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.
