Flow batteries have so far, failed to live up to the disruptive potential they promise, a new report says, but authors Alex Eller and William Tokash at Navigant Research have identified 12 leading vendors in the nascent field, based on metrics of strategy and execution.

14D to add unique heat and electricity storage solution to solar PV and CST project in South Australia, offering grid stability and powering greenhouses with stored heat.

Defense and aerospace giant Lockheed Martin wants to be the first disruptive company of the flow battery era, with the expectation that its first devices will go into series production before the end of this year.

By the middle of the 2020s, using hybrid ‘portfolios’ of batteries and renewable energy sources will economically outperform existing gas power plants, while the combination of technologies is already cost-competitive with building new gas plants, a new report from the US-based Rocky Mountain Institute has said.

Softbank Group’s SB Energy subsidiary is among investors that contributed to a successful US$30 million Series C funding round for ESS Inc, a US-headquartered manufacturer of iron flow batteries that use a proprietary saltwater electrolyte.

Reports of Eos’ aqueous zinc battery being paired with small modular nuclear reactors (SMNRs) in a joint venture (JV) with Holtec appear to have been greatly exaggerated, according to an Eos representative.

A legislative package for energy storage research and development has been welcomed by the US Energy Storage Association after receiving approval from the Senate Energy and Natural Resources Committee.

NEC will be using so-called ‘liquid metal’ batteries produced by Ambri in projects that could require more than four hours’ duration of energy storage, the company announced at SPI / ESI this week.

While lithium-ion enjoys the most media and customer interest at the moment, alternative technologies for storing energy could become competitive – if investors are willing to take them on to the extent that manufacturing efforts can be greatly scaled up.

The International Flow Battery Forum is taking place this week and long-time organiser, Anthony Price of consultancy Swanbarton, wrote to Energy-Storage.news with some of his views on the market and a snapshot of where development currently lies.
