The Battery Boom: Why Grid Storage Is the Backbone of Clean Power! | The Fully Charged Show Podcast

Battery storage is booming — but how does it really work, and why does it matter?
In this episode of the Fully Charged Show Podcast, Imogen sits down with Ed Porter from ⁨@modoenergy⁩ one of the UK's leading experts on battery energy storage systems (BESS), to demystify the critical role batteries are already playing in balancing the grid — and what’s still to come. From frequency regulation and price arbitrage to blackouts and the path to clean power by 2030, we explore how grid-scale batteries are transforming our energy system faster than you think. Ed shares his insights on:

• Why batteries are replacing gas in grid services — and slashing costs.
• What dynamic frequency response actually means
• How the UK went from 0 to 5.3 GW of battery storage — and where we go from here
• Why the “1.5-hour” battery duration isn't a limitation, but a smart design choice
• How we plan to survive “Dunkelflaute” and keep the lights on in winter.
