China again dominated global battery storage deployments in August, accounting for two-thirds of what came online, but Europe, North America and Australia had good months too.
Energy storage
Grid-scale storage refers to technologies connected to the power grid that can store energy and then supply it back to the grid at a more advantageous time – for example, at night, when no solar power
