Allegro Energy

Startup

Allegro Energy makes electrical energy storage safe, efficient, sustainable and affordable. Whether in electric mobility, medium to large-scale energy storage or uninterrupted power supply, Allegro's proprietary technology brings us one step closer to a zero carbon economy. 

Allegro Energy is a Newcastle-based battery energy storage startup manufacturing water-based, non-flammable redox flow battery systems (RFBS) for long-duration energy storage applications across Australia. Our technology is purpose-built for the 8-24h+ discharge window that the market urgently needs — providing overnight grid firming for renewable energy developers, network operators, utilities, and industrial energy users including mining and data centres.Allegro's water-based electrolyte chemistry is inherently non-flammable and non-toxic, eliminating the fire risk that restricts conventional battery storage in remote, densely populated and environmentally sensitive locations. Our systems are locally manufactured, supporting Australian energy sovereignty and supply chain resilience. Allegro is currently progressing a utility-scale pilot with Origin Energy at Eraring, marking a significant milestone in the commercialisation of long-duration storage in Australia.
