Polarium, a Sweden-headquartered energy storage system manufacturer, has raised SEK562 million (US$48.3 million).

Finland telecommunications firm Elisa has received €3.9 million from the government to form a VPP using batteries which could be the largest of its kind in Europe.

Caban Systems, a US battery tech company offering renewable energy solutions to critical infrastructure industries, has raised US$51 million.

Polarium, a Swedish manufacturer of lithium-ion based battery energy storage systems (BESS) technology, has been valued at over a billion dollars.

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”.

News in brief from around the world in energy storage.

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.

Redox flow energy storage systems, earmarked by Navigant Research to be one of the fastest growing electrochemical storage technology sets over the next decade, are being deployed in recent or upcoming projects by Cellcube Energy Storage Systems and Redflow.
