Meet the innovators: Allegro Energy
Allegro Energy is transforming energy storage with water-based batteries made in the Hunter, exemplifying how locally developed technologies can drive both environmental and economic benefits.
Thornton-based company Allegro Energy is at the forefront of clean energy innovation with a project to develop a low-cost, long-duration battery that uses a water-based electrolyte. This development is being supported by a $2.1 million grant from the NSW Government's Clean Technology Research and Development Grant Program. The grant, part of a $7 million funding round by the NSW Environmental Trust, is one of four awarded to projects aimed at advancing low-emission technologies.
Allegro’s battery project centres on its proprietary Microemulsion Flow technology. This technology offers advantages over existing long-duration energy storage solutions, including improved safety and the ability to store energy for more than 10 hours. Allegro’s batteries are non-flammable, recyclable, and made from abundant materials. Key components will be manufactured locally, addressing the growing demand for renewable energy storage solutions.
With the support of this grant, Allegro is poised to contribute significantly to the energy transition in the Hunter by providing safe, cost-effective, and sustainable energy storage solutions that meet the needs of renewable energy systems across Australia.
“We are grateful for the grant, which enables us to rapidly develop battery manufacturing locally to help deliver a clean energy future for Australia and the rest of the world," Thomas Nann, CEO and co-founder of Allegro Energy said.
"Being located in the Hunter region is a bonus for us because the skills we need are all available in our local community, which is currently grappling with a transition from its traditional industries.”
The NSW Environmental Trust’s program supports research and development projects across a range of clean technologies, including energy systems, primary industries, and power fuels. Allegro’s project was selected from nearly 80 expressions of interest and is part of the state’s broader effort to drive emissions reduction and support innovative approaches to tackling climate change.
Allegro Energy’s advancements extend beyond flow batteries. The company is also developing supercapacitors that can deliver short bursts of high power with fast charging and discharging rates. These supercapacitors, like their batteries, use a water-based electrolyte, making them safer and more efficient to produce.
