About Thomas Nann

Thomas Nann is co-founder and chief executive of Allegro Energy, based at Thornton in the Hunter region of New South Wales, which is developing long-duration flow batteries for utility-scale renewable energy storage. Allegro's batteries use a water-based microemulsion electrolyte that the company says is non-flammable, made from abundant materials and fully recyclable, and its first commercial pilot is at Eraring Power Station.

A physical chemist with a PhD from the University of Freiburg, Nann co-founded Allegro in 2021. He previously served as Head of School at the University of Newcastle and as Alan MacDiarmid Professor of Chemistry at Victoria University of Wellington, and is named on international patents in electrolyte and surface chemistry.

On The Mix with Mick Liubinskas, he discussed Allegro's plans for sustainable long-duration batteries.
