Energy Storage in Compressed Air to Feed the Grid

A lot of hot air? Why energy storage matters

CNBC, January 12, 2015

People around the world are turning to renewable sources of energy such as the wind and sun, which offer a sustainable and abundant source of power for our homes, cities and offices. But what do you do when the sun isn’t shining or the winds aren’t fair?

However, compression produces a large amount of heat energy that is currently not used in the process. According to the Berkeley, California-based LightSail Energy, “Until now, this was wasted, drastically reducing efficiency.”
