A vanadium redox flow battery (VRFB) with a 24-hour discharge duration will be built and tested in a project launched by Pacific Northwest National Laboratory (PNNL) and VRFB technology provider Invinity Energy Systems.

Europe-based organic flow battery company CMBlu has won its second US project, a 5MW, 10-hour duration pilot system with Arizona utility Salt River Project (SRP).

Rules on battery sustainability, performance and labelling will become more stringent within the European Union (EU).

Lithium-ion will struggle to compete at long durations and its price declines cannot continue forever, said Alan Greenshields, Director EMEA for iron electrolyte flow battery supplier ESS Inc, in a rebuttal to an earlier Energy-storage.news article on the topic.

Schmid and Saudi companies are also planning a gigawatt-scale manufacturing facility for Vanadium Redox Flow Batteries.

US chemistry firm and redox flow battery company to work together to improve competitiveness of the energy storage technology.

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

First developed by NASA, flow batteries are a potential answer to storing solar – and wind – for eight to 10 hours, far beyond what is commonly achieved today with lithium-ion. In the second of a two-part special report, Andy Colthorpe dives deeper into questions of bankability, market segmentation and manufacturing strategies with four very different providers of flow energy storage technology.

Some of the “world’s biggest insurance companies” are investigating the advantages of pairing lithium batteries with ultracapacitors in energy storage systems, which can lower costs and extend battery lifetimes, the CEO of an ultracapacitor maker has said.
