How used EV batteries could help fuel the AI boom

The AI industry's burgeoning power demands, projected to triple U.S. data center electricity consumption by 2028, are being addressed by innovative solutions like Crusoe's use of repurposed EV batteries from Redwood Materials. This approach, combining solar energy with highly functional second-life lithium-ion batteries, offers a scalable and renewable alternative to traditional power sources, including new gas-fired plants. General Motors' recent partnership to supply EV batteries to Redwood Materials further validates the growing industry trend towards leveraging circular economy principles to sustainably power the energy-intensive AI boom.

Analysis

The accelerating power demands of the artificial intelligence sector, projected by a 2024 Department of Energy study to account for 12% of U.S. electricity consumption by 2028, are creating a significant bottleneck for growth. The article highlights an emerging, scalable solution that leverages the circular economy: repurposing used electric vehicle (EV) batteries for stationary energy storage to power data centers. AI cloud platform Crusoe is currently operationalizing this model in Nevada, using second-life batteries from Redwood Materials, which recovered over 20 gigawatt-hours of lithium-ion batteries in 2024. These batteries, while potentially losing up to 20% of their capacity for automotive use, remain highly effective for grid storage. The model's commercial viability and strategic importance are underscored by General Motors' new partnership to supply used EV batteries to Redwood Materials. This collaboration validates the second-life battery market as a practical alternative to building new fossil fuel infrastructure, such as gas-fired plants, to meet the AI industry's immediate power needs.

Key Decisions for Investors

• Investors should monitor the emerging sub-sector at the intersection of AI infrastructure, energy storage, and automotive supply chains, as solving the AI power bottleneck represents a primary growth catalyst.
• For General Motors (GM), this partnership with Redwood Materials is a positive strategic development that addresses EV battery lifecycle concerns and creates a potential new revenue stream by servicing the high-growth AI industry, enhancing its long-term ESG profile.
• The scalability of this second-life battery model is a key variable; investors should track further partnership announcements between automakers and energy storage firms, as these will be leading indicators of the market's maturation and a signal of which companies are effectively capitalizing on this trend.
• While Redwood Materials is private, its success highlights potential opportunities in publicly-traded companies specializing in battery recycling, materials recovery, and modular energy storage solutions positioned to serve the data center market.
