Episode 23: The Future of Energy Storage | Electrostatic Graphene vs. Lithium Batteries

In this episode of The Clean Energy Edge, Russ Bates and Brian Scott sit down with Stephanie Choi Brookes, Chief Marketing Officer at Emtel Energy USA, to explore a breakthrough in long-duration energy storage. Stephanie explains how Electrostatic Graphene Energy Storage (ELDES) is disrupting the market by eliminating the fire risks and degradation issues tied to lithium-ion batteries. She shares insights from her journey into clean energy, why storage is the “linchpin” of the renewable transition, and how Emtel is scaling projects from telecom to utility-scale. Topics covered include: Why lithium-ion batteries fall short on safety, longevity, and true cost. How electrostatic graphene storage works (plain English version). Real-world deployments from the Alps to Abu Dhabi. Upcoming U.S. pilots, including Duke Energy’s microgrid project. Economic case: 100% depth of discharge, 500k+ cycles, 25-year predictable life. Sustainability advantage: graphene sourced from waste, recyclable and biodegradable. Residential solutions competing with Tesla Powerwall, with far greater throughput. If you want to understand where storage is headed — and why electrostatic long-duration energy storage could reshape the grid, data centers, and our homes — this is a conversation you don’t want to miss. 👉 Don’t forget to subscribe and hit the alert bell for more straight talk on energy policy, technology, and the future of clean power.
