Retired EV batteries keep 70–80% capacity for grid storage

EV batteries retired from cars typically retain 70–80% of their original capacity, making them suitable for grid stabilization and renewable energy storage instead of immediate recycling. Projects by B2U Storage Solutions and Moment Energy in California and Canada show the approach works, but high testing costs and cheap new batteries limit adoption.

• Retired EV batteries retain 70–80% of original capacity
• B2U and Moment Energy already run second-life grid projects
• High repurposing costs and cheap new batteries hinder scaling
• EVs projected at 30% of global new car sales by 2026
