GM’s Bold Energy Initiative: Sodium Batteries and EVs That Power the Grid

Key Takeaways

General Motors is diversifying into energy, developing sodium-ion batteries and integrating EVs into the energy grid.
GM aims to connect 52,000 EVs to the grid and simplify charging with its new Energy Pass tool.
The automaker is investing $900 million in battery research to reduce reliance on Chinese supply chains.

GM’s Transition into Energy Sector

General Motors (GM), America’s largest automaker by sales, is evolving into a significant player in the energy sector. At a recent event in San Francisco, GM announced plans to develop sodium-ion batteries for energy storage systems (ESS). This initiative will complement its goal of connecting 52,000 electric vehicles (EVs) to the grid by the decade’s end, while also introducing a new app called Energy Pass aimed at simplifying charging across various networks.

Sodium-Ion Battery Development

Under the leadership of Kurt Kelty, vice president of battery and sustainability, GM’s battery strategy has expanded to include several types, including lithium iron phosphate (LFP) for affordable models like the Chevy Bolt and high-nickel cells for current vehicles. Sodium-ion is the latest addition, promising significant benefits. According to Kelty, “We believe that you have to have the right battery for the right application.”

With U.S. EV sales currently cooling post-expiration of federal tax credits, GM is shifting focus to grid-scale energy storage to utilize its battery production capacity effectively. The demand for ESS is growing, spurred by the needs of power-hungry AI data centers. Sodium-ion batteries, which GM is co-developing with startup Peak Energy, will be lower-cost, more efficient, and less complex compared to traditional batteries, requiring no active cooling and maintaining performance in extreme temperatures.

An essential goal for GM is to reduce North America’s dependency on Chinese battery supply chains. The raw materials required for sodium-ion batteries have abundant local reserves, meaning this could translate into a North American battery industry. Kelty noted, “Ultimately, this should be a North American battery,” given that sodium is significantly more abundant than lithium and has a smaller environmental impact. The automaker’s investment of $900 million into battery research underlines this commitment as a strategic move against potential geopolitical disruptions.

EVs as Power Banks and Improved Charging Solutions

Beyond battery development, GM is also focusing on making its EVs more integrated into energy solutions. Currently, there are approximately 250,000 GM EVs on U.S. roads, and if all were connected to the grid, they could potentially power 120,000 homes for up to one week. GM is introducing vehicle-to-home bidirectional charging options and plans to release a firmware update enabling these vehicles to send energy back to the grid.

Collaborating with Pacific Gas & Electric, GM aims to connect 52,000 EVs to enhance grid reliability. By utilizing the idle energy in parked EVs, homeowners can lower energy costs while assisting utilities in managing power demands from other sectors, such as data centers.

Additionally, GM introduced the Energy Pass app, designed to streamline the charging process for EV owners across multiple networks, including Electrify America and Tesla Supercharging. All 2027 model year GM EVs will feature a native charging port, further simplifying the user experience.

While Tesla has established itself in this space with products like the Powerwall and Megapack, GM faces competition as it aims to pivot successfully into energy solutions. Last year, GM reported $7.1 billion in losses associated with its slowing EV ambitions. As the market shifts, the extent of GM’s success in this energy venture will be determined over time, but it positions itself strategically amidst changing sales dynamics.
