5. Conclusion

In conclusion, energy storage is becoming an essential lever in the management and enhancement of power grids, particularly in the context of the energy transition and the growing integration of renewable energies. Faced with the intermittent nature of renewable energy sources such as wind and solar power, energy storage enables us to better manage the balance between supply and demand, thereby contributing to the stability and reliability of power grids. By making it possible to store surplus energy produced during periods of high production and release it during peak consumption, storage plays a key role in the flexibility services that are essential to the smooth operation of the grid.

Storage technologies, whether batteries, pumped storage systems, compressed air or emerging solutions such as hydrogen, have demonstrated their potential to provide solutions tailored...
