A solar-plus-storage microgrid being deployed at an alloys mine in South Africa will feature a vanadium flow battery energy storage system, using locally sourced vanadium electrolyte.

We caught up with Bo Normark in his capacity as EIT InnoEnergy executive to discuss the past, present and future of energy storage, with his organisation taking the lead in the European Battery Alliance.

A group of Community Choice Aggregators (CCAs) in California, US, are seeking long-duration energy storage to add resiliency to their electricity networks serving around three million customers.

While redesigning California’s energy system will take some time, in the past couple of weeks alone, Energy-Storage.news has become aware of numerous initiatives and projects, both publicly and privately-driven, that are seeking to modernise, add resilience to and lower the emissions of the California grid.

Energy storage systems based around vanadium redox flow batteries (VRFBs) are being developed for residential use in Australia by partners Australian Vanadium (AVL) and Gui Zhou Collect Energy Century Science and Technology.

An agreement to support the manufacture and sale of vanadium flow batteries has been struck between Australian Vanadium and Enerox, which makes and markets systems under its CellCube brand.

Invinity Energy Systems, supplier of a grid-scale vanadium flow battery being installed at a site in the UK will rent the battery’s electrolyte out to the investor developing the project, thereby helping lower the upfront cost of getting the system deployed.

The Energy Superhub Oxford in England is a sophisticated project to create a decarbonised urban environment using a mix of advanced technologies. Jorn Reniers, Postdoctoral Researcher at the University of Oxford’s Department of Engineering Science gives us insights into his role, which is to make a digital twin of the Superhub, including its 50MW hybrid battery storage system.

The new CEO at VRB Energy, a maker of vanadium redox flow battery energy storage devices, claims that ongoing improvements to its technologies will allow it to outcompete lithium-ion energy storage in the coming years.

There’s a race to develop new technologies – and adapt existing ones – that can either be complementary to lithium batteries, or even compete with them. Representatives from three technology providers offer up some case studies, data, insights and opinions on where they think the market could go.
