EV batteries usually last longer than the car: Now they are being re-used to power the grid
Rivian and Redwood Materials are partnering to deploy a grid-scale battery using second-life EV batteries, providing 10 MWh of storage at Rivian's Illinois manufacturing plant. This project showcases a scalable model for adding energy capacity using repurposed EV batteries.
US electric car maker Rivian has partnered with Redwood Materials to deploy a grid-scale battery using second-life EV batteries. The initial project will provide 10 megawatt-hours of storage at Rivian's Illinois manufacturing plant. The system is designed to be rapidly scalable and offers cost benefits by utilizing safe and proven EV batteries. JB Straubel, Redwood's founder, notes that EV batteries are often the longest-lived part of a vehicle and can remain healthy even after the vehicle is retired. The partnership is seen as a significant development in the industry, with Morgan Stanley analysts suggesting it could introduce a new revenue stream for EV makers. The project builds on Redwood's existing work with GM second-life batteries, which are being used to power a 12MW/63MWh installation in Nevada.
