#163: Can Renewable Energy Replace Combustion? This Company Thinks It Can With FeX Energy

In this episode of Earthlings 2.0, we speak with Hayden Smith, CEO of FeX Energy, about the growing challenge of decarbonizing industrial heat and why long-duration energy storage may become essential to the future of clean manufacturing and grid reliability. While renewable electricity adoption continues to grow, many industrial sectors still rely on fossil fuel combustion to generate the high-temperature heat needed for cement, steel, chemicals, plastics, mining, and food processing. Hayden explains how FeX Energy is developing an iron-based thermal energy storage system capable of storing renewable electricity for long durations and releasing it later as high-temperature industrial heat approaching 900°C. The conversation explores how thermal energy storage could help stabilize renewable-heavy grids, reduce dependence on natural gas, support industrial electrification, and help industries decarbonize without requiring massive transmission infrastructure upgrades.Key Points:Industrial heat remains one of the hardest sectors to decarbonize – Heavy industry still depends heavily on fossil fuel combustion for high-temperature manufacturing processes.FeX Energy uses iron as a long-duration thermal battery – The company’s Iron Arc Reactor stores renewable electricity and releases it later as high-temperature industrial heat.Long-duration energy storage could improve grid flexibility and industrial electrification – Thermal storage systems may help manage renewable intermittency, reduce grid strain, and lower infrastructure upgrade costs.Hayden Smith, CEO of FeX Energy, LinkedInLuis de Leon, Earthlings 2.0 Guest Host, Sr. Public Relations Account Executive at Technica Communications🚀 Calling all Earthlings…  Visit our website for more episodes!Sign up to our newsletter for the latest news on the most exciting technology and research shaping our futures! We want to learn more about you!
