## About

Based in New South Wales, Australia, and founded in 2021, Allegro Energy Pty Ltd, a.k.a. Allegro Energy operates as an energy storage company that focuses on developing supercapacitors and water-based redox flow batteries that use microemulsion electrolytes. In February 2025, Allegro Energy Pty Ltd received USD 1.85 million of grant funding from new investor Department of Industry, Science and Resources. As of September 2025, Thomas Nann is the CEO of the company. Allegro Energy offers two core energy storage technologies: redox flow batteries and supercapacitors. Redox flow batteries provide long-duration, large-scale energy storage for commercial, industrial, and utility applications. These batteries use water-based electrolytes, making them sustainable, and safe for extended energy storage needs. Supercapacitors, on the other hand, deliver short-term, high-power energy storage, suitable for rapid energy delivery and power applications. Both technologies can be customized and used together or separately to meet various energy goals. The company plans to use its proceeds from September 2024 funding to accelerate its manufacturing capacity.
