A GM energy display is seen at the New York International Auto Show on April 16, 2025.Danielle DeVries | CNBCGeneral Motors is expanding efforts to capitalize on the expected growth of energy storage and data centers by promoting different battery cell chemistries, while also offering more support for its electric vehicle owners to combat higher energy costs.The Detroit automaker detailed plans Tuesday to increase its vehicle-to-grid capabilities — in which a vehicle can provide energy to the electric grid — for its EV customers and develop next-generation sodium-ion batteries that GM's battery leader said "will reshape grid-scale energy storage."Both moves are meant to address concerns about rising energy costs amid an artificial intelligence boom. The stock market has speculated that vast sums of money will be spent on infrastructure to support a big data center buildout."Sodium-ion-powered energy storage systems have the potential to operate without active cooling and with much less system complexity," Kurt Kelty, GM's vice president of battery and sustainability, said Tuesday in a blog post. "In large energy storage systems, that matters."Not having to cool the battery cells could lead to lower upfront costs as well as operating costs, the automaker said.At a foundational level, a sodium-ion battery works much like a lithium-ion battery, but GM says it has the potential to perform across a wider range of
