Navigant predicts that by 2035, this market will reach an impressive size of 11 GWh annually.

Initial idea was to use EV batteries for grid energy balancing

New focus on V2G, vehicle-to-home (V2H) and vehicle to building (V2B), UPS, renewable energy

Barriers

12

Economic uncertainty about second-life battery value:

Potential future competition from cheap new energy

storage

Potentially expensive repurposing or redesigning of the

battery pack for new applications

Solution: Reduce uncertainty and costs in the second-life

battery market through demonstration projects and financial and regulatory support.

Complex and adverse regulatory structures:

Solution: policymakers should consider committing to develop clear and consistent regulations over specified time lines.

13

Liability concerns about which entity is responsible for

second-life:

Solution: Industry leaders should identify and replicate

existing liability models for automotive parts for application

to second-life battery liability

Lack of data about battery performance in both first and second life applications:

Solution: Make Electric Vehicle Battery Data Available

Barriers
