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”.

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.

India-based promoter of decentralised power Clean Energy Access Network (CLEAN) has issued a request for proposal (RfP) for lithium-ion technology providers to show how their solutions can aid mini grid and distributed renewable energy development in India.

At least two global technology leaders could set up Gigafactories to manufacture lithium-ion cells in India in the next couple of years, and most major Indian firms are setting up energy storage divisions, according to the head of the India Energy Storage Alliance (IESA).

Orders for distributed energy storage and the rise of an electric mobility market have kick-started a battery assembly push in India.

ABB has signed a memorandum of understanding (MoU) with Chennai-based engineering and research organisation, the Indian Institute of Technology Madras (IITM) to partner on building microgrids and develop R&D in the battery energy storage area.

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”.
