In a world that increasingly depends on data flows for its functioning, the storage of energy and its controlled release are key technologies that through smartphones and laptops underpin much of daily life at work and at home.
The battery technologies that power the supercomputers in our pockets are, when scaled up and linked together to form battery energy storage systems, also helping to change the shape of the energy industry. Storage system benefits include freeing renewable energy production from the vagaries of the weather by allowing power to be stockpiled when the weather permits – when the sun is up, or the wind is blowing – for use when it is required.
Batteries can also be recharged from the grid when demand is low and electricity is cheap, for example overnight. This all adds up to increased penetration of renewables, to everyone’s benefit – in homes, cities and businesses.
