In this episode of the Energy Technology Podcast, we talk with Manas Patak, CEO and co-founder of EarthEn, about the company’s thermo-mechanical energy storage technology built around supercritical CO₂. Manas explains how this compact, safe, and cost-effective approach enables long-duration energy storage, how it compares to traditional compressed air systems, and why using CO₂ unlocks new performance advantages. We also discuss EarthEn’s ability to turn existing pipelines into energy storage assets, the wide range of customers they’re targeting, their funding journey through DOE grants, and the path toward launching their first commercial product in 2026–2027 as they work to expand access to clean energy worldwide.
