General Motors (GM) is making waves in the tech world by dipping its toes into the emerging energy storage sector. In an interview with TechCrunch, GM unveiled two key phases of their strategic push into this space: a collaboration with energy-storage startup Peak Energy and an investment in sodium-ion battery technology. This move could potentially revolutionize how we store power for both data centers and grid-scale deployments.
Kurt Kelty, vice president of battery and sustainability at GM, explained that the primary motivation behind these initiatives is to secure a competitive edge through energy storage rather than directly competing with traditional automotive business lines. Sodium-ion batteries are a compelling choice due to their cost-effectiveness, longevity, and reduced risk of overheating compared to lithium-ion alternatives. However, they require more bulk for similar energy storage capacities.
The collaboration with Peak Energy is particularly noteworthy as it involves developing an entirely new sodium-ion chemistry specifically tailored for grid-scale deployments. This marks the first such move by any automaker outside of China. GM’s investment includes a dedicated battery-development center and a $900 million commitment to commercialize these new technologies.
While the sodium-ion cells are still years away from commercial production, GM plans to sell lithium iron phosphate (LFP) cells to LG Energy Solution for use in their energy-storage systems. This partnership leverages GM’s existing work through its Ultium joint venture, which supplies batteries for EVs.
In addition to these battery-focused strategies, GM is also expanding its collaboration with Redwood Materials, a battery-recycling and energy-storage startup co-founded by former Tesla executive J.B. Straubel. This partnership includes the purchase of Redwood systems for use in one of GM’s Michigan plants, expected to save approximately $3 million over its lifetime.
The move towards energy storage is not just about immediate cost savings or technological innovation; it's also about aligning with broader sustainability goals and securing a future where both automotive and industrial sectors can benefit from advanced battery technologies. As GM continues to expand its footprint in this space, the potential impact on the industry and beyond could be significant.
