The LDES Council’s policy team discusses the role of policy and markets in scaling long-duration energy storage globally with ESN Premium.

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

Now is the moment for long-duration energy storage to become a key pillar of the energy transition, writes LDES Council CEO Julia Souder.

Envision Energy is preparing to reveal lithium-ion (Li-ion) battery energy storage system (BESS) technology for long-duration applications.

Mark Croudace, executive representative of the LDES Council, questioned what technologies will join lithium-ion on the energy storage podium.

The capabilities of lithium-ion battery storage in providing long-duration energy storage to global energy systems should not be overlooked, write Kotub Uddin and Sam Secher of Envision.

Global decarbonisation targets are impossible without increasing the pace of long-duration energy storage (LDES) adoption 50 times over by 2040, according to the LDES Council.

Penny Sharpe, the New South Wales energy minister, has announced plans to legislate a new long-duration energy storage (LDES) target for the Australian state of 28GWh by 2034.

The consultation in New South Wales, Australia, on reducing the definition of LDES to 4-hours sparked mixed reactions in the energy sector.

Over the past few days, non-lithium long-duration energy storage (LDES) technology providers have made a plethora of announcements.
