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.

Global average lithium-ion battery prices have fallen 20% to US$115 per kWh this year, going below US$100 for electric vehicles (EVs), BloombergNEF said.

A large-scale hybrid project has been connected to the grid in China, combining BESS and supercapacitor technology to provide numerous services to the grid including black start.

We get the reaction from other BESS suppliers, consultancies, research firms, optimisers, investors and IPPs to BYD launching a BESS using sodium-ion battery cells, a technology many see as a potential competitor to lithium-ion.

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

Energy-Storage.news hears from the CEO of American Energy Storage Innovations (AESI), about its BESS technology, battery cell strategy, manufacturing in East Asia and the “shocking” price of manufacturing in the US and buying US-made cells.

SolarEdge interim CEO Ronen Faier has spoken about the closure of the company’s utility-scale battery storage manufacturing business.

SolarEdge has closed its utility-scale battery storage division, resulting in a layoff of roughly 12% of its total workforce.

Chinese EV giant BYD has launched what an executive claimed is the ‘world’s first high-performance’ sodium-ion BESS product, using its proprietary form factor Long Blade Battery cell.

Callum McGuinn, partner at European intellectual property (IP) firm Mewburn Ellis, rounds up the major advancements in battery cell technology that BESS industry sources should be aware of.
