Redwood Accelerates Energy Storage, Announces $350 Million Series E Funding

Redwood has closed a $350 million Series E funding round, led by Eclipse with participation from new strategic investors including NVentures (NVIDIA’s venture capital arm).

This oversubscribed round reflects the excitement and rapid growth across Redwood’s two core, integrated business lines:

Critical Materials: Cobalt, Nickel, Copper, Lithium and Cathode Active Material


Grid Energy Storage: very large scale, lowest cost, best integration

This is a pivotal time for both Redwood and the United States, as curtailment in international supplies overlaps with intense domestic demand growth for these same materials and energy products.

Electric energy availability has become a key strategic issue for AI infrastructure growth. Low-cost, large-scale battery energy storage has emerged as the most immediate and scalable solution to enable AI factory deployment and unlock stranded grid and generation capacity. Beyond powering data centers, this storage capacity will benefit industrial electrification and help address the intermittency of domestic renewable generation. Coupled with natural gas turbines and future nuclear generation, large scale energy storage can dramatically improve efficiency, utilization, and the reliability of those baseload assets.

By combining deep materials and manufacturing expertise with advanced power electronics and software, Redwood is creating a new generation of U.S.-made energy storage systems—scalable, low-cost, and designed to power data centers, industry, and the grid—reducing reliance on imported LFP batteries.

With this new capital, Redwood will accelerate the expansion of our energy storage deployments, refining and materials production capacity, and our world-class engineering and operations teams. We’re actively recruiting those who want to shape the next era of American energy leadership and critical-minerals independence. Join us!

We’re grateful to our many existing partners participating in this investment and excited to welcome new investors as we take the next steps toward building a resilient, dominant U.S. energy future.
