Spanish and Finnish scientists have developed a solar vanadium redox flow battery paired with commercially available CIGS solar panels. The open-circuit voltage values were high enough to achieve unbiased photocharge, they said.
A unit of Largo Resources is launching a new vanadium redox flow battery for utility-scale storage projects, microgrids, renewable energy integration, grid smoothing, and backup power. The battery will feature a modular architecture, based on 1 MW “building blocks” and 2 MWh blocks of storage capacity.
Australia’s first utility-scale vanadium flow battery will be built in South Australia. It will demonstrate the tech’s potential to provide energy and frequency control ancillary services for the national grid.
Spanish renewable energy company Abengoa will deploy a 3.5 MW solar micro-grid at a vanadium mining site operated by Bushveld Minerals in South Africa. The storage system will be provided by Austria-based storage specialist Enerox Holdings Limited.
Researchers in India have developed a 5 kW/25 kWh vanadium redox flow battery with an energy density of 30 watt-hours to 40 watt-hours per liter.
