Waymo’s spent robotaxi batteries will be used as grid storage

Waymo’s spent robotaxi batteries will be used as grid storage

The company announced a deal with B2U Storage Solutions to repurpose the battery packs as Waymo pulls them off the road.

Why this matters
Why now

The increasing volume of end-of-life EV and robotaxi batteries, combined with growing demand for grid storage solutions, makes repurposing economically viable and environmentally necessary.

Why it’s important

This initiative addresses the sustainability challenge of EV battery waste while simultaneously providing a solution for grid stabilization, critical for integrating renewable energy sources.

What changes

A new, circular economy model for EV batteries begins to scale, reducing waste and contributing to grid resilience without solely relying on new battery production for stationary storage.

Winners
  • · Battery recycling companies
  • · Renewable energy developers
  • · Electric utilities
  • · EV manufacturers (reputational gain, potentially reduced disposal costs)
Losers
  • · New grid-scale battery manufacturers (potentially increased competition)
  • · Landfill operators (reduced battery waste)
Second-order effects
Direct

Repurposed EV batteries provide a cost-effective and environmentally friendly option for grid energy storage.

Second

The economic viability of second-life battery applications accelerates EV adoption by improving their lifecycle sustainability and reducing environmental concerns.

Third

Standardization of EV battery designs and easier modularity may emerge to facilitate more efficient and widespread repurposing and recycling operations globally.
