General Motors and Redwood Materials are joining forces to take EV battery tech beyond the road and onto the grid. The two companies just signed a non-binding memorandum of understanding that sets the stage for turning both new and second-life GM batteries into energy storage systems to support the US’s rising electricity demand.
The collaboration aims to help the grid keep up with the surge in power-hungry applications, from AI data centers to electrified transport and industry.
“The market for grid-scale batteries and backup power isn’t just expanding, it’s becoming essential infrastructure,” said Kurt Kelty, GM’s VP of batteries, propulsion, and sustainability. “Electricity demand is climbing, and it’s only going to accelerate… GM batteries can play an integral role.”
Redwood launched a new venture in June called Redwood Energy that repurposes both new and used EV battery packs into fast and cost-effective energy storage systems. Today’s announcement allows Redwood to use second-life batteries from GM EVs and new GM battery modules to create US-built energy storage systems.
This isn’t just a future plan – it’s already happening. GM’s repurposed EV batteries are currently powering the biggest second-life battery project in the world. Located in Sparks, Nevada, Redwood’s 12MW/63MWh installation is also the largest microgrid in North America and supports Crusoe, an AI infrastructure company.
“Electricity demand is accelerating at an unprecedented pace,” said JB Straubel, Redwood’s founder and CEO. “Both GM’s second-life EV batteries and new batteries can be deployed in Redwood’s energy storage systems, delivering fast, flexible power solutions.”
And the timing couldn’t be better. AI data centers alone are expected to triple their share of US electricity use, from 4.4% in 2023 to 12% by 2028. That’s driving the urgent need for scalable, domestic energy storage.
GM and Redwood Materials say they’ll share more details on their plans later this year.
