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.
