Redwood Materials

Securing U.S. critical minerals. Powering America’s energy future.

[Redwood Materials @RedwoodMat]

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.

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.

[Redwood Materials @RedwoodMat]

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.

@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."

Former long-time Tesla CFO Deepak Ahuja joins JB Straubel's Redwood Materials https://t.co/QHyPqtVBSK by @fredlambert

[Redwood Materials @RedwoodMat]

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.

"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.

Redwood Materials founder and CEO JB Straubel transformed what batteries could do at Tesla. Now he's doing it again, changing the way data centers—and the entire energy grid—are powered. https://t.co/JRP4cx6qa6

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.

“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.

[The Wall Street Journal @WSJ]

Exclusive: Rivian is joining with Redwood Materials to reuse EV batteries for energy storage. https://t.co/uv9XB0IEmS

[Redwood Materials @RedwoodMat]

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.

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. 

https://t.co/IZ6BK14xPn

[Redwood Materials @RedwoodMat]

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).

https://t.co/ttG9cTrHNc

[Redwood Materials @RedwoodMat]

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.

@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)

[Redwood Materials @RedwoodMat]

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).

[Redwood Materials @RedwoodMat]

Last year, we deployed a 12 MW/63 MWh microgrid - the world’s largest second-life battery system - to power @CrusoeAI. Since then, it’s delivered 99.2% uptime.

Now, we’re scaling from 4 to 24 Crusoe modular data centers; nearly 7x the original compute capacity. A new model for AI infrastructure: faster to deploy, more flexible, and built on low-cost, reliable energy.

@TommieTurner128 Northern Nevada, just outside Reno

[Redwood Materials @RedwoodMat]

Last week, we unveiled Redwood Energy: our new business that repurposes EV battery packs into low-cost, fast, and scalable energy storage.

We just built a 12 MW and 63 MWh microgrid — the largest second-life battery deployment in the world and the largest microgrid in North America, powering a data center for @CrusoeAI.

The system demonstrates exactly what Redwood Energy is designed to do: bring resilient, low-cost power to market, fast.

[Redwood Materials @RedwoodMat]

In most battery recycling programs, the consumer, retailer, or local government pays a fee because aggregation, logistics, and safe handling for small devices are expensive. We believe recycling should be free to the public, so through our partnerships we provide the Battery Bins and logistics to safely collect and recycle these batteries. We’re investing to build the infrastructure to make battery recycling easier and safer in more communities.

[Redwood Materials @RedwoodMat]

Nevada, we’ve got a new place for your old batteries. Redwood's Battery Bin program has landed in Reno, with ~20 locations coming statewide. Thanks to our partners @WashoeCounty and @NevadaTechHub for helping strengthen the battery supply chain right here in NV. https://t.co/L2Ohh6xdRx
