vanadium redox flow

US researchers have facilitated the decoupling of power from energy design by incorporating a conducting carbon slurry in the negative electrolyte of an all-iron flow battery. In a new study, they describe the design considerations for slurry iron redox flow battery scalability.

The US Department of Energy’s Pacific Northwest National Laboratory has made a third semi-exclusive commercial license for vanadium redox flow battery technologies, in order to help bring the technology to market.

Norwegian consultancy DNV today published the latest of its annual surveys of the state of the energy transition and lamented the fact so very little has been achieved during the last five years. We are forging ahead into a world that will be 2.3C hotter this century, predicts the report.

The Australian government has recognized TNG’s flagship Mount Peake Project – a mine that includes production plans for vanadium redox flow batteries and green hydrogen – as nationally significant.

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.

Spanish storage specialist E22 said its new system can be integrated within a modular block from 250 kW to 330 kW. It purportedly has a product life above 12,000 cycles at full power.

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.

A new research paper looks at the membranes used for applications in vanadium redox flow batteries. It outlines various membrane technologies and the obstacles to bringing batteries to mass production.
