2nd-Light promotes circular economy for Lithium-ion batteries, a type of waste that poses a severe environmental and safety hazard. By repurposing these end-of-life batteries, less new batteries are manufactured as well as end up in land-fills, or recycled in an energy intensive process. Each commercial second-life storage system reduces as much as 16.7 tons of CO2 compared to new storage systems. In general, storage systems introduced to the electricity grid enable for more renewable energy to be integrated and by that reduce CO2
