Global LDES cumulative installed capacity 2025-2040
Systems with a storage duration of up to 24 hours will make up the largest share of installed capacity.
The cumulative installed capacity of long duration energy storage (LDES) is estimated to grow significantly in the coming decades, to reach between 1.5 and 2.5 terawatts by 2040. This would be an increase of at least 50-fold in comparison to the 30 to 40 gigawatts estimated for 2025.
