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”.

A consortium of developers has achieved financial close for US$1.3bn in debt facilities for the Red Sea project, a huge resort under construction off the coast of Saudi Arabia which plans to have the largest off-grid battery energy storage system at 1,200-1,300MWh.

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

Eos Energy Enterprises’ leadership has claimed gross positive margins can be achieved in a year and a half. 

ron flow battery provider ESS Inc has revealed a US$477 million net loss in 2021, in its first full-year results since becoming a publicly-traded company on the New York Stock Exchange (NYSE). 

Stem Inc has offered full-year 2022 revenue guidance of between US$350 million and US$425 million. 

Eos Energy Enterprises has said that equipment and machinery will begin arriving next month as the zinc-based battery storage company expands its manufacturing facility near Pittsburgh.

Pandemic-related supply chain issues for lithium battery materials hitting the energy storage space are just “bumps in the road” for the sector, and the supply chain will “come out stronger because of it”.

Standalone storage, demand from commercial and industrial (C&I) customers and new types of grid services will increasingly help drive growth in energy storage in the coming years, but the future mix between battery-based and alternative storage types is still unclear.

The energy transition arm of Italy’s Enel Group has started construction on a 20MW/40MWh behind-the-meter battery energy storage system at Imperial Oil’s petrochemical complex in Sarnia, Ontario, which it claims will be the largest in North America.
