Turning Retired EV Batteries Into Grid-Scale Energy Storage

What happens to electric vehicle batteries when they’re no longer fit for the road — and how close are we to scaling energy storage without making new batteries at all?

Paula Runsten, Co-Founder and CEO of Rebaba explains how they are giving EV batteries a second life through a battery-agnostic platform that works across more than 40 models, turning retired batteries into safe, grid-scale energy storage.

The discussion explores circular hubs, battery safety and reliability, AI-driven energy management and why second-life batteries can already compete on price while delivering zero-carbon storage and European-controlled infrastructure. A practical, forward-looking conversation on how circular innovation is reshaping the future of energy.
