Global long-duration energy storage (LDES) deployment figures soared in 2025, but newer technologies risk being outcompeted by the incumbent, lithium-ion (Li-ion).
Australian mining giant Fortescue has claimed to have secured large-scale battery storage at pricing levels not previously seen in Australia, according to CEO Dino Otranto.
The costs of certain long-duration energy storage (LDES) technologies are expected to decline by around 37% on average by 2030, according to a new study.
Lithium-ion cell prices will fall by around 46% between now and 2029, according to new analysis from Guidehouse Insights, reaching US$66.6 per kWh by that time.
A new report from the US National Renewable Energy Laboratory (NREL) aims to track cost trends in residential PV-plus-storage, help stakeholders to identify potential cost-reduction opportunities and illuminate barriers that exist to the technology’s widespread deployment.
