Allegro Energy’s core technology is its proprietary Microemulsion Flow Battery (MeFB) technology using a water-based microemulsion electrolyte. This safe, non-flammable, and recyclable technology avoids rare earth elements and hazardous substances. The MeFB supports long-duration energy storage from 4 to over 24 hours, outperforming conventional lithium-ion batteries. The platform is versatile, compatible with chemistries like lithium-ion, sodium-ion, magnesium-ion, aluminum-ion, and supercapacitors, designed for utility scale with durability and ease of maintenance.
Allegro Energy offers microemulsion flow batteries optimized for long-duration energy storage with continuous energy supply capability for 4 to 24+ hours. They also develop water-electrolyte supercapacitors for rapid charge-discharge applications requiring short bursts of power while maintaining safety and recyclability. Key product deployment includes a 100 kW/800 kWh MeFB system designed for 8 hours continuous dispatch.
Key projects include Australia’s first domestically manufactured microemulsion flow battery installed at Eraring Power Station (100 kW/800 kWh) in partnership with Origin Energy, serving as a demonstration before scaling up. The company received Australian government grants and holds a US patent (2024) for its microemulsion electrolyte. The project supports utility scale renewable integration and data center power backup applications.
Allegro Energy completed a AU$17.5M Series A funding round in 2024, led by The Grantham Foundation. Other investors include Origin Energy (5.0% equity stake and collaborative pilot projects), Lightbank, Melt Ventures, and Impact Ventures. The company also received AU$4M in federal and state government grants for technology R&D and manufacturing expansion.
