How One Startup Is Making Lithium From Geothermal Brine -...

What this episode covers

Episode 59 of The Climate Tech Podcast explores a new frontier in critical mineral extraction: direct lithium extraction from geothermal brine. Lucas and Luna dive into how one startup is using advanced filtration technology to pull lithium — the key ingredient in EV and grid batteries — from hot, mineral-rich water deep underground. They discuss the specific chemistry, the energy economics, and why this approach avoids the environmental headaches of traditional hard-rock mining and evaporation ponds. The episode also touches on the scale challenge: can this process move from pilot plants to supplying millions of battery-grade tons per year? With lithium demand projected to grow sixfold by 2030, this technology could reshape supply chains and decarbonize an otherwise dirty industry. #Lithium #Geothermal #DirectLithiumExtraction #BatterySupplyChain #CriticalMinerals #CleanTech #ClimateTech #EVBatteries #GridStorage #Startup #DeepUnderground #FiltrationTechnology #Sustainability #Decarbonization #EnergyTransition #Business #Technology #FexingoBusiness Keep every episode free: buymeacoffee.com/fexingo
