Electric vehicle (EV) adoption is accelerating globally and with it, a new wave of opportunity. EV batteries are typically replaced once they lose 20–30% of their original capacity, but at that point they still retain productive potential. Instead of becoming waste, these batteries can be repurposed for a “second life” in less demanding applications, including microgrids powering communities, charging infrastructure, electric two- and three-wheelers and grid support services. 

The scale of this opportunity is rapidly approaching. The volume of retired EV batteries is projected to exceed 300 GWh by 2030, with at least half originating from China alone. An estimated 40–70% of these batteries could be suitable for second-life applications, representing a vast reserve of energy storage capacity ready to be deployed. If effectively harnessed, second-life batteries could improve energy access, lower system costs, support grid resilience, and accelerate the clean energy transition. 

However, the pathway forward is far from straightforward. While early projects demonstrate technical feasibility, scaling second-life solutions raises complex questions around performance standards, safety, economic viability, ownership models, and end-of-life responsibility. Market forces alone are unlikely to deliver optimal outcomes at the pace required. Without clear frameworks, the sector risks fragmentation, underinvestment, or unintended environmental and social impacts. 

This webinar will explore how stakeholders across government, industry and civil society can work together to unlock the full value of second-life batteries while managing risks. It will highlight priority areas where greater clarity, coordination, and ambition are urgently needed and begin to outline what a credible, forward-looking game plan could look like.
