In a sandy field on the edge of the Mojave Desert in Lancaster, California, an array of solar panels sit next to dozens of long white boxes that are filled with used batteries from electric cars. At the site, more than 1,000 old batteries from Nissan and Honda EVs now have a second life: During the day, they store electricity from the solar panels and excess energy from the electric grid. At night, when California homes need more power and the supply of solar drops, the startup that runs the system, B2U Storage Solutions, sends electricity back into the grid.
