A Sodium-Aluminum Battery Aims to Integrate Renewables for Grid Resiliency

A new battery design could help ease integration of renewable energy into the nation’s electrical grid at lower cost, using Earth-abundant metals, according to a study just published in Energy Storage Materials. A research team, led by the Department of Energy’s Pacific Northwest National Laboratory, demonstrated that the new design for a grid energy storage battery built with the low-cost metals sodium and aluminum provides a pathway toward a safer and more scalable stationary energy storage system.
