Over the last two months, a first-of-a-kind project has taken shape at an industrial site in Nevada: the world’s largest microgrid built with used EV batteries, designed to power an adjacent data center.
It’s the first of a series of microgrids planned by Redwood Materials, the battery recycling company now valued at more than $5 billion. The company is taking in a quickly-growing volume of used EV batteries—tens of thousands over the last year, and perhaps hundreds of thousands over the next 12 months. Most of those batteries still have enough capacity to have a second life before the materials are recycled. And they could help deal with a major energy challenge: how new data centers can come online quickly and cheaply without straining the grid and significantly adding to climate emissions.
