Flow battery companies Redflow and Invinity Energy Systems are targeting the US market through partnerships with third parties.

Australia-based zinc-bromine flow battery company Redflow, which has a market cap of nearly US$60 million, has halted stock market trading as it prepares a capital raise.

Redflow has reported a significant rise in revenues from its zinc-bromide flow batteries but the Australian company noted that it expects to remain “cash-flow negative for some time”.

CellCube has agreed a five-year, three-million litre/year bulk electrolyte supply deal with producer US Vanadium.

Redflow’s zinc-bromine based devices have been picked by the New Zealand Rural Connectivity Group to help extend mobile coverage and internet connectivity to thousands of homes and businesses in remote areas.

Australia-headquartered flow battery maker Redflow is continuing with a strategy of selling devices into the telecoms sector, agreeing on a second deal to repower mobile phone towers for a South African provider.

Following announcements from various manufacturers of deployments and partnerships in new territories, the latest wave of flow battery news includes an agreement that could put batteries in space for mission critical applications at the likes of NASA and the International Space Station.

While energy storage, like the electrification of transport, is often discussed as the ‘Next Big Thing’ for first world economies, this emerging technology is starting to play an important role in developing nations too.

Redflow will provide 32 of its zinc-bromine flow batteries to two new children’s centres in its native Australia.
