Read an interesting piece the other day about using liquid air to store surplus power from wind turbines. It used the surplus power to freeze air to minus 169C at which point it became liquid, It can then be stored in super insulated tanks at no pressure, much like liquid natural gas. When required it is rewarmed and becomes a much larger volume of air again and is used to drive turbines to generate power. There is pilot plant running apparently.
