General Motors has officially entered the grid storage market with a strategic investment in Peak Energy to manufacture next-generation sodium-ion batteries. With electricity demand rising and data centers consuming a growing share of US power, the battery conversation is shifting from familiar EV metrics to long-term grid reliability and affordability.

In this episode, we break down why GM's VP of Battery & Sustainability, Kurt Kelty, believes sodium-ion will be a "defining chemistry" for the future. We explore the massive advantages of sodium-ion technology, including its lower cost, stability over broad temperature ranges, and an incredible estimated 20,000-cycle lifespan, meaning they could last a half-century before needing replacement. Plus, because they have the potential to operate without active cooling, these systems require far less hardware, maintenance, and parasitic energy losses.

We also look at the booming US battery energy storage market, which hit a record 9.7 GWh in Q1 2026, and discuss the newly launched American Battery Leadership Coalition, an industry group pushing for US-made sodium-ion technology to reduce reliance on the Chinese supply chain. GM plans to prototype these stationary storage cells by late 2026, aiming for commercialization by 2028.
