
