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.

While lithium-ion is rapidly racing ahead to become the “de facto grid storage solution” and is the most popular technology choice by far, vendors of other types of batteries are also targeting the market, with varying degrees of success.

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.

An energy storage market and tech analyst has told Energy-Storage.News a decision by flow battery maker Redflow to shift focus away from the residential market signals that it is “highly unlikely” the technology can compete with lithium-ion in that space.

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.

Redox flow battery EV maker nanoFlowcell is planning a stock market flotation on the back of a major restructuring process.

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.

Flow battery manufacturer ViZn Energy Systems has won a contract to provide a 128kW/320kWh system for a US department of energy project.

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”.
