Nvidia backs $6 billion battery recycling giant in bid to power the AI boom

Redwood Materials, the battery recycling enterprise founded by Tesla co-founder JB Straubel, has successfully raised $350 million in its latest funding round, elevating its valuation to over $6 billion. This significant investment, spearheaded by Eclipse and supported by Nvidia's venture arm, NVentures, underscores Redwood's emerging role in supporting the booming generative AI sector. At first glance, Redwood's focus on reclaiming metals like cobalt, nickel, and lithium may seem disconnected from the fast-paced world of AI. However, as data centers proliferate across the United States, energy supply has emerged as a critical constraint. Redwood is addressing this challenge through its expanding grid energy storage initiative. In June, the startup launched Redwood Energy, designed to harness repurposed batteries into efficient energy storage systems. These large-scale battery installations provide low-cost electricity, releasing power during peak demand to stabilize the grid and meet the needs of energy-intensive data centers. Joe Fath, who managed the recent funding round and is a former T. Rowe Price fund manager known for early investments in Tesla, highlighted Nvidia's strategic involvement. He noted that this energy venture represents a significant opportunity for Nvidia to explore battery storage solutions integrated with various power generation methods, including solar, wind, and potentially nuclear, to supply off-grid data centers. The energy initiative was first proposed to Fath in August 2024, with Redwood quickly collaborating with AI data center provider Crusoe by June of the following year. Fath praised Redwood's rapid time to market and its impressive capacity for scaling operations. Redwood's evolution has led to improved financial returns with each new business venture. While the initial focus on recycling EV batteries was an essential starting point, the recent shift toward manufacturing Cathode Active Material requires substantial initial investment but is positioned for significant long-term gains. In contrast, Redwood's energy projects generate revenue more swiftly, which Fath believes will pave the way for further innovations in energy management and production. The dual approach of critical materials recycling and energy storage positions Redwood as a crucial player in the modern energy landscape, addressing both energy security and technological competitiveness. With supply chains under pressure and the need for renewable energy sources becoming increasingly urgent, Redwood's domestic storage solutions are poised to enhance grid capacity and expedite AI advancements. With new funding in hand, Redwood plans to expand its refining, materials production, and energy storage efforts, while actively recruiting engineers to lead the next wave of American energy innovation and critical minerals independence.
