Who is Redflow?


About us 

Redflow is leading the renewable energy transition by delivering one of the world’s safest and cleanest energy storage solutions.

Our battery is the world’s smallest and most scalable, commercially available, zinc-bromine flow battery. We are proud to produce one of the most environmentally friendly energy storage solutions in the world, our batteries are fully recyclable and manufactured from widely available, low-toxicity materials. Our energy storage technology is scalable, from tens of kilowatt hours to hundreds of megawatt hours to suit your energy storage needs. The batteries are ideally suited for extreme conditions and can operate without additional cooling or heating and with no degradation from 10 degrees Celsius to 45 degrees Celsius (59 degrees Fahrenheit to 113 degrees Fahrenheit).

Redflow proudly developed our technology in Australia, and we have the capability to deliver it globally. Our deployments are located throughout the world, so we can meet your energy storage needs. Redflow is dedicated to a sustainable, carbon-free future, and we are proud that our flow battery technology will help to build the energy storage systems of today, as well as tomorrow.


Our history

Redflow was founded in 2005 when brothers Chris and Alex Winter identified an opportunity in re-dox flow battery technology. During the next few years, they developed the technology and delivered a prototype.

Redflow has grown since then, evolving from an R&D company to a globally focussed leader in safe, clean and sustainable energy storage technology.

Energy storage has come a long way during the past 10 years, with flow battery solutions now recognised as having an essential role to play in the global move to net zero emissions.

We are proud to be one of the world’s longest running flow battery energy storage companies, with decades of design and operational experience that equips us with the knowhow to continue growing and meet the world’s future energy storage needs.
