Redflow shows off commercial “QuadPod” battery, ahead of installation

Australian long duration energy storage company Redflow has showcased its commercial-scale battery solution, the Quadpod, as it prepares to install one of the units for electrical engineering company, Fredon.

Integrated with a Deye hybrid inverter, Redflow’s Quadpod is offers up to 40kWh of storage in a plug-and-play, pre-wired version of the company’s zinc-bromine flow battery.

The Australian designed flow batteries, while currently more costly than their lithium-ion counterparts, offer longer duration storage using a chemistry that is sustainable, fire-resistant, operable in extremes of temperature and capable of 100% depth of discharge.

After a slow and sometimes shaky start in its home market, Redflow has been making significant progress overseas, particularly in the US where the Biden Administration’s IRA policy is driving investment in alternative battery technologies.

In the US, multi-megawatt-hour scale projects have been the most popular – including a 20MWh energy storage system approved for use in a US microgrid project in California, to go with 5MW of solar.

In Australia, Redflow might be hoping its commercial and industrial solution might have better success.

In a post on LinkedIn on Tuesday, Redflow shared a glimpse a Quadpod in action, at a training session for Fredon ahead of the installation of their Quadpod this month.

“Capable of delivering 40kWh of energy at up to 12kW from an integrated Deye Inverter, the QuadPod features 4 ZBM batteries, pre-wired and installed in a custom designed enclosure,” the post says.
