Long Duration Energy Storage Moves Into Focus As Renewable Capacity Expands

Long-term storage grows by 49% in 2025 despite the financing crisis

A report by Wood Mackenzie indicates that the deployment of long-duration energy storage (LDES) technologies exceeded 15 GWh in 2025, but declining venture capital investment and falling lithium battery costs are hindering their commercial viability.From ESS News Global long-duration energy storage (LDES) installations are expected to exceed 15 GWh in 2025, representing a 49% year-on-year increase, according to the latest Long Duration Energy St…

Long-duration tech still outcompeted by lithium, trade group advocates for 'valuing diversity'

Global long-duration energy storage (LDES) deployment figures soared in 2025, but newer technologies risk being outcompeted by the incumbent, lithium-ion (Li-ion).

Long Duration Energy Storage Moves Into Focus As Renewable Capacity Expands

The continued growth of renewable energy generation is increasing the need for technologies that can stabilise electricity supply. Wind and solar capacity have expanded rapidly in recent years and now represent a growing share of the overall energy mix. While this shift supports decarbonisation objectives, it also introduces variability into power systems because these sources generate electricity intermittently. Electricity networks are designe…
