Storage, the ultimate flexibility tool, is becoming one of the major challenges of the virtuous energy transition. The large-scale arrival of photovoltaic and wind power in the electricity mix makes it necessary to deploy storage solutions of more than 4 hours, "Long Duration Electricity Storage" (LDES), to compensate for the variability of these renewable energies and integrate them into the energy mix. Storage is growing thanks to batteries, hybrid or not. Storage solutions vary from large power plants to smaller units and non-dedicated equipment. Non-hybrid battery storage solutions can take the form of storage plants with several tens of MWh of power, smaller units distributed throughout the territory, or non-dedicated equipment (IRVE type). How can electricity storage help overcome the intermittency of renewable energies? How can it be optimally integrated into the energy transition strategies of countries and regions? What challenges must electricity storage overcome to be deployed on a large scale? What are the environmental implications of electricity storage, particularly in terms of battery life cycle and recycling? This round table will present the winners of an AMI, launched on June 24, to detect structuring projects on energy storage in Occitanie.
