Energy storage is one of the biggest challenges of our transition to a net zero electricity grid. These days, there are plenty of options to generate electricity - solar, wind, hydro - but far fewer options to store electricity.  

Storage is important because it can change renewable energy from volatile (generate a lot of electricity, cheaply when the sun is shining and the wind is blowing and then nothing at other times) to reliable. Right now, the world can’t move away from coal or gas as providers of baseload power - the always on, always reliable power source - because of the volatility of renewables.
