Redwood Materials Announces Final Close of $425 Million Series E to Scale Energy Storage

Redwood Materials, securing U.S. critical materials, powering America’s energy future, led by JB Straubel, Chris Lister, Colin Campbell, and others, has announced Series E financing, bringing the total raise to $425 million, with continued participation from existing investors, Capricorn and Goldman Sachs Alternatives, and welcomes Google as a new investor.  

Driven by strong demand, the increase from the previously announced $350 million underscores confidence in the long-term strategy and execution. The capital will accelerate the energy storage platform and further strengthen the integrated recycling and critical minerals business.

As electricity demand surges from AI, data centers, manufacturing, and electrification, energy storage is becoming essential infrastructure, not optional.

These investments position Redwood to lead grid reliability, energy security, and the next phase of modern power infrastructure, with disciplined capital deployment and a relentless focus on scaling a domestic battery ecosystem.
