Construction is underway on a 100MWh thermal energy storage project in Finland, using the same ‘Sand Battery’ technology as a 8MWh system which came online in 2022.

A 100MW thermal solar and molten salt energy storage system in Xinjiang, China, is set to be completed and grid-connected by the end of the year, part of a project which has deployed conventional solar PV.

A new research centre ‘uniquely equipped’ to evaluate energy storage technologies has opened at Pacific Northwest National Laboratory (PNNL) in Washington, US.

Delays in product development, high commodity prices and investors pulling out were behind some of the most recent bankruptcies in the ESS battery technology space, which include Nilar, AMTE and Ambri.

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

Some long-duration energy storage (LDES) technologies are already cost-competitive with lithium-ion (Li-ion) but will struggle to match the incumbent’s cost reduction potential.

Editor Andy Colthorpe speaks with Long Duration Energy Storage Council director of markets and technology Gabriel Murtagh.

Hyme Energy has inaugurated a molten hydroxide salt energy storage project in Denmark, the first such deployment in the world, it claimed.

NGK Insulators will provide 72 containerised sodium-sulfur (NAS) battery storage units to a green hydrogen production plant in Germany.
