How to resolve AdBlock issue? Allegro’s ‘next-gen’ energy storage tech secures US patent
HUNTER VALLEY New South Wales-based Allegro Energy has been granted a US patent for its cutting-edge micro-emulsion electrolyte technology, further solidifying its position as a global leader in long-duration energy storage.
This US milestone follows previous patent successes in Europe and several other key markets, showcasing the international significance of Allegro’s breakthrough approach, according to Allegro Energy CEO and co-founder Thomas Nann. 
“The US patent reinforces Allegro’s ability to deliver a truly global and transformative solution for long-duration energy storage,” Dr Nann said. 
“With energy storage playing a crucial role in the renewable transition, our micro-emulsion platform ensures scalability and adaptability across a range of battery chemistries, from redox flow to advanced ion batteries.”
Allegro’s modular micro-emulsion electrolyte system is a game-changer for the energy storage industry, enabling safer, more cost-effective, and scalable solutions for applications ranging from grid storage to renewable energy integration.
By overcoming key limitations of traditional aqueous and non-aqueous electrolytes, Allegro’s technology significantly expands the electrochemical stability window, enhancing energy density while maintaining the affordability and safety of water-based systems.
The key advantage of Allegro’s micro-emulsion technology is its ability to dissolve a wider range of electrochemically active species, while maintaining stability at high voltages – previously a major barrier to the adoption of aqueous electrolytes in advanced energy storage. The solution is applicable to multiple battery formats, including lithium-ion, sodium-ion, magnesium-ion, and aluminium-ion batteries, as well as supercapacitors and redox flow batteries.
With this latest US patent covering all of Allegro’s intended claims, Dr Nann said Allegro Energy was well-positioned to partner with utilities, industrial operators, and battery manufacturers worldwide to drive the future of clean energy storage, and rapidly support the drive to 24/7 carbon-free energy.
Allegro Energy’s water-based electrolyte technology enables energy storage that is not only non-flammable but much less expensive and much safer than competing technology, opening up the ability to address needs at global scale, according to Dr Nann.
“We’re also not reliant on scarce raw materials that are difficult to source or supply chains that are subject to geo-political power-games,” Dr Nann said.
