Redwood Materials has secured $350 million in a Series E funding round led by Eclipse, with additional participation from NVIDIA’s venture capital arm, NVentures. The oversubscribed financing highlights strong investor confidence in the company’s two integrated business segments: critical materials production and grid-scale energy storage.
In its critical materials division, Redwood focuses on sourcing and refining cobalt, nickel, copper, lithium and cathode active materials. Its grid energy storage arm develops large-scale battery systems designed to deliver low-cost, highly integrated solutions for utilities, industrial users and data centers.
The funding comes at a critical moment for the United States, as global supply chain constraints coincide with rapid domestic growth in demand for both battery materials and energy storage capacity. Affordable, large-scale energy storage is increasingly viewed as the most scalable approach to support expanding artificial intelligence infrastructure, unlock underutilized grid capacity and stabilize intermittent renewable generation.
By integrating its materials expertise with advanced power electronics and software controls, Redwood is building the next generation of U.S.-manufactured energy storage systems. These systems are engineered to support data centers and industrial facilities, while also bolstering grid reliability when paired with natural gas turbines and anticipated nuclear capacity. The company aims to reduce reliance on imported lithium-iron-phosphate batteries by delivering home-grown solutions that meet stringent performance and cost requirements.
The newly raised capital will accelerate expansion across all areas of the business, including additional energy storage deployments, increased refining and materials production capacity, and growth of its engineering and operations teams. Redwood has signaled an active recruitment effort to attract professionals eager to advance American energy leadership and strengthen critical-minerals independence.
Redwood Materials expressed gratitude to its existing investor base and extended a welcome to new backers as it moves forward with its mission to build a resilient, U.S.-centric energy infrastructure.
