Google Invests $425M in Redwood Amid Surging AI Power Demand
▼ Summary
– Google has joined Nvidia and other investors in a recent $425 million funding round for battery startup Redwood Materials, pushing its total capital raised to $4.9 billion.
– Redwood Materials, founded by ex-Tesla CTO JB Straubel, was originally created to build a circular battery supply chain by recycling scrap to recover materials like nickel and lithium.
– The company has expanded into a new energy storage business, repurposing used EV batteries to create micro-grids that can power AI data centers and industrial sites.
– This new venture, Redwood Energy, is a key attraction for investors due to the surging electricity demand from AI and data centers, which makes energy storage essential.
– Redwood claims to recover over 70% of used battery packs in North America and aims to deploy 20 gigawatt-hours of grid-scale storage by 2028.
Google has invested $425 million in Redwood Materials, a significant move that underscores the tech giant’s strategic focus on securing reliable energy solutions for its power-hungry artificial intelligence operations. This funding injection is part of a larger $425 million Series E round, which also saw continued participation from existing investors and a notable earlier investment from Nvidia’s venture arm. The capital will fuel Redwood’s expansion into a critical new area: building energy storage systems designed specifically to power AI data centers and large industrial facilities.
Founded by former Tesla executive JB Straubel, Redwood Materials began with a mission to establish a circular economy for batteries. The company initially processed manufacturing scrap and end-of-life consumer electronics, extracting valuable materials like lithium and nickel for resale to battery manufacturers. Over time, its business model has evolved dramatically. Beyond recycling, Redwood now produces battery cathodes and, most recently, launched an energy storage division named Redwood Energy.
This new venture addresses a pressing market need. The explosive growth of AI computing requires immense and constant electricity, placing unprecedented strain on power grids. Redwood Energy’s approach is to create micro-grids by repurposing electric vehicle batteries that are no longer suitable for transportation but still hold significant capacity for stationary storage. This gives these batteries a valuable second life before they are ultimately recycled.
The company’s capability in this arena is substantial. Redwood reports that it currently recovers over 70% of all used or discarded battery packs in North America. Last year, the company held an inventory exceeding 1 gigawatt-hour of storage capacity, with expectations to add another 4 gigawatt-hours shortly. Its ambitious roadmap aims for the deployment of 20 gigawatt-hours of grid-scale storage by 2028, positioning it as a major player in the infrastructure supporting the digital economy.
While the exact valuation from this latest funding was not officially released, sources indicate Redwood’s post-money valuation now exceeds $6 billion, a notable increase from previous rounds. This latest investment brings the company’s total capital raised to nearly $4.9 billion, reflecting strong investor confidence in its dual role as both a sustainability leader and a provider of essential energy infrastructure for the AI era.
