Another year draws to a close, allowing us to reflect on the fantastic energy storage content from Solar Media’s journal PV Tech Power.

Another edition of news in brief, this time from regulators in the US states of Connecticut and Oregon and flow battery maker Quino Energy.

Eos Energy Enterprises has signed a joint development agreement (JDA) with FlexGen Power Systems to develop a fully integrated battery energy storage system (BESS) solution using Eos’ zinc batteries and Flexgen’s Energy Management System (EMS).

Engie has signed an ‘energy storage as a service’ contract with technology provider Energy Dome for a long-duration energy storage (LDES) project in Sardinia, Italy.

Vanadium flow batteries could be a workable alternative to lithium-ion for a growing number of grid-scale energy storage use cases, say Matt Harper and Joe Worthington from Invinity Energy Systems.

Technology provider Rongke Power has completed a 175MW/700MWh vanadium redox flow battery project in China, the largest of its type in the world.

Western Australia’s GreenTech Hub, dedicated to supporting emerging green technologies, will explore advanced energy storage systems as its first challenge.

New vanadium redox flow battery technology from Invinity Energy Systems makes it possible for renewables to replace conventional generation on the grid 24/7, the company has claimed.

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.

Western Australia has revealed a new long-duration vanadium flow battery pilot in the town of Kununurra exploring the use of the technology in microgrids and off-grid power systems.
