On April 20, 2026, electric vehicle (EV) manufacturer Rivian Automotive Inc. (RIVN) announced a strategic partnership with battery circular economy firm Redwood Materials to deploy second-life EV battery packs into a stationary energy storage system for its Illinois assembly plant. The collaboration
Key Developments
Redwood Materials first launched its dedicated Redwood Energy business unit in June 2025, focused on manufacturing low-cost stationary energy storage systems for AI data centers and commercial end users facing rising grid constraints. Per company statements, the Redwood Energy system deployed at Rivian’s facility uses proven, safe second-life EV batteries, offering significant cost savings and flexible, rapid deployment at high-demand sites. Rivian noted the system will allow it to draw on store
Market Impact
The partnership marks Rivian’s entry into the fast-growing stationary energy storage market, joining peer automakers that are diversifying revenue streams amid softer-than-anticipated consumer EV demand following billions in sector capital expenditures. General Motors signed a non-binding memorandum of understanding with Redwood Materials in July 2025 to deploy stationary storage systems using new and second-life GM EV batteries, while Ford repurposed its Kentucky BlueOval SK battery plant in De
In-Depth Analysis
This collaboration addresses two overlapping structural shifts in the U.S. energy and mobility markets: first, the growing mismatch between exponential electricity demand from AI data center expansion and lagging grid capacity additions, and second, the growing supply of end-of-life EV batteries as early EV cohorts reach retirement age. For Rivian, monetizing second-life battery residual value improves full-cycle battery unit economics, supporting long-term total cost of ownership competitiveness for its passenger and commercial EV lines. Redwood Materials’ competitive moat, anchored by founder JB Straubel’s background as Tesla co-founder and former CTO, gives it unique expertise in validating second-life battery performance and safety for stationary use cases. The 600 GWh 2030 U.S. storage demand estimate cited by Rivian implies a 31% compound annual growth rate for the domestic stationary storage market over the 2026-2030 period, far outpacing the 6% CAGR projected for U.S. grid generation capacity expansion over the same window. While the initial deployment is limited to Rivian’s internal facility, successful pilot performance could position the company to launch commercial storage solutions for data center and industrial clients as early as 2027. We retain our neutral rating on RIVN shares, as the partnership is expected to contribute less than 2% of projected 2027 revenue, with upside tied to successful commercial scaling of the storage segment.
