Episode description
What if the future of energy storage didn’t rely on lithium? In this episode, Karl speaks with John Wood, CEO of Gelion - an AIM-listed Anglo-Australian battery tech and recycling company leading the charge in the energy transition.
John unpacks Gelion’s Gen 3 sulphur cathode breakthrough, how solid-state batteries could transform EVs and aerospace, and why abundant, low-cost materials like sulphur and zinc are key to the next era of clean tech. We also explore his work with NOAB Ventures and how circular economy thinking is reshaping battery recycling.
🎧 Sulphur just got sexy.
