Why everyone’s an energy company now

In a rapidly evolving landscape, major automakers like Tesla, Ford, and General Motors (GM) are increasingly venturing into the energy storage sector. With electric vehicle (EV) sales plateauing in the U.S., the market for large stationary batteries has experienced a remarkable doubling over the past two years, showing no signs of slowing down. Despite significant cuts to incentives in recent legislation, the Solar Energy Industries Association anticipates that annual installations will surpass 110 GWh by 2030, almost doubling current figures. Kurt Kelty, GM's vice president of battery and sustainability, emphasized the market's vast potential. GM is taking a bold step forward by introducing a new sodium-ion battery technology aimed at capturing market share. The surge in energy storage demand is fueled by the growth of data centers, particularly those supporting artificial intelligence, with energy needs projected to nearly triple by the decade's end. Additionally, sectors such as transportation, manufacturing, and HVAC are increasingly becoming electrified, creating further opportunities for growth. Beyond traditional automakers, startups are also seizing this opportunity. Base Power recently secured a $1 billion Series C funding round, while Lunar Energy has raised $232 million to offer batteries directly to homeowners. Others, like Lightship, are innovating by providing mobile battery solutions for various job sites. Currently, Tesla dominates the energy storage market, accounting for 82% of the 57 gigawatt-hours installed last year. The company's revenue from energy generation and storage has doubled since 2023, buoyed by its Megapack and Powerwall products, with profits in this segment significantly outpacing traditional vehicle sales. However, GM is approaching this market with caution. Its sodium-ion cells are not expected to be ready until later this decade, as the company focuses on developing a product that meets market needs. Kelty highlights the advantages of sodium-ion technology, noting its affordability, durability, and the absence of a need for active cooling systems. While GM could have opted for a more straightforward approach by enhancing its existing lithium-ion battery production, it remains optimistic about the long-term prospects of EVs. The automaker is also working on a new lithium-manganese-rich (LMR) battery chemistry set to launch in 2028, aiming to reduce EV costs by approximately 10%. Sodium-ion technology, although currently heavier and with less range compared to lithium-ion, presents a compelling option for cost-effective EVs. It offers rapid charging capabilities and a lower risk of fires, making it an attractive alternative. Kelty acknowledges the uncertainty surrounding the long-term viability of sodium-ion batteries but remains committed to exploring all avenues to expedite entry into the market. GM's strategic approach aims to ensure it remains competitive, even amidst potential market fluctuations.
