Redwood Materials

The solution to America’s growing energy demand might already be on our roads. As millions of EV batteries retire from vehicles, many still have years of useful life left. Redwood Energy redeploys them as grid-scale storage today, powering data centers and strengthening the grid, before we recover their critical minerals at end-of-life.

Building a domestic battery supply chain means working across the entire lifecycle. From automakers to gigafactories to large-scale energy storage, Redwood's partner network spans every stage: recovering end-of-life batteries, supplying domestically produced materials for new cell manufacturing, and deploying grid-scale storage for data-center applications. Securing critical materials. Strengthening energy dominance. Powering the next era of American industry

The future of energy isn't just about making new things, it's about getting more out of what we've already built. Redwood's Chief Commercial officer, Cal Lankton sat down with @live_munro and @arocha_jordan to talk second-life batteries, grid resilience, and 7.2 MWh of repurposed @GM packs in action.

Thanks for stopping by our Tahoe campus and diving into the details of how we’re building a true battery ecosystem! We're leading the nation in critical battery material recovery and also building the largest microgrids in North America out of repurposed batteries! If you like "nerding" out on stuff like this, we are growing our San Francisco and Tahoe campus!

Colorado’s EV battery recycling bill was signed into law, establishing the most comprehensive EV battery management framework in the U.S. At Redwood, we know that end-of-life EV batteries are not waste. They are valuable assets, whether for energy storage or critical mineral recovery. The framework prioritizes repurposing before recycling, supporting domestic energy storage deployment and extending the productive life of these assets. It establishes a clear recycler standard requiring actual extraction, separation, or refining of materials. It sets strong recovery standards with appropriate phase-in timelines, takes an outcome-based approach rather than banning specific technologies, and preserves direct manufacturer-recycler relationships rather than routing through a centralized stewardship organization designed for negative-value waste products. Redwood works across the full battery lifecycle, from second-life energy storage tomaterial recovery, and we've been working on end-of-life policy diligently.. As other states take up this topic, we're ready to be a resource for the partners and policymakers working to get this right.

“I think we should be really worried.” @Tesla cofounder and CEO of @RedwoodMat JB Straubel warned at #BrainstormTech that China's pace of infrastructure development is moving at a scale and speed that's difficult for many Americans to grasp. bit.ly/4xkvVyY

Today, we're announcing the latest chapter of our partnership with @GM. Redwood will deploy 1.5 MW / 7.2 MWh of dispatchable energy storage at a GM manufacturing facility in Michigan, built from ~100 repurposed GM battery packs. The U.S. holds a massive and growing stockpile of domestic battery assets. The question is whether those batteries stay here as American energy infrastructure or whether that value leaves the country. With this deployment, GM and Redwood are proving it can stay here. This makes GM the first automaker to partner with Redwood across every stage of the battery lifecycle. Redwood already recycles manufacturing scrap from @UltiumCells, GM's battery joint venture with LG Energy Solution, and receives GM EV packs for repurposing or recycling. This deployment puts those same packs back to work on the manufacturing floor. American-made batteries powering American industry, with critical minerals kept in domestic supply chains. The full battery lifecycle managed domestically. From the manufacturing line to the road to the grid. redwoodmaterials.com/news/general-m…

We're in Houston at American Clean Power Conference. @USCleanPower Come find us at booth #3739 to see how Redwood Energy is deploying grid-scale energy storage built from domestic EV batteries.

We'll be in Houston next week at the American Clean Power Conference (ACP). @USCleanPower Redwood Energy builds battery energy storage systems from repurposed EV batteries, turning a domestic resource into reliable, low-cost energy infrastructure. Stop by our booth to learn more, grab an energy drink on us, and catch our VP of Energy Storage, Claire McConnell, on Tuesday, June 2 at 2:30 PM for a discussion on how we’re scaling Redwood Energy.

The entire battery materials supply chain has historically come from outside of the U.S. Redwood is changing that. We're building the first complete domestic circular economy for critical minerals to strengthen American energy security.  inc.com/leah-carroll/1…

@FredLambert We agree! "This is one of those hires that makes perfect sense. Ahuja knows the battery industry’s financial dynamics better than most.. He understands battery economics, manufacturing scale-up costs, and the capital markets appetite for clean energy companies. Redwood needs exactly that right now."

Today, we welcome Deepak Ahuja as Redwood Materials Chief Financial Officer.  Deepak brings decades of financial leadership at companies including Tesla, Verily Life Sciences and Zipline. Energy storage and domestic critical mineral supply have moved from long-term thesis to immediate national priority. Deepak joins at the right moment to help us scale both.  Learn more about Deepak and Redwood here: redwoodmaterials.com/news/welcoming…

"In a moment defined by grid bottlenecks and soaring demand, Redwood is rethinking how energy infrastructure can be built — and reused."   Fast Company spent time with us at Redwood to dig into how we are building domestic energy storage infrastructure from batteries that already exist, at roughly half the cost of new systems, and where this is headed as the wave of end-of-life batteries continues to grow.

We’re honored to be included by @TIME as one of the Top 10 Most Influential Energy Companies of 2026. Energy is one of the most critical challenges to solve in the U.S. today. At Redwood, we’re focused on building the infrastructure needed to support a more reliable and resilient domestic supply chain. From recovering critical materials to deploying energy storage systems, our team is developing & deploying technologies to deliver reliable energy where it’s needed most today and in the future. time.com/article/2026/0…

“These batteries are already built. They don't have to get imported from some other place." @WSJ sits down with @JBStraubel and @RJScaringe on how Redwood is powering part of @Rivian's manufacturing plant using repurposed batteries - the first second-life BESS deployment supporting a U.S. automaker.

We’re partnering with @Rivian to deploy the first Redwood Energy system at a U.S. auto manufacturing plant. 10 MWh of onsite, dispatchable energy, cutting peak costs, reducing grid strain, and powering large-scale manufacturing operations. redwoodmaterials.com/news/rivian-an…

Grid storage that's faster to build (and made in the U.S.), easier to manage, and lower cost. @_LatitudeMedia breaks down how we built Redwood Energy and why "simplicity" is a technical discipline. Go deeper: our white paper covers system architecture and how Redwood Energy stacks up against imported systems.    latitudemedia.com/news/how-redwo…

Energy demand is surging. Storage is the unlock. We’re building a faster, lower-cost solution using batteries already here. Our whitepaper goes deeper: how we decide reuse vs. recycle, system architecture, and how Redwood Energy compares to LFP (90%+ lower carbon emissions). redwoodmaterials.com/resources/unlo…

We tested the Redwood Energy storage system against the toughest new UL fire safety standard - and passed every test. Our technology meets (and exceeds) the highest safety benchmarks. redwoodmaterials.com/news/redwood-s…

@RealJohnShoe @FastCompany We're pretty close! Our operations already represent one of the largest and only new, domestic sources of lithium to come online in decades (and largest cobalt and nickel source, mined or recycled)

@RedwoodMat @FastCompany There will be a time when more useful raw lithium will come from recycling than any other source. It is not this day, but it will come.

A year ago, Redwood Energy hadn't launched. Today, we’re powering high-performance compute with repurposed batteries - and we were just named the #1 energy company on @FastCompany's Most Innovative Companies list (#14 overall). fastcompany.com/91502981/redwo…
