Redwood Materials Launches Energy Storage Business, Targeting AI Data Centers with Repurposed EV Batteries

Redwood Materials Enters Energy Storage Market

Redwood Materials, a battery recycling company founded by former Tesla CTO JB Straubel, has announced the launch of Redwood Energy, a new business line focused on repurposing used electric vehicle (EV) batteries for energy storage 1

. This innovative approach aims to address the growing energy demands of AI data centers while providing a sustainable solution for retired EV batteries.

The Microgrid Project: Powering AI Infrastructure

Redwood Energy's first major project is a microgrid located at their facility in Sparks, Nevada. This installation, which is the largest microgrid in North America, consists of 805 retired EV batteries and generates 12 MW of power with 63 MWh of capacity 1

Repurposing EV Batteries: A Sustainable Approach

Redwood Materials recovers more than 70% of all used or discarded battery packs in North America 1

. This approach not only extends the life of the batteries but also provides a cost-effective solution for energy storage.

Addressing the Energy Demands of AI

The repurposed battery systems are particularly well-suited for modern data centers, which are experiencing rapid expansion due to the rise of AI and cloud computing. Analysts forecast that by 2028, data centers could consume up to 12% of all electricity generated in the US 4

. Redwood Energy's microgrids offer a solution to this growing demand while utilizing renewable energy sources.

Future Plans and Market Potential

Redwood Materials has ambitious plans for its energy storage business. By 2028, the company aims to deploy 20 gigawatt-hours of grid-scale storage, positioning itself to become the largest repurposer of used EV battery packs 1

.

Economic and Environmental Benefits

The repurposed battery systems offer significant economic advantages, with Redwood claiming they can be deployed at about half the cost of new lithium-ion systems while providing similar performance 4
