How Battery Recycling Meets AI’s Power Demand: Inside Redwood’s $6B Energy Pivot

From EV Batteries to AI Power Grids: Redwood’s Strategic Evolution

In a move that bridges sustainable technology with artificial intelligence infrastructure, Redwood Materials has secured $350 million in new funding, catapulting the battery recycling pioneer to a $6 billion valuation. The investment round, led by Eclipse with strategic participation from Nvidia’s venture arm NVentures, signals a significant shift in how tech giants are addressing the energy constraints threatening AI’s rapid expansion.

The AI Power Crisis: Why Energy Storage Became Critical

As artificial intelligence deployments multiply across the United States, data centers are consuming electricity at unprecedented rates. The very GPUs that power generative AI and large language models require massive, consistent energy supplies—creating what industry experts now call the defining bottleneck of the AI revolution. Traditional power grids, designed for gradual demand increases, are struggling to accommodate the sudden surge from AI facilities.

Redwood’s solution emerges from an unexpected direction: repurposing used electric vehicle batteries into sophisticated energy storage systems. Through their newly launched Redwood Energy division, the company is transforming discarded power sources into grid-scale batteries that store electricity during low-demand periods and release it when AI data centers need it most.

Strategic Investors Recognize Converging Opportunities

The funding round represents more than just financial backing—it’s a strategic alignment of complementary technologies. Nvidia’s involvement through NVentures demonstrates how the chip manufacturer is thinking beyond silicon to ensure the entire AI ecosystem remains powered. Eclipse’s Joe Fath, who previously backed Tesla during its early growth phase, recognized the potential in Redwood’s expanded vision., as as previously reported

“This energy business is a really exciting opportunity for them to go attack,” Fath explained in an interview. “They have a unique opportunity to build out battery energy storage solutions and leverage all kinds of power generation, whether it be solar, wind, industrial gas turbines and ultimately nuclear, to power data centers that are off grid.”

Three-Pronged Business Model Creates Competitive Advantage

Redwood’s strategy combines multiple revenue streams that reinforce each other:, according to technological advances

• Battery Recycling Foundation: The original business launched in 2017 focuses on reclaiming valuable metals like cobalt, nickel, and lithium from used EV batteries
• Materials Manufacturing: Recent expansion into Cathode Active Material production creates higher-value products from recycled materials
• Energy Storage Systems: The newest division addresses immediate market needs by deploying large-scale battery installations for AI infrastructure

According to Fath, this layered approach allows Redwood to balance long-term investments in materials science with quicker-revenue energy projects. While cathode manufacturing requires substantial upfront capital with longer payback periods, the energy storage business generates revenue almost immediately upon deployment.

Accelerated Timeline Meets Urgent Market Need

The speed of Redwood’s pivot from concept to implementation demonstrates both market readiness and execution capability. After initially presenting the energy business concept to investors in August 2024, the company went live with AI data center provider Crusoe by June 2025—less than a year later.

“Time to market is extremely quick,” Fath noted. “They have a very strong and proven ability to scale.”

This rapid deployment capability positions Redwood to capture market share as AI companies scramble for reliable power solutions. With foreign supply chains becoming increasingly uncertain and renewable energy sources facing intermittency challenges, domestically produced storage systems offer both strategic and practical advantages.

National Security and Technological Sovereignty

Beyond commercial implications, Redwood’s approach addresses fundamental concerns about American energy independence and technological competitiveness. By recycling critical minerals domestically and integrating them into advanced energy systems, the company supports two national priorities simultaneously.

“We need to have energy independence and protect sovereignty in the US,” Fath emphasized. “So it plays into their strengths.”

The company’s sophisticated power electronics and software systems are designed to complement existing energy infrastructure, including natural gas plants and future nuclear facilities. This integration approach maximizes grid efficiency while enabling faster AI deployment without overwhelming local power networks.

Future Vision: Integrated Energy Management

Looking ahead, Redwood plans to expand beyond standalone storage solutions toward comprehensive energy management platforms. The company anticipates developing systems that help customers coordinate energy production, storage, and consumption more efficiently—creating optimized ecosystems for power-intensive applications like AI training and inference.

With fresh capital from the latest funding round, Redwood intends to accelerate its refining capabilities, materials production, and storage deployments while recruiting engineering talent to “shape the next era of American energy leadership and critical minerals independence.” The convergence of battery technology, recycling expertise, and energy management creates a unique position at the intersection of sustainability and technological progress.

As AI continues its exponential growth, the companies providing its power infrastructure may prove as strategically important as those developing the algorithms themselves. Redwood’s evolution from battery recycler to energy enabler demonstrates how solving fundamental constraints can create massive value in rapidly expanding technological ecosystems.
