Redwood Materials EV battery microgrids offer low-cost energy solutions
Redwood Materials is giving electric vehicle batteries a second life—by transforming them into energy storage systems that power homes, businesses, and data centers. These Redwood Materials EV battery microgrids use still-functional lithium-ion batteries from retired EVs, offering a cheaper alternative to brand-new storage units. As demand for sustainable and affordable energy grows, this innovation is drawing attention for its cost savings and grid resilience benefits. Founded by former Tesla executive JB Straubel, Redwood’s new initiative, called Redwood Energy, is scaling rapidly.
How Redwood Materials repurposes EV batteries into microgrids
Instead of immediately recycling batteries, Redwood Materials evaluates each one for remaining life—many still hold up to 50% capacity. If a battery is still functional, it’s placed into a modular system designed for grid storage. These storage units are flexible, allowing them to operate independently or connect to larger networks. The company receives over 20 GWh of batteries annually, equivalent to around 250,000 vehicles, and claims over a gigawatt-hour of reusable energy in its pipeline, with projections of 5 GWh more by next year. This approach reduces electronic waste and supports a more circular battery economy.
Real-world example of Redwood’s battery-powered microgrid
Redwood has already launched a microgrid using its upcycled battery tech at its Nevada campus. This installation powers a modular AI data center operated by Crusoe, delivering 12 MW of power and 63 MWh of capacity. The company touts it as the largest second-life battery deployment in the world—capable of powering 9,000 homes or charging an EV for a journey to the moon and back. This milestone proves how Redwood Materials EV battery microgrids can support both clean energy goals and AI infrastructure needs at scale.
Redwood’s wider role in EV battery recycling and clean tech
Since 2017, Redwood Materials has partnered with companies like Tesla, Amazon, Ford, and Toyota to recycle EV and e-bike batteries. Beyond recycling, it now manufactures critical battery parts—anodes and cathodes—at its South Carolina plant. The launch of Redwood Energy signals a broader shift from battery recycling alone to energy storage innovation. As more EVs retire, and battery demand soars, Redwood’s microgrid solution could help stabilize the power grid while cutting emissions and infrastructure costs.
