This Southern California solar farm is using retired EV batteries for storing the power and then send to the grid when needed. This way the retired batteries can extend their usefulness for several…::A Southern California company is showing how repurposing EV batteries for stationary storage can extend their usefulness for several years.
This is a way to get off gas as it’s used for reliability and voltage regulation. There’s a few locations running pilots with different energy storage techs like this. One of the main problems with integrating renewables is they aren’t dispatchable generation so you’re basically throwing unknowns in to the system. This is mediated through programs like demand response and load following with gas, but the goal of decommissioning gas and fossils entirely while still providing reliability is hampered because of this gap in capability. Renewables paired with storage would accommodate more less flexible renewables and SMRs, and allow for more electrification of the economy with less climate impact. More electric arc furnaces!
