Four months after its CEO declared to Energy-Storage.News that hybrid vanadium redox flow-lithium systems would be the “optimal” way to deliver multiple applications for energy storage, redT has delivered equipment to its first such project.

One of Germany’s largest utilities wants to build what it says could be the biggest ‘battery’ in the world to date – using underground caverns filled with saltwater as a giant redox flow energy storage system.

Hybrid systems that combine high power technologies such as lithium-ion and long duration, high energy redox flow energy storage is “where the market will go”, the CEO of a vanadium ‘flow machine’ provider has said.

A containerised flow battery dubbed the ‘largest’ such system in the US has been matched for size by another system dedicated last week in Snohomish, Washington.

Property and infrastructure group Lendlease has signed a joint venture agreement (JVA) to deliver solar, battery storage and microgrid projects across Australia with Carnegie Clean Energy.

Vanadium redox flow technology provider redT energy has passed its G59 pre-testing for its 15kW / 240kWh vanadium flow energy storage systems, which are located at the Power Networks Demonstration Centre (PNDC) in Cumbernauld, Scotland.

Energy storage provider Schmid Energy Systems has signed a memorandum of understanding (MOU) with vanadium supplier VanadiumCorp Resource to jointly work on mineral extraction and developing vanadium electrolyte.

Anthony Price of consultancy Swanbarton previews the International Flow Battery Forum in Germany with a quick primer on the technology, its uses and some of the players attending the event.

Energy storage could have a ‘highly critical’ role to play in emerging economies, Aloke Gupta of Imergy Power Systems says. Gupta, who was previously with California’s Public Utilities’ Commission, the state’s regulator, talks about the uses and applications of micro-grids, from his vantage point of view as a flow battery and storage system maker.

A Silicon Valley-headquartered flow battery maker will provide energy storage for telecommunications networks in China, replacing diesel use in a pilot programme ahead of “wide-scale deployment”.
