Allegro Energy: Safe, sustainable energy storage for a renewable future

Battery storage startup Allegro Energy is on a mission to make energy storage safer, cheaper and more sustainable. Unlike conventional alternatives, Allegro’s technology doesn’t rely on scarce resources or complex supply chains — and its materials are fully recyclable.

At the heart of their technology is a breakthrough water-based electrolyte, stemming from research at Te Herenga Waka—Victoria University of Wellington. This enables them to produce redox-flow batteries and supercapacitors that are non-flammable, sustainable and more affordable than competing technologies.

With applications ranging from long-duration storage for energy providers to fast-charging for EVs, e-buses and light rail, the potential impact is huge. Now based in Australia, Allegro is scaling production with government and investor backing to help drive the transition to clean energy.
