EPRI, Southern Company and Storworks have completed testing of a concrete thermal energy storage pilot project at a gas plant in Alabama, US, claimed as the largest of its kind in the world.

Saudi Arabian oil firm Aramco has entered into a memorandum of understanding (MOU) with Rondo Energy, a thermal energy storage company, following an equity investment.

RayGen, a startup developing long-duration energy storage (LDES) technology designed for pairing with renewable energy installations, has raised investment to kick off a Series D funding round.

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

The European Commission has approved a €1 billion (US$1.1 billion) state aid measure for Greece to support two solar-plus-storage projects.

US$150 million has been raised in a Series B by Antora Energy, a US-based startup with a novel ‘thermal battery’ technology claimed to be suitable for decarbonising industrial processes.
